Examples of Inertia in Motion
Inertia is the natural tendency of an object to resist any change in its motion, which means that it tends to stay at rest or in constant motion along a straight line.
Inertia is a quality of mass and in turn the mass of an object is actually a measurement of its inertia.
Bodies will have different inertia due to their difference of mass. An object with little mass with little inertia will have greater acceleration than an object with larger mass and larger amount of inertia and this will be in response to same net force acting on both.
As objects have inertia, they resist changing their motion and this leads to applying more forces to things going and change the velocity and ultimately change in acceleration.
The inertia of an object at rest is called static inertia and the one in motion is called dynamic inertia.
Since the inertia of motion is the inability of the body to change its state of motion by itself the examples would also show the same trend.
Some examples of inertia of motion are as follows:
(a) A person trying to get down from a running bus falls forward.
Explanation: when the person gets down from a running bus the upper part of his body is still in motion and due to this inertia of motion the body topples forward even though he has set his foot on the ground.
(b) Passengers travelling by train fall forward when the train applies sudden brake
Explanation: due to inertia of motion the motion of all passengers is equal to the motion of the train and as soon as the brake is applied the passengers feet being in contact with the train floor stops while the upper part falls forward due to inertia of motion.
(c) Ripe fruits fall from the trees in the direction of wind.
Explanation: the tree sways along with the wind and the inertia of motion makes these fruits sway along with the tree branches. The fruits fall off due to the inertia of motion along the direction of wind.
(d) The swirling of milk in a glass continues even after the stirring is stopped.
Explanation: a person stirring a spoonful of sugar into a glass of milk finds the milk continuing the swirling movement even after the stirring is stopped and this happens due to the inertia of motion of the milk inside the glass.
(e) A toy thrown up by a boy inside a moving train moves along with the train
Explanation: the toy also attains the same velocity as the train inside the train and thus would move along with the train when thrown up. This will apply only when the train is moving with a constant speed or it might fall forward or backward if the speed is altered.

Question:examples of 3 laws of motion
Answers:Newton first law of motion:every body continues to remain in its state of rest or uniform motion along a straight line unless it is compelled by external force to change that state.
First law of newton is also called the law of inertia.
ex : A person sitting in a vehicle at rest has his whole body at rest.when the vehicle suddenly starts moving forward,the lower part of in contact with the vehicle moves forward.But the upper part of the body continues too remain at rest due to inertia.As a result,the person has a tendency to fall back.
Newton second law of motion:The acceleration given to a body is directly proportional to the force and inversely proportional to the mass and it takes place in the direction of force.
ex : A force of 0.12N acts for 3 seconds on a body of mass 0.4 kg at rest.Find the velocity gained by the body.
F=0.12 N, m =0.4 kg and t = 3 s.
using the equation F = ma,
0.12 = 0.41 therefore a = 0.12/0.4 = 0.3 meter per second square
Initial velocity of the body U = 0
so final velocity of the body is given by
v = u + at
0 + 0.3 * 3 = 0.9 meter per second square
Third law of newton states that to every action there is any equal and opposite reaction.
ex:When a body reaming at rest on a table.The body exerts a downward force on the table equal to its weight (action).The table in turn,exerts on the body an equal force in the opposite direction (reaction).
Question:I am looking for somewhat like an example where this law of motion is applied.. thanx.. 10 poitns here!!!!!!!!!!!!!!!!
Answers:Basketball is a great example for the law of motion.
The law of inertia can be seen when you are doing a lay-up. As you are running up to the basket, your body is going a certain speed in motion. Once you jump for the lay-up your body (and the ball) want to continue in the direction you were running and at the speed you were running. That is why sometimes people go under/behind the board.
Acceleration can be seen in the same example; as you move toward the basket, you steadily increase. Once you throw the ball, it will accelerate and decelerate according to how gravity, air resistance, and all other forces (like the net or backboard) act upon it.
Question:I am doing a science project . Is a girl riding a surf board considered to be Newtons first law of motion ? I have a science Project and isnt a girl riding a surfboard considered to be Newtons first law? & Newtons First law, isnt it An object will stay at rest unless another object will act upon it???
Answers:Theoretically, this is a scenario where the three Laws Of Newton can be applicable.
Anyway, Newton's 1st Law is also known as the Law of Inertia and fora science project, I would suggest a very simple demonstration like so.
Place a block (or any object) on a smooth table. Note that this block is not moving initially. If you apply an external force on it (in other words, push or pull it), the block will obviously move consistent with the direction of the applied force.
If the external force is taken off (i.e., you stop pushing or pulling), the block will simply stop. Another way the block will stop is when something stops it from moving. It could be an impediment or simply anything that will prevent the block from moving.
Hope this helps.
Inertia :Check us out at www.tutorvista.com Inertia is the resistance of any physical object to a change in its state of motion. It is represented numerically by an object's mass. The principle of inertia is one of the fundamental principles of classical physics which are used to describe the motion of matter and how it is affected by applied forces. Inertia comes from the Latin word, "iners", meaning idle, or lazy. In common usage, however, people may also use the term "inertia" to refer to an object's "amount of resistance to change in velocity" (which is quantified by its mass), or sometimes to its momentum, depending on the context (eg "this object has a lot of inertia"). The term "inertia" is more properly understood as shorthand for "the principle of inertia" as described by Newton in his First Law of Motion. This law, expressed simply, says that an object that is not subject to any net external force moves at a constant velocity. In even simpler terms, inertia means that an object will always continue moving at its current speed and in its current direction until some force causes its speed or direction to change. This would include an object that is not in motion (velocity = zero), which will remain at rest until some force causes it to move. On the surface of the Earth the nature of inertia is often masked by the effects of friction, which generally tends to decrease the speed of moving objects (often even to the point of rest), and by the acceleration due to gravity.

Newton's Laws Of Motion (1) : The Law Of Inertia :ESA Science - Newton In Space (Part 1): Newton's First Law of Motion - The Law of Inertia Newton's laws of motion are three physical laws that form the basis for classical mechanics. They have been expressed in several different ways over nearly three centuries. --- Please subscribe to Science & Reason: www.youtube.com www.youtube.com www.youtube.com --- The laws describe the relationship between the forces acting on a body and the motion of that body. They were first compiled by Sir Isaac Newton in his work "Philosophi Naturalis Principia Mathematica", first published on July 5, 1687. Newton used them to explain and investigate the motion of many physical objects and systems. For example, in the third volume of the text, Newton showed that these laws of motion, combined with his law of universal gravitation, explained Kepler's laws of planetary motion. --- Newton's First Law of Motion An object in motion will stay in motion, unless an outside force acts upon it. There exists a set of inertial reference frames relative to which all particles with no net force acting on them will move without change in their velocity. Newton's first law is often referred to as the law of inertia. en.wikipedia.org .
