Linear motion is motion along a straight line, and can therefore be described mathematically using only one spatial dimension. It can be uniform, that is, with constant velocity (zero acceleration), or nonuniform, that is, with a variable velocity (nonzero acceleration). The motion of a particle (a pointlike object) along the line can be described by its position x, which varies with t (time). Linear motion is sometimes called rectilinear motion.
An example of linear motion is that of a ball thrown straight up and falling back straight down.
The average velocity v during a finite time span of a particle undergoing linear motion is equal to
 v = \frac {\Delta d}{\Delta t}.
The instantaneous velocity of a particle in linear motion may be found by differentiating the position x with respect to the time variable t. The acceleration may be found by differentiating the velocity. By the fundamental theorem of calculus the converse is also true: to find the velocity when given the acceleration, simply integrate the acceleration with respect to time; to find displacement, simply integrate the velocity with respect to time.
This can be demonstrated graphically. The gradient of a line on the displacement time graph represents the velocity. The gradient of the velocity time graph gives the acceleration while the area under the velocity time graph gives the displacement. The area under an acceleration time graph gives the velocity.
Linear motion is the most basic of all motions. According to Newton's first law of motion, objects not subjected to forces will continue to move uniformly in a straight line indefinitely. Under everyday circumstances, external forces such as gravity and friction will cause objects to deviate from linear motion and can cause them to come to a rest.
For linear motion embedded in a higherdimensional space, the velocity and acceleration should be described as vectors, made up of two parts: magnitude and direction. The direction part of these vectors is the same and is constant for linear motion, and only for linear 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. solution : 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).
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.
Answers:You are correct. Inertia is the tendency of an object to resist changes in its current state of motion or rest.
