Question:Our physics teacher drew a velocity-time graph showing a slanted ,straight line from the bottom left corner to the top right corner. This obviously means that it is uniform acceleration, and non-uniform motion , because in acceleration , the body is covering unequal distances in equal time intervals. But the teacher labeled it as a 'velocity-time for uniform motion when the object starts from rest' When i contradicted , he refused. Please help me.

Answers:uniform motion is not necisarily motion atthe same speed. uniform motion is where there is some regularity in the motion. an equal and exponential increase in velocity, is considered uniform motion.

Question:the concept is from physics, reveal the truth and misconception related to it

Answers:The movement may be sustaining a constant speed, but the body receives a constant acceleration: the centripetal force. If this force is of constant amplitude, it however changes constantly in direction!

Question:Q 1.a body moving with constant speed has uniform motion while a freely falling object has non uniform motion. why? Q 2.can a body have acceleration while at rest? give eg. Q 3. what type of motion is associated with a pendulum? Q 4. what does the rate of change of angular velocity refer to? Q 5. a boy after going around a circular track of radius 'r' comes back to the starting point. a)what is the displacement of the body? b)what is the total distance covered by him?

Answers:Q1. Uniform motion definition (my guess): Same distance covered every second, which also means a constant velocity. Free fall has an increasing velocity every second. Q2. Yes. You are accelerating right now while reading this. Gravity is causing you to ALWAYS accelerate while on earth. Q3. Simple harmonic motion Q4. Angular acceleration Q5. The displacement is 0 (starting position minus ending position).The distance covered is 2*pi*r (circumference)

Question:hi folks! need sample problems with sol'n about uniformly accelerated motion with 2 object as given. tnx

Answers:consult a physics book.. they have a lot of problems there. =D
