Front

Which of the following is an example of uniformly accelerated motion? A train traveling at a constant speed, A ball thrown out from a high window, Bicycles moving at the same speed in the street, A bullet traveling in a straight path at constant speed.

Back

A ball thrown out from a high window

Front

Which among the statements is true about uniform motion and uniformly accelerated motion? Options: In uniformly accelerated motion, positive constant acceleration will result in a constant velocity. The distance versus time graph of the object under uniform motion is a straight line, while uniformly accelerated motion has a parabolic curve. In uniform motion, it involves constant velocity with zero acceleration, while uniformly accelerated motion involves changing velocity with a constant acceleration. Uniform motion indicates a velocity that covers the same amount of distance at certain time intervals, while uniformly accelerated motion covers an increasing distance at a constant velocity.

How does a non-zero initial velocity projectile compare to one with zero initial velocity?

Back

The projectile will have a longer range along the horizontal than an object with zero initial velocity.
