A ball is thrown vertically upwards. After some time, it returns to the earth. Draw a speed-time graph for the ball (neglect air resistance).
Important Questions on Motion
When acceleration is constant, can the direction of velocity of a body change? If yes, how?
State if the following situation is possible and give an example for it.
A body with acceleration but with zero velocity.
State if the following situation is possible and give an example for it.
A body moving horizontally but having acceleration in the vertical direction.
State if the following situation is possible and give an example for it.
A body moving with a constant velocity in an accelerated motion.
What do you understand by the term acceleration? When is acceleration positive and when is it negative? State the units of acceleration in SI system.
Derive the three equations of motion graphically considering uniform acceleration.
A body projected vertically upwards returns to the point of projection after a few seconds. Draw a displacement-time graph for the motion of the body. The displacement is measured from the point of projection.
