Area under velocity-time graph tells us the
Horizontal distance travelled by a ball if it's thrown with initial velocity of 20 m s -1 at an angle of 30° is
If we get a straight line with positive slope then its acceleration is
Acceleration of train when it is moving steadily from 4.0 m s -1 to 20 m s -1 in 100 s is
An object whose velocity is changing is said to be in a state of
