The value of g does not depend on the:

1. Height of the body
2. Mass of the body
3. Shape of the body
4. All of these

Free fall of a body near earth's surface is an example of:

1. Uniform acceleration
2. Uniform velocity
3. Variable acceleration
4. None of these

A body when projected up with an initial velocity u goes to a maximum height h in time t and then comes back at the point of projection. The correct statement is —

1. The average velocity is 2h/t
2. The acceleration is zero
3. The final velocity on reaching the point of projection is 2u
4. The displacement is zero

Identify the correct statement from the following :

1. The average speed of a body can be zero even if it's average velocity is not zero.

2. Speed and velocity both are scalar quantities.

3. The magnitude of velocity of a body in motion is its speed.

4. Speed and velocity can be positive or negative depending upon the direction of motion.
