Answer 2

when a body is dropped from a tower , then there is an increase in its ..

1. mass
2. velocity
3. acceleration
4. potential energy

answer : option (2) velocity

explanation : mass of a body always remains constant during its motion.

     as body is falling downward, a constant force ( gravitational force acting on this body) so the acceleration of the body also remains same.

      potential energy depends on the height of a body from the ground. if a body is dropped from a tower, height of body from the ground will decrease so the potential energy of the body will decrease.

      but velocity of the body changes because a constant acceleration (acceleration due to gravity) is acting on this body.

∵ v = u + at , here, u = 0 , a = g ⇒ v = gt , this equation shows that velocity varies with time. it means velocity increases with time.

therefore when a body is dropped from a tower , there is an increase in its velocity.
