A stone is released from the top of a tower of height 19.6 m calculate it's final velocity just before touching the ground.

A ball is thrown vertically upwards with a velocity of 49 m/s Calculate. (i) The maximum height to which it rises. (ii) The total time it takes to return to the surface of the earth.

Gravitational force on the surface of the moon is only 1/6 as strong gravitational force on the earth. What is the weight in newtons of a 10 kg object on the moon and on the earth ?

Why will a sheet of paper fall slower than one that is crumpled into a ball ?

Amit buys few grams of gold at the poles as per the instruction of one of his friends. He hands over the same when he meets his friend at the equator will the friend agree with the weight of gold bought ? If not, why ? [Hint : The value of g is greater at the poles than at the equator]
