Gravitational force acts on all objects in proportion to their masses. Why then, a heavy object does not fall faster than a light object?
Fill in the following blank with suitable word :
The acceleration due to gravity on the moon is about ………………of that on the earth.
What do you mean by the term free fall ?
What do you understand by the term 'acceleration due to gravity of earth' ?
The values of g at six distances A, B, C, D, E and F from the surface of the earth are found to be 3.08 m/s2, 9.23 m/s2, 0.57 m/s2, 7.34 m/s2, 0.30 m/s2 and 1.49 m/s2, respectively.
(a) Arrange these values of g according to the increasing distances from the surface of the earth (keeping the value of g nearest to the surface of the earth first)
(b) If the value of distance F be 10000 km from the surface of the earth, state whether this distance is deep . inside the earth or high up in the sky. Give reason for your answer.
A force acts for 0.1 s on a body of mass 2.0 kg initially at rest. The force is then withdrawn and the body moves with a velocity of 2 m s-1. Find the magnitude of the force.
A body falls freely under gravity from rest and reaches the ground in time t. Write the expression for the height fallen by the body.
