The acceleration due to gravity on the surface of the Earth is:

Explain an activity to show that,during a free fall,heavier and lighter objects accelerate at the same rate.

$A$ body weighs $63 \, N$ on the surface of the earth. What is the gravitational force on it due to the earth at a height equal to half the radius of the earth (in $, N$)? (Given: Mass of the earth $= 6 \times 10^{24} \, kg$ and radius of the earth $= 6.4 \times 10^{6} \, m$)

$A$ ball is thrown vertically upward,acceleration due to gravity is:

An iron sphere of mass $30 \, kg$ has the same diameter as an aluminium sphere whose mass is $10.5 \, kg$. The spheres are dropped simultaneously from a cliff. When they are $10 \, m$ from the ground,they have the same:

Give an example of the motion of an object under the influence of gravitational force on Earth.
