Question

When an object falls freely to the earth, the gravitational force acting on the body

• A. act opposite to the direction of motion
• B. acts along the direction of motion
• C. is a constant
• D. is equal to zero

Answer 1

Answer: (B)

The correct option is B

acts along the direction of motion

The direction of acceleration is same as the force acting on the body. As we know gravitational force is attracting always and direction of force is always towards the center of another body and g is acceleration due to gravitational force, so direction of force/acceleration will be towards the center of earth.

Also force depends on distance between the two bodies so it is not constant.

So option B is correct.
