Question

when a body falls freely under gravity then it moves with a constant​

Answer 1

Explanation:

body falls with acceleration 'g' due to gravity under the influence of gravitational force until the buoyancy force balances it. When the resultant force acting on the object becomes zero, it attains a velocity called terminal velocity. Mass is constant. And the gravity which is also constant...

Answer 2

When a body falls freely under gravity, then it moves with a constant acceleration.

• When a body falls freely it is a motion phenomenon where a continuous acceleration can take place. Typically acceleration is constant and down due to gravity. It's so even if it throws up an object, or has zero velocity.
• If a force that is acting on a body consist of a component in the displacement direction, then the work performed by force is positive.
• Therefore the work done by gravity is also positive when a body falls freely under the influence of gravity.
