Question

An object is allowed to fall freely from a height of 10m.When it is 5 m above the ground,it will possess

• A. Half potential energy and half kinetic energy
• B. More potential energy than kinetic energy
• C. More kinetic energy than potential energy
• D. Only potential energy

Answer 1

The correct option is A Half potential energy and half kinetic energy

Since the ball is in free-fall, the only force acting on it is gravity.
Therefore, we can use the principle of conservation of mechanical energy - initially the ball has potential energy and no kinetic energy. When it is 5 m above the ground,it will possess half potential energy and half kinetic energy.
Hence, option A is correct.
