Answer 2

Question : Define kinetic energy

Answer : In physics, the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

Question : write two examples of kinetic energy

Answer : 1. semi-truck travelling down the road has more kinetic energy than a car travelling at the same speed because the truck's mass is much more than the car's.

Answer : 1. semi-truck travelling down the road has more kinetic energy than a car travelling at the same speed because the truck's mass is much more than the car's.2. A river flowing at a certain speed comprises kinetic energy as water has certain velocity and mass.
