Question

.(i) What is Kinetic Energy ?
(ii) If a body of mass 5 kg is moving along a straight line with velocity 10 ms^ -1
and acceleration 20 ms^-1. Find its kinetic energy after 10 sec.
​

Answer 1

Answer:

1. Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.

Answer 2

Answer:

Kinetic energy is the energy which possess due to it's motion. Kinetic energy =250 joules
