Question

What do you mean by kinetic energy and fin it expression?

Answer 1

ANS: PARTICLES OF THE MATTER ARE  CONTINUOUSLY MOVING, THAT IS, THEY POSSESS WHAT WE CALL THE KINETIC ENERGY.

EXAMPLE: AS THE TEMPERATURE RISES, PARTICLES MOVE FASTER. SO, WE CAN SAY THAT WITH THE INCREASE IN TEMPERATURE THE KINETIC ENERGY OF THE PARTICLES ALSO INCREASES.

THANK U..

MAY THIS IS HELP FULL TO U ..

Answer 2

Answer:

Explanation:

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.
