Question

what is kinetic energy ?Write its expressions​

Answer 1

Answer:

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

Answer 2

Explanation:

kinetic energy is directly proportional to mass of the object and the square of its velocity k. E=1/2mv2
