Question

Define energy?Give its SI unit?

Define kinetic energy?

Write an expression for kinetic energy of an object?

Answer 1

Answer:

1. In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. ... The SI unit of energy is the joule, which is the energy transferred to an object by the work of moving it a distance of 1 metre against a force of 1 newton
2. energy which a body possesses by virtue of being in motion.
3. 1/2MV^2. The kinetic energy of a body can be determined by calculating the amount of work required to set the body into motion with the velocity v from its state of rest.

Answer 2

$\bf \huge {\underline\purple{❥answer}}$

The International Standard Unit of Kinetic Energy is Joules(J). ( J = kg. MATHEMATICAL EXPRESSION FOR KINETIC ENEGRY. Kinetic Energy = 1/2 * m * where, m is the mass of the object and v is the velocity with which the object is moving.
