Question

1. Define 1 joule of work?

2.Write an expression for the kinetic energy of an object.​

Answer 1

✨✨Answer:-✨✨

1)

1 Joule is the energy used to accelerate a body with a mass of one kilogram using one newton of force over a distance of one meter.

The SI unit of energy is joule (J).

2)

If a body mass m is moving with a velocity v, then its kinetic energy

is given by the expression:

K.E. = 1/2mv2

Where, m = Mass of the object

v = velocity of object

Its SI unit is Joule (J).

Hope it helps you..

Answer 2

1..

It is denoted by J

2..

mass m is moving with a velocity v, then its kinetic energy

K.E. = 1/2 mv2
