Explanation:

Kinetic energy is the energy of motion. There are two types - linear (related to its velocity) and rotational (related to its angular velocity). Linear kinetic energy is given by:

K, start subscript, l, i, n, end subscript, equals, one half, m, v, squared.

where m, left bracket, k, g, right bracket,m(kg) is its mass, and v, left bracket, m, comma, s, to the power minus 1 , right bracket,v(m,s

) is its speed. Kinetic energy is a scalar quantity (it has no direction). Numerically, the kinetic energy is equal to the steady resultant force needed to stop the object in a distance of 1, m,1m. This is different to the momentum which is a vector quantity and is numerically equal to the force needed to stop the object in 1, s,1s.

Rotational kinetic energy is given by:

K, start subscript, r, o, t, end subscript, equals, one half, I, omega, squared.

The SI units of kinetic energy are joules, J,J.
