An object that has kinetic energy must have
a) acceleration.
b) momentum.
c) a force applied to maintain it.
d) none of the above

B. Momentum

Explanation:

There is a correlation between Momentum and Kinetic Energy. Both are variables that depend to some extent on speed and mass. Therefore, if a body has a certain speed, it will have a momentum and a kinetic energy.

If you write down the formulas for kinetic energy

and momentum

You can write the energy in terms of momentum

Despite this, there is an important difference: the moment is a vector quantity: it has a direction in space, these moments have the same ability to 'add up' in direction and magnitude as the vectors of forces for example. On the other hand, kinetic energy is a scalar quantity, which implies that it has no direction in space.
