Question

what is the definition of energy in scientific terms?
a force used on an object
the motion of an object
the ability to do work
a change in temperature

Explanation:

Energy is defined as the ability to do work. Work is done when a force causes an object to move. Force (a force used on an object) is \(F = ma\) (Newton's second law, \(m\) - mass, \(a\) - acceleration). The motion of an object relates to kinetic energy (\(KE=\frac{1}{2}mv^{2}\)), but energy is a broader concept. A change in temperature relates to thermal energy (e.g., \(Q = mc\Delta T\), \(Q\) - heat, \(m\) - mass, \(c\) - specific heat capacity, \(\Delta T\) - temperature change), but again, it's a subset. The most general scientific definition is the ability to do work.

Answer:

the ability to do work
