The concept you are describing is known as **work** in physics. Work is defined as the transfer of energy that occurs when a force is applied to an object, causing it to move a certain distance in the direction of the force. The formula for calculating work (W) is:
\[ W = F \times d \times \cos(\theta) \]
where:
- \( W \) is the work done,
- \( F \) is the magnitude of the applied force,
- \( d \) is the distance over which the force is applied, and
- \( \theta \) is the angle between the force and the direction of motion.
If the force is applied in the same direction as the motion, \( \theta \) is 0 degrees, and \( \cos(0) = 1\), so the formula simplifies to \( W = F \times d \). Work is measured in joules (J) in the International System of Units (SI).
