Acceleration

The rate at which velocity changes, measured in metres per second squared (m/s²).

The rate at which velocity changes, measured in metres per second squared (m/s²).

A change in velocity, which can be a change in speed, direction, or both.

The rate at which an object's velocity changes, measured in metres per second squared ($\text{m/s}^2$).

The rate at which velocity changes, calculated by dividing the change in velocity by the time taken; its unit is metres per second squared, m/s².

The rate of change of velocity, measured in metres per second squared (m/s²).

A change in velocity per unit time; changing direction counts as acceleration even if speed is unchanged.

The change in velocity per unit time. Acceleration can involve a change in speed, direction, or both.

The rate at which velocity changes; it is measured in metres per second squared ($\text{m/s}^2$).

The rate at which velocity changes, measured in metres per second squared (m/s²).

The rate at which velocity changes. A change in direction therefore counts as acceleration, even when speed remains constant.

The rate at which velocity changes, measured in metres per second squared ($\text{m/s}^2$).

The rate at which an object's velocity changes, measured in metres per second squared (m/s²).

The change in velocity per unit time: $a = \frac{v-u}{t}$. Its unit is m/s².

A change in velocity per unit time; changing direction counts as acceleration even when speed is constant.

The rate at which speed changes, measured in metres per second squared (m/s²).

The change in velocity per second, measured in m/s².
