Reference: AQA
A measure of how difficult it is to change the velocity of an object, including speeding up, slowing down or changing direction.
A measure of how hard it is to change an object's velocity, defined as the ratio of force to acceleration, m = F ÷ a.
The ratio of force over acceleration, so m = F ÷ a.
