Causing Acceleration

Isaac Newton was the first to realise that to make something accelerate (speed up or slow down) we must apply a force to the object.

A larger force will lead to a larger acceleration. Similarly, if we use the same force, a larger mass (heavier) object will accelerate less - it's harder to move.

From Newton's work, we have the following relationship:

force = mass x acceleration

or

F = m x a

You may need to learn this! Let‘s take a look at an example...
