F = ma lets us work out the forces at work on objects
by multiplying the mass of the object by the acceleration of the object. Example:
The force at work on a Formula 1 car as it starts a race!
If the F1 car has a Mass of 600kg and an Acceleration of 20m/s/s
then we can work out the Force pushing the car by multiplying
the Mass by the Acceleration like this 600 x 20 = 12000N
F = ma is the second law of motion proposed by Sir Isaac Newton.
