Force = Mass x Acceleration
If a 600kg racing F1 car crashes into the barrier at 85m/s (190mph)
and it takes 3 seconds for the car to stop still
What is the force that the car hit with?
First work out the acceleration:
85m/s divided by 3s
Acceleration = 28m/s/s
F = MA
Force = 600kg x 28m/s/s
Force = 16,800kN (kiloNewtons)
Force is measured in Newtons (N)
1 Newton is about the weight of an apple
Mass is mesured in Kilograms (kg)
Acceleration is measured in metres per second per second (m/s/s)
