"What is the equation involving force
mass and acceleration"
A car has a mass of 2000 kg and is accelerating at 4m/s2 what is the force provided by the engine?
F= MA F = 2000x4 = 8000N
A lorry has a mass 12000 kg and the engine provides a force of 48000N what is its acceleration?
F= ma a=F/m= 48000/12000 = 4m/s2
Momentum =
Mass x velocity
Kinetic energy =
1/2* m * v2
