net force

The force that opposes the motion of objects. For example, this force pushes back on you when you walk forward

friction

For every action there's an equal and opposite reaction

3rd

You need a force to accelerate an object that has mass

2nd

m = F/a 10000/2 = 5000 g

How fast would a 3g toy car accelerate if it was pushed wit 30N of force?

a = F/m 30/3 = 10 m/s^2
