Newton's 2nd Law

What unit do we measure force in?

• Kilometer/hr

• Joules

• Seconds

• Newtons

What is Newton's 2nd Law?

• Every action has an equal and opposite reaction

• An object at rest stays at rest, an object in motion stays in motion.

• Force is dependent on the mass and acceleration of an object.

• Friction
