NEWTON'S 3 LAW'S

What is Newton's First Law

• For action there is an equal and opposite reaction

• An object at rest will stay at rest, an object in motion will stay in motion unless acted upon by an outside force.

• Force=Mass x Acceleration

A 50 kg skater pushes off from a wall with a force of 200 N. What is the skater’s acceleration?

Solve this problem

• 200 / 50 = 4 m/s²

• 50 / 200 = 4 N

• 200 x 50 = 10,000 m/s²

• 200 / 50 = 4 N
