Newton's 2nd Law

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.

• F = ma

• Friction

If the man pushes with an equal amount of force, which object will accelerate more?

• Car because it has more mass

• Lawnmower because it has less mass

• Car because it has less mass

• Lawnmower because it has more mass
