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

What unit do we measure force in?

• Kilometer/hr

• Joules

• Seconds

• Newtons

What is force?

• A push on an object

• A pull on an object

• A push or pull on an object

Since Force = Mass * Acceleration, how would you manipulate the equation to solve for mass?

• Divide both sides of the equation by Mass
• Divide both sides of the equation by force
• Divide both sides of the equation by acceleration
• Equations cannot be manipulated
