What is Newton's first law

• Action-reaction

• F=MA

• inertia

• D= M/V

What are Newton's laws

• acceleration, speed

• Inertia, F=MA, action-reaction

What is the definition of Newton's third law

If you have a hockey puck sliding along a table, it will eventually come to a stop. Which Newtons laws is the example describing?

• Newtons 1st law

• Newtons 2nd law

• Newtons third law

• All of the Above

How does Newtons third law explain how a rocket takes off?

• The rocket’s acceleration is positive, while the gasses acceleration is negative but the direction is the same.

• The hot gasses move in one direction, while the rocket moves in the opposite direction but with equal force.

• The rocket is at rest until ignition.

A car has a mass of 750kg. What force is acting on the car if its acceleration is 6m/s.

• 300kg

• 4500n

• 96n

• 5m/s
