Newton's Laws

"For every action, there is an equal and opposite reaction."

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• Newton's 4th Law

Force = Mass x Acceleration

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• Newton's 4th Law

"An object in motion (or at rest) will to stay in motion (or at rest) until an outside force acts upon it."

• Newton's 1st Law
• Newton's 2nd Law
• Newton's 3rd Law
• Newton's 4th Law

The tendency of an object to resist changes in its motion is...

• inertia
• force
• acceleration
• velocity

Any push or pull on an object.

• force
• velocity 
• inertia
• momentum

A force that opposes motion between a surface in contact with the atmosphere.

• air resistance
• gravity
• momentum
• terminal velocity

A Newton is a unit of...

• force
• inertia
• acceleration
• velocity

How does Newton’s 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 rocket is at rest until ignition.
• The hot gasses move in one direction, while the rocket moves in the opposite direction but with equal force.

Calculate the net force.

• 5 N
• 10 N
• 45 N
• 500 N
