Newton's Third Law States...

• Objects in motion stay in motion and objects at rest stay at rest
• Force is equal to mass times acceleration
• For each action there is an equal and opposite reaction

The gravitational pull is greater between two objects that

• have greater masses.
• have rougher surfaces.
• are farther apart.
• are moving at greater speed

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.

When a cannon fires a cannonball we observe Newton's third law. Which force is the reaction force?

• The cannon moving forward
• The cannonball moving forward
• The cannon moving backward
• The cannonball moving backward

What is the difference between mass and weight?

• mass is how much matter is in an object, and weight is the gravitational pull on that object
• mass and weight are the same
• weight affects how much mass is in an object
• weight is determined by how many atoms make up an object

The SI units of force are measured in 

• Grams
• Newtons
• Pounds
• Kilograms

What is gravitational force?

• It makes objects at rest start moving.
• It makes objects that are moving stop.
• The force of attraction between two objects.
• It pulls you into space.
