• Mass
• Inertia
• Gravity

What kind(s) of objects have inertia?

• all objects with mass
• only objects at rest
• only objects in motion
• only objects whose motion is being changed

An object in motion will stay in what kind of motion as long as the net forces acting on it are zero?

• slowing motion in a straight line
• accelerating motion in a straight line
• constant motion in a straight line
• constant motion in an unpredictable direction

What is Newton's First Law

• F=ma
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion. 
• Friction 

One object has twice as much mass as another object. The first object also has _ as much inertia.

• half

• three times

• twice

• four times

Does not cause a change in motion

• Balanced
• Unbalanced

What is inertia?

• the force that opposes motion
• the force of attraction between 2 objects
• an object's tendency to stay in motion or to stay at rest
• a change in an object's speed and/or direction

• Ant

Which type of force(s) will cause a change in an object's motion?

• gravity
• zero net force
• balanced forces
• unbalanced forces

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• accelerate.
