A change in an object's position is called ______.

• Speed

• Motion

• direction

• Friction

What is Newton's First Law

• the object at rest will always move

• Every action has an equal and opposite reaction

• An object at rest stays at rest, an object in motion stays in motion.

• Friction

A moving object will keep ________ unless acted on by an unbalanced force.

• at rest

• moving

• in one spot

• inertia

What is the other name of newton first law?

• law of motion

• law of inertia

• law of force

• law of action/ reaction

. If an object is moving at a set speed and in a set direction it will remain at that same ____

• none

• force

• motion

• velocity

is this an example of first law of motion?

• yes

• no

• don't know

Which of the following best describes Newton's first law of motion?

• B) An object will remain at rest unless acted upon by an external force

• C) An object will move with constant velocity if no net force acts upon it

• D) An object's momentum will change if no external forces are present

• A) Density

• B) Inertia

• C) Volume

• D) Elasticity

The tendency of an object to resist a change in its motion

• acceleration
• inertia
• mass
• frame of reference

What kind(s) of objects have inertia?
