Inertia is often referred to as:

• an object's ability to resist motion
• Newton's First Law of Motion
• an object's ability to resist stopping once in motion.
• All of the above

The opposition to motion between to objects in contact is known as:

• unbalanced force
• gravity
• friction
• balanced force

Acceleration can be described as:

• change in speed
• objects traveling faster or slower
• a change in velocity
• a change in velocity over time
