The total distance traveled by on object divided by the total time.

• Average Speed
• Velocity
• Acceleration
• None of These

Forces that are equal in strength and opposite in direction that act against each other and cause an object’s motion to remain constant.

• Balanced Forces
• Unbalanced Forces
• Friction
• Motion

Force between surfaces that resists motion.

• Friction
• Air Resistance
• Balanced Forces
• All of These

A change in the position of an object

• Balanced Force
• Inertia
• All of These

The distance an object moves per unit of time, such as miles per hour

• Speed
• Velocity
• Acceleration
• All of These

Forces that are unequal in size or direction and that change an object’s motion

• Inertia

The straight-line distance between the starting and ending points.
