• cruising speed

The total distance traveled divided by the total time of travel.

• instantaneous speed
• average speed
• constant speed
• velocity

Speed and direction of motion.

• velocity
• acceleration

The rate of change in velocity

• speed
• acceleration
• force
• motion

A push or pull one body exerts on another.

• force
• motion
• speed
• inertia

Forces that are equal in size but opposite in direction. (Equal zero)

• net force
• friction
• balanced force
• inertia

When the velocity of an object changes and the object accelerates in the direction of greater force.
