The image shows a rocket and a skateboard moving. What can be concluded about the forces experience by the rocket?

• The action force cancels out the reaction force.

• The action force is greater than the reaction force.

• The action and reaction forces act on the same object.

• The action force has an equal and opposite reaction force.

Velocity

• the speed of an object in a given direction

• the path that an object is moving or facing

• a change in an object's speed or direction; example: if a car is turning or speeding up

• the rate at which an object moves; depends on distance and time traveled
