In the video example that just played, what was the unbalanced force that acted on the soccer ball and caused it to move?

• gravity

• the force of the player's foot

• the normal force

What science word means that an object resists changing what it is doing? (In other words, this word means that an object stays still or stays moving, unless a force acts on it.)

• gravity

• momentum

• inertia

• acceleration

What force eventually stops a rolling ball from moving forward?

• momentum

• friction

• gravity

• a reaction force

What is the impact of air resistance​?

• It speeds up the motion of objects in the air.

• It reduces the impact of gravity on airborne objects.

• It slows down the motion of objects in the air.

According to Newton's First Law of Motion, objects in motion tend to ___________.

• stay at rest

• accelerating

• stay in motion at the same speed
