“Ball C" is rolling across the surface, but it eventually comes to a stop. Which force is most likely responsible for this?

• gravity
• friction
• electricity
• magnetism

An identical object was placed onto the three different surfaces and set into motion with an identical force. The bars show how far it took the object to travel 10 meters. Based on the graph, which surface had the greatest friction?

• surface A
• Surface B
• Surface C
• Friction is the same on every surface

Which of the following might explain why the object on Surface A traveled the fastest?

• it was the roughest surface
• it was the only surface that sloped upward
• it had more surface area touching the object than the other surfaces
• it was the only surface that was lubricated

If the forces are the same in Scenario A and Scenario C, which ball would move the fastest?

• both balls would move at the same speed
• there is no way to determine which ball would move the fastest
• the ball in Scenario C
• the ball in Scenario A

What happens when 2 equal forces act on an on an object in the same direction.

• no movement; won't move
• object will move in the direction of the force
• Object will move in the opposite direction of the force
• Object flies

Ball B" is moving towards the rectangular block. Which feature of the block can explain why this is happening?

• the block is blowing air towards "Ball B"
• the block is a magnet (and "Ball B" is made of a magnetic material)
• the block is located on the highest part of the surface
• the block is heavier than "Ball B"

What happens when 2 equal forces act on an object in opposing directions?

• no movement; won't move
• Object will move in the direction of the force
• Object will move in the opposite direction of the force
• the object flies

If Block B and Block D are the same mass, which of the following describes how they would move when exposed to the forces above?

• Both blocks would move in the same direction, but at different speeds.
• Both blocks would stay still.
• Both blocks would move in the same direction and at the same speed.
• Both blocks would move at the same speed, but in different directions.

This force attracts all objects toward each other.

• Newton
• gravity
• weight
• path

How is motion affected when forces are balanced acting on an object?

•  Keep an object moving at the same speed.
•  Keep an object at rest or not moving
• Both options
• Neither option
