Based on the graph, it can be determined that:

• Swimmer 1 and Swimmer 2 were moving in the same direction
• Swimmer 2 is faster than Swimmer 1
• Swimmer 1 and Swimmer 2 were moving in different direction
• Swimmer 1 is faster than Swimmer 2

If the graph is describing the motion of a sled, which of the following might explain why Surface A was the fastest?

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

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

• Surface B

• Surface C

• Surface A

• Friction is the same on every surface

In Scenario A, a ball is being pushed along by a large force. If the force were suddenly decreased (like in Scenario B), what would happen to the motion of the ball?

• it would speed up    
• it would remain the same
• It would slow down
• it would change direction

What is a force?

• A push or pull that can change the motion of an object

• To reach a conclusion using evidence and reasoning

• The energy that an object has because it is moving

• The amount of matter that makes up an object

How could you describe the strength of forces on two objects in a collision?

• The strength of the forces is different on each object

• The strength of the forces is the same on each object

• It depends on the objects
