The steeper the line, the _______ the object is moving.
The more gently sloping the line, the ________ the object is moving.
faster ; slower

Blaiklee and Anna are playing tug-a-war. The rope is not moving, what is the net force of the forces acting on the rope?
Zero Net Force (forces are balanced)
300
any push or pull
Force
300
The more massive the object, the _______ the force needs to be.
Greater

Jeylin and Reyna are testing to see what surface will allow them to ride on their bikes faster. Based on your knowledge of friction, would they ride faster on carpet or ice?
Faster on ice, because it is smooth (has less firction opposing force)
400
A force that acts to oppose the motion of an object (this slows the object down)
Friction
400
Something with a lot of ________ is hard to stop or start moving.
Inertia
400
Stored Energy - A rubber band that has been stretched as far as it will go
Potential Energy
400
What kind of line shows the change of direction (moving back towards starting point)?
A line sloping down.

Logan and Jesse are playing with toy cars. Jesse's car is not moving and Logan's car is moving fast towards Jesse's car. When Logan's car collides with Jesse's car, what will happen to Jesse's car?
Energy of Logan's car with transfer with Jesse's car causing it to start moving and change its direction.
500
The combination of all forces acting on an object.
Net Force

Mrs. Sparks' car broke down. She tried pushing the car, but it wouldn't move. Her husband got out of the car and helped her. Together they were able to push the car to the side. Why wasn't Mrs. Sparks able to move the car by herself?
The car has a lot of mass. This means you need more force to move it. Together, Mrs. Sparks and her husband had more force and were able to move the car.
