Woody drove his race car. He slowed down and turned toward the pit lane. The most correct type of motion is
speed
velocity
acceleration
at rest
In the distance versus time graph such as the one pictured, a straight line means
the speed was increasing
the speed was decreasing
the speed was constant
the object was at rest

velocity
Predict what will happen if the pairs pull with force shown in the picture?
Balance forces will not allow the flag to move
The pair pulling with 12N of force will move the flag to their side
The pair pulling with 10N of force will move the flag to their side
The forces will cancel each other out the flag will not move
The best example of a balanced forces is

We wear seat belts in cars because _________ will cause us to move forward in a crash.
mass
speed
inertia
The more mass an object has, the _______ force it takes to accelerate it.
more
