Motion
the location of an object.
What is its position?
a graph that shows data as a line grid.
What is line graph?
a push or pull.
What is force?
a force that pulls objects down
What is gravity?
Where is the potential and kinetic energy in a roller coaster?
Potential is highest at the top, kinetic is highest at the bottom
a change in an object's position.
What is motion?
a graph's horizontal line.
What is x-axis?
False
a force that opposes motion between two objects (ex. rubbing hands together)
What is friction?

Answers will vary ; location
the information you need in order to find an objects speed.
What is distance and time?
is the amount of matter that makes up an object.
What is mass?
Give an example of a surface that would have less friction
What is icy roads, smooth tile, wood etc.
A man is about to step off the porch, what type of energy does he have?
What is potential energy
What is force?
a graph's vertical line.
What is y-axis?
What is inertia?
the law that says an object stays in motion until an outside force stops it or an object stays at rest until something makes it move
Describe what happens when someone uses brakes on a bike
Friction between the brakes and the wheels causes the bike to slow down
List the definitions for the two types of energy
Potential - stored energy ; Kinetic - energy of motion
a measure of how far an object travels in a certain amount of time.
What is speed?
What are all the parts of a graph?

Two boxes are pushed across a room, box A and box B. Box B requires more force to push it across the room. Which box has a greater mass?
What is box B.
Give an example of a surface that would have more friction
Thick carpet, sandpaper etc.
Describe the potential and kinetic energy in a swing.
Potential is greatest when the person swings backwards and stops for a split second at the top, kinetic is the greatest when the swing is coming down, moving at full speed
