# PHYSics TEST

### Mrs. Eisenlord

When position changes compared to a reference point motion
Speed at one moment in time instantaneous speed
Total distance divided by total time average speed
A non-moving object used to detect if something is moving reference point
A graph that shows the motion of an object position-time graph
A push or a pull force
Most important constant force gravity
When forces are not equal and not opposite; cause changes in motion unbalanced force
When forces are equal and opposite; cannot change motion balanced force
A force that is always on an object constant force
A force that acts on an object for just a short bit of time momentary force
A force that acts in the direction opposite an object's motion friction
Stored energy potential energy
Energy that is being used kinetic energy
Heat energy thermal energy
Energy cannot be created or destroyed, but it can be _______ transformed
A line on a position-time graph that is going away from the reference point will be facing __ up
A line on a position-time graph that is moving toward the reference point will be facing ____ down
A line that means no motion will be ____ flat
What kind of line means that the speed is constant? straight
The x-axis on a position-time graph time
The y-axis on a position-time graph position
To solve an average speed problem, you use this operation division
To solve a distance problem, you use this operation multiplication
Gravity is shown in a force diagram as an arrow pointing ____ down
We show forces in diagrams as ______ arrows
Potential and kinetic are two types of ______ energy
The ______ an object is lifted, the more potential energy it has higher
If two objects are lifted to the same height, the object with more ____ will have more potential energy mass
If there are two lines on a position-time graph, the _______ one is faster steeper
