Graphs
On a velocity vs. time graph, what does the area under the graph represent?
acceleration
The strength/force that something has as it continues to move as time passes
Momentum
Is Ff greater than or equal to uFn or less than or equal to uFn?
Ff greater than
Tendency of an object to resist changes in its state of motion
inertia

What does negative velocity mean on a velocity vs time graph?
the object is moving backwards or in the negative direction

What kind of graph would you use to find impulse (change in momentum)?
Force vs Time graph
What law states that forces always come in pairs that are equal in magnitude and opposite in direction?

For a pendulum, if the graph is showing a good linear fit, then what kind of graph is it?
period squared vs. length of a pendulum
Define simple harmonic motion
when the force on a moving object is directly proportional to the object’s displacement magnitude (and it acts towards the object’s equilibrium position)
What are 3 different equations to find Power?
