What does the area under a velocity vs. time graph represent?

• Acceleration

• Work

• Displacement

• Power

Which force diagram best represents an object moving to the right with constant speed?

• A larger rightward force than leftward force

An object accelerates uniformly. What does the slope of the velocity vs. time graph tell us?

• Force

• Mass

• Acceleration

• Power

A velocity vs. time graph has a horizontal line at a nonzero value. What can you conclude?

• Acceleration is constant

• The object is at rest

• The object is moving with constant velocity

• Force is increasing

An object thrown upward has a velocity vs. time graph that (down is negative):

• Is a straight line with negative slope

• Is flat and horizontal

• Curves upward

• Curves downward

On an energy bar chart for a spring system with no external forces, how would the kinetic and potential energies behave?

• They would decrease only

• They would increase only

• Total energy will be constant, so they will trade off at different parts of the motion

• Total energy will be constant, so both bars will be at a maximum value at all times
