• Time

On a velocity-time graph, the slope is the

• Acceleration

• Velocity

• Position

• Time

The area under the line of a velocity-time graph represents the

• Velocity

• Acceleration

• Displacement

• Position

A triangle (∆) in physics means

• Change in

• Initial

• Final

• Velocity

What is the correct formula for acceleration?

• ∆v/∆t

• (v0 - vf)/(t0 - tf)

• ∆d/∆t

• ∆t/∆v

Negative acceleration is

• Slowing down

• Speeding up

• In the - direction

• In the + direction

If an object is moving in the + direction, and acceleration in the + direction, it is described as

• Speeding up

• Slowing down

• Staying the same speed

• Turning

Which of the following is true about directions in physics?

• You must be consistent

• Directions are arbitrary

• Using general conventions help

• All of the above
