What does it mean if an object has a negative acceleration?

• It is speeding up

• It is slowing down

• It is moving at a constant speed

• It is stationary

What is the term used when an object accelerates at the same rate over time?

• Constant acceleration

• Non-uniform acceleration

• Instantaneous acceleration

• Variable acceleration

Which unit is used to measure distance in the second acceleration equation?

• Meters per second

• Meters

• Seconds

• Meters per second squared

When should you use the second acceleration equation instead of the first?

• When time is given

• When acceleration is given

• When distance is given

• When velocity is given

If an object starts from rest, what is its initial velocity (u)?

• Equal to its final velocity

• Equal to its acceleration

• Zero

• Equal to the distance traveled
