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

• Depends on the problem

• 0

• -9.8m/s²

• Always positive

If an object starts comes to a stop, what is its final velocity?

• Depends on the problem

• 0

• -9.8m/s²

• Always positive

In a Kinematic problem if you are asked to find how far you are solving for the magnitude of

• displacement (Δx)

• initial velocity (v₀)

• final velocity (v)

• acceleration (a)

• time (t)

In a Kinematic problem if you are asked to find the speed at the end of the motion you are solving for the magnitude of

• displacement (Δx)

• initial velocity (v₀)

• final velocity (v)

• acceleration (a)

• time (t)

In a Kinematic problem if you are asked to find the speed at the beginning of the motion you are solving for the magnitude of

• displacement (Δx)

• initial velocity (v₀)

• final velocity (v)

• acceleration (a)

• time (t)
