Physics Exam Review Q1

What is the correct unit for distance in kinematics?

• m

• ft

• mi

• km

What is the correct unit for velocity in kinematics?

• m/min

• mi/hr

• d/t

• m/s

What is the correct unit for acceleration in kinematics?

• m/s

• m/min²

• m/s/t

• m/s²

When an object starts from rest, what is its original velocity?

• Depends on the problem

• 0

• Always positive

• Always negative

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

• Depends on the problem

• 0

• Always positive

• Always negative

A change in velocity over time is known as:

• acceleration
• constant speed
• average speed
• displacement

What is this graph representing?

• Constant Speed
• Acceleration (speeding up)
• Deceleration (slowing down)
• No motion

What two measurements are necessary for calculating speed?

• Mass and time
• Temperature and mass
• Mass and distance
• Distance and time

What is the formula to calculate speed?

• S = t/d
• S = d/t
• S = d x t
• S = t x d

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object
