What is displacement?

• Change in position

• Change in velocity

• Change in acceleration

• Change in time

What is instantaneous velocity?

• Average velocity over a short time interval

• Average velocity over a long time interval

• Velocity at a specific point in time

• Acceleration at a specific point in time

How do you calculate average acceleration?

• Δv / Δt

• Δx / Δt

• v / t

• a / t

What is free fall?

• Motion under friction

• Motion under gravity

• Motion under constant acceleration

• Motion under zero acceleration

How do you calculate velocity using integration?

• v = dx/dt

• v = ∫x dt

• v = ∫a dt

• v = x / t

What is projectile motion?

• Motion under constant acceleration

• Motion under friction

• Two-dimensional motion under gravity

• Motion under gravity

How do you calculate time of flight for a projectile?

• t = v / g

• t = v / (2g)

• v^2 / (2g)

• t = 2v / g

What is circular motion?

• Motion in a straight line

• Motion in a circle (uniform / non uniform)

• Motion under constant acceleration

• Motion under zero acceleration

How do you calculate centripetal acceleration?

• a = v^2 / r

• a = v / r

• a = r / v

• a = r^2 / v

What is relative velocity?

• Velocity of an object with respect to another object

• Velocity of an object with respect to the ground

• Velocity of an object with respect to time

• Velocity of an object with respect to acceleration
