• Both magnitude and direction changes

Change in velocity is _____ in an inertial frame

• Instant

• constant

• Varying

• absolute

Acceleration =

• Acceleration = Change in Velocity / Time

• Acceleration = (Initial Velocity + Final Velocity) / 2
• Acceleration = Mass x Force
• Acceleration = Distance / Time

Acceleration is a _______

• scalar quantity
• vector quantity
• constant value
• static measurement

Average acceleration =

• Average Acceleration = (Final Velocity + Time) / Initial Velocity
• Average Acceleration = (Initial Velocity - Final Velocity) * Time
• Average Acceleration = (Final Velocity - Initial Velocity) / Final Time - Initial Time
