Part D: Multiple TRUE/FALSE 4. Which of the following statements about acceleration are TRUE? List all that apply.
Acceleration is a vector quantity.
- Accelerating objects MUST be changing their speed.
- Accelerating objects MUST be changing their velocity.
- Acceleration units include the following; m/s2, mi/hr/sec, cm/s2, km/hr/m.
- The direction of the acceleration vector is dependent upon two factors: the direction the object is moving and whether the object is speeding up or slowing down.
- An object which is slowing down has an acceleration.
- An object which is moving at constant speed in a circle has an acceleration.
- Acceleration is the rate at which the velocity changes.
- An object that is accelerating is moving fast.
- An object that is accelerating will eventually (if given enough time) be moving fast.
- An object that is moving rightward has a rightward acceleration.
- An object that is moving rightward and speeding up has a rightward acceleration.
- An object that is moving upwards and slowing down has an upwards
