If you are moving at a constant velocity, can you feel any motion?

• 
  Yes, because balanced forces require movement.

• No, because there is no change in acceleration

• 
  

  No, because you cannot move at a constant velocity.

• 
  Yes, because you can feel like you're moving when riding in a car.

Can an object have a negative acceleration?

• 
  Yes, it means that an object is slowing down.

• 
  No, acceleration means speeding up so it must be positive.

• Yes, but it depends on if the object is going uphill or downhill.

Velocity describes which two things about an object's motion?

• Speed and Direction

• Momentum and Mass

• Acceleration and Mass
