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

• Yes, because balanced forces require movement.

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

• No, because there is no change in acceleration.

• No, because you cannot move at a constant velocity.

Can an object have a negative acceleration?

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

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

• No, only speed can be negative.

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