Velocity is...

• the amount of time it takes from the object to move from point A to B.

• the rate an object moves.

• the rate an object moves in a certain direction, in relation to the reference point.

• an object speeding up or slowing down.

In the picture, the dot represents a car moving at a constant speed and the arrows represent the forces acting on the car.

How can the forces acting on the car be described?

• The mass must have changed.

• No force is being applied to the mass.

• The object is moving on its own. 😲
