applied force

Friction slows down moving objects. ( True/ False)

False

Measured in Newtons.

weight

……………………… works in the opposite direction in which the object is moving.

friction

Why do some objects sink? An object will sink if the upthrust force acting on it is ………………........... than its weight.
