• the object accelerates

• the weight decreases

• the motion stays the same

Friction is a force that

• opposes an objects motion

• decreases with larger mass

• does not exist when surfaces are very smooth

Forces in the same direction add together. Forces in opposite directions subtract from one another. The net force is the overall force acting on an object.
