Net Force In many situations, including driving, more than one force is acting on an object. The combination of all forces acting on an object is the net force. Net force determines whether, and by how much, an objects motion is changed. Total Force
Force Diagrams Objects are shown as a rectangle or square.
Force Diagrams A push or pull (force) is shown with an arrow
Force Diagrams The arrow always points AWAY from the object.
Force Diagrams The bigger the force, the bigger the arrow
Force Diagrams Label the arrows with the magnitude (amount) of the force (in N) 10 N 3 N
Force Diagrams Net Force is the sum of all of the forces 10 N3 N 7 N
Practice: Draw an object with two forces acting in opposite directions with one force equal to 2 N and one force equal to 8 N.
Balanced vs. Unbalanced Forces If there is a situation of unbalanced forces, there is a net force. Balanced forces mean there is a net force of zero on the object. Describe the motion of the blocks below. 10 N 2 N 8 N A. B.
