Vector Quantity
A force that opposes the motion of an object.
Friction
Balanced force
Vector quantity
Sir Isaac Newton
Two or more forces that act on an object without causing a change in the object's motion.
Balanced forces
Unbalanced forces
Static friction
Kinetic friction
A labeled drawing that explains or shows the part of something; can be a type of model.
Vector quantity
Net force
Diagram
Friction
A type of friction that occurs when force is applied to an object and the object moves.
Force
Kinetic friction
Static friction
Net force
The sum of all forces acting on an object.
Force
Balanced forces
Unbalanced forces
Net force
Unit of force in the metric system.
Kilogram (kg)
Pounds (lb)
Newton (N)
Meters per second (m/s)
Two or more forces that produce a net force on an object. This causes the object to change speed or direction (accelerate).
Unbalanced forces
Balanced forces
Net force
Vector quantity
A type of friction that occurs when the force that is applied does not cause the object to move.
Kinetic friction
Static friction
Heat friction
