net force
The sum of all forces acting on an object
Newtons
The unit of measurement for force
gravitional force

Frictional Force
the forces that oppose the motion of objects as they move past each other
normal force
the perpendicular contact force exerted by a surface on another object
free body diagram
a diagram showing all the forces acting on an object
Applied Force
a force that is applied to an object by a person or another object
Force
a push or pull on an object; measured in Newtons (N)
balanced forces
forces acting on an object that combine and form a net force of zero
