unbalanced forces

Forces that cause a change in the motion of an object

net force

The sum of all forces acting on an object

Newtons

The unit of measurement for force

gravitional force

the force that keep objects from floating off into space

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
