The Laws of Motion

A push or pull on an object by another object that is touching it

• noncontact force

• contact force

• weight

• mass

a push or pull on an object

• weight

• mass

• inertia

• force

force that resists the motion of two surfaces that are touching

• friction

• contact force

• inertia

• net force

attractive force that exists between all objects that have mass

• gravity

• noncontact force

• reference direction

• static electricity

amount of matter in an object

• height

• weight

• mass

• voplume

A force one object can apply to another object without touching it

• inertia

• contact force

• noncontact force

• net force

something important; momentous

• significant

• static

• reference

• inertia

at rest or having not motion

• contact force

• unbalanced force

• inertia

• static

gravitational force exerted on an object

• weight

• mass

• volume

• density

combined forces form a net force of zero

• unbalanced forces

• balanced forces

• reference direction

• contact force
