Newton's first law applies

• to both moving and nonmoving objects

• only to moving objects

• only to objects that are not moving

Newton's first law is also called the Law of ...

• Friction

• Inertia

• Unbalanced forces

• Newtons

Newton's first law states that an object in motion will stay in motion unless acted on by a(n)

• balanced force

• unbalanced force

Because of inertia, a moving object will keep ________ unless acted on by an unbalanced force.

• at rest

• moving

• in one spot

• inertia

• stop moving

• change direction

• there will be no change in the object's motion

Because of inertia, a resting object will remain at ________.

• rest

• a constant speed

• school

• inertia
