Newton's laws of motion

An object at rest will stay at rest unless an unbalanced force acts on it.

• True

• False

If an object in motion is not acted on by an unbalanced force, it will continue with the same speed and direction.

• True

• False

The tendency of an object to resist change in motion.

• Force

• Motion

• Friction

• Inertia

Lighter objects have LESSER inertia than heavier objects.

• True

• False

An object will remain at rest or in uniform motion in a straight line unless acted upon by an external force.

• Newton's First Law of Motion

  
  

• Newton's Second Law of Motion

• Newton's Third Law of Motion

• Newton's Fourth Law of Motion

It is also called the Law of Inertia.

• Newton's First Law of Motion

• Newton's Second Law of Motion

• Newton's Third Law of Motion

• Newton's Fourth Law of Motion

Because of inertia, a resting object ________.

• will remain at rest

• will move at a constant speed

• will eventually move

• is unbalanced

Newton's second law of motion states that force is equal to mass times:

• acceleration

• force

• motion

• inertia
