Newton's Laws & Forces Review

When an unbalanced force acts on an object, the force ______________________.

• changes the motion of the object

• is cancelled by another force

• does not change the motion of an object

• is equal to the weight of the object

According to Newton’s Second Law of Motion, force is equal to mass times ______________________.

• inertia

• weight

• acceleration

• direction

The picture is an example of Newton's

• 1st Law.

• 2nd Law.

• 3rd Law.

Any push or pull on an object is a(n)

• force.

• velocity.

• inertia.

• momentum.

When all the forces on an object are equal and opposite, the net force is zero. This means that forces are

• balanced.

• unbalanced.

• reactive.

The combination of all the forces acting on an object is

• net force.

• action force.

• reaction force.

• balance force.

What is Newton's First Law of Motion?

• F = ma

• An object at rest stays at rest unless acted on by an unbalanced force.

• For every action there is a equal and opposite reaction.

• An object in motion remains in motion unless acted on by an unbalanced force.

What is Newton's Second Law of Motion?

• An object at rest remains at rest unless acted on by an unbalanced force.

• Force = mass x acceleration

• For every action there is a equal and opposite reaction.

• An object in motion remains in motion unless acted on by an unbalanced force.

Which of Newton's Laws of Motion is represented by this picture?

• Newtons 2nd Law of Motion

• Law of Gravity

• Newtons 1st Law of Motion

• Newtons 5th Law of Motion

What is the tendency of an object to resist a change in motion?

• coffee
• motion
• inertia
• gravity
