Newton's Laws

Newton's 1st Law is also called the Law of ______________________

• Friction

• Balanced forces

• Unbalanced forces

• Inertia

An object in motion tends to stay in motion unless a(n) ____________________ force acts on it.

• Balanced

• Unbalanced

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

• at rest

• moving

• in one spot

• inertia

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

• rest

• school

• constant speed

• inertia

Objects at rest remain at rest and objects traveling at a steady rate in a straight line continue that way until a _________acts on them.

• Inertia

• Force

• Velocity

• Acceleration

Why is the net force 0 in the image?

• Because the elephants are the same size

• Because they are elephants

• Because they are both pulling the same amount of force in opposite directions

• Because they are pulling away from each other

Football A has a greater mass than football B. Which football will have greater acceleration when both are thrown with the same force in the same direction?

• Football A

• Football B

• They will have the same acceleration

• The mass has no effect on acceleration

A ball is rolling on the floor and a force pushes it in the same direction, what will happen?

• The ball will go faster

• The ball will stop

• The ball will slow down

• The ball will fly in the air

What is the net force?

• 40 N left

• 400 N right

• 0 N balanced

• 40 N right

Will it take more force to push an empty shopping cart or a shopping cart that is full?

• The empty shopping cart

• The full shopping cart

• They will take the same amount of force

• Depends on what is in the full shopping cart
