Forces/Gravity/Newton's Laws Review

Is this a balanced or unbalanced force?

• balanced

• unbalanced

This picture demonstrates which of Newton's Laws of Motion?

• First Law

• Second Law

• Third Law

• Law of Gravity

Which is NOT an example of a contact force?

• Gravity

• Friction

• Air Resistance

• Push and Pull

An object at rest will stay at rest and an object in motion will stay in motion

• unless there is an equal and opposite reaction force

• if the object accelerates

• it always stays the same no matter what.

• unless it is acted on by another unbalanced force.

True or False: Mass and Weight are the same thing.

• True

• False

Which of the following is an example of a non-contact force?

• gravity

• electrical

• magnetic

• all are examples of non-contact forces

This picture is an example of which of Newton's Laws? (soccer ball at rest & kicking it)

• First Law

• Second Law

• Third Law

What is the net force AND direction of this soccer ball?

• 20N & to the right

• 80N & to the right

• 20N & to the left

• 80N & to the left

Why does weight change depending on the location in the universe?

• It never changes regardless of where you go.

• The gravitational pull allows for a change in weight

• Weight & mass are the same. Mass changes = Weight changes

• The size of the object changes everywhere you go.

How are contact and non-contact forces different.

• Both touch objects for force.

• Contact touches objects for force & non-contact does not.

• Non-contact touches objects for force & contact does not

• Both don't touch objects for force.
