What example of force is this?
(an apple falling down a tree)
Gravitational force
Is this statement true?
The term sliding friction refers to the resistance created by two objects sliding against each other.
yes, this statement is true.
Fill in the blank.
Rolling friction is the resistive force that ________ the motion of a rolling ball or wheel.
(slows down/ speeds up)
Slows down
Is this statement true?
Static friction is a force that does not keep an object at rest.
No, this statement is false.

What does Newton’s third law state?
His third law states that for every action (force) in nature there is an equal and opposite reaction.
what does Newton’s first law state?
The First Law states, "A body at rest will remain at rest, and a body in motion will remain in motion unless it is acted upon by an external force."
Is this statement true?
In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it.
Yes, this statement is true.
What is projectile motion?
Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity.

Is there a difference between vertical and horizontal motion? if there is, what is it?
There is a major difference between the vertical and the horizontal motion of a projectile. This is that the vertical motion is changing, but the horizontal motion is constant
What does Newton’s second law state?
Newton's second law of motion is F = ma, or force is equal to mass times acceleration.
