The force the 2 surfaces exert on each other as they rub against each other
What is friction
100
Newton's 1st Law of Motion
What is: an object at rest will stay at rest, and an object in motion will stay in motion, unless acted on by an unbalanced force.
100
Newton's 3rd Law
What is: for every action, there is an equal & opposite reaction.
(Also, "Whenever 1 object exerts a force on a 2nd object, the 2nd object exerts a force back on the first object")
100
Objects falling through air experience this type of fluid friction, which specifically effects paper or feathers.
What is air resistance
200
Force is measured in
What is Newtons
200
DAILY DOUBLE! Name the 4 types of friction
What is static, sliding, rolling, & fluid
200
The resistance to a change in motion
What is inertia
200
What is the momentum of a parked car?
What is zero
200
The force of gravity on a person, based on their mass
What is weight
300
The total amount of forces acting on an object
What is Net Force
300
The measure of the amount of matter in an object
What is mass
300
The law that states that acceleration depends on the object's mass and the net force acting on the object.
What is Newton's 2nd Law of Motion
300
The law that states that the total momentum of objects that interact does not change
What is the Law of Conservation of Momentum
300
The type of force that causes a change in the object's motion.
What is Unbalanced Force
400
The force that does not change the object's motion
What is balanced force
400
The force that pulls objects closer together, specifically down.
What is gravity
400
The formula for acceleration (based on Newton's 2nd Law)
What is: Acceleration = Net Force / Mass
400
Newton's 3rd law states that for every action, there is an equal and opposite reaction. This law states that forces
What is: come in pairs
400
When an object is thrown out, or horizontally.
What is projectile
500
Force is described by
What is strength & direction
500
The strength of the forces of friction depends on these 2 factors:
What is: how hard the surfaces push together & the types of surfaces involved
500
Why Newton's 1st Law of Motion is sometimes called the "Law of Inertia"
What is: Inertia is the measure of an object's tendency to resist change in motion, a statement that has the same meaning as Newton's 1st Law
500
The momentum of an object depends on its _________ and it _________
What is mass & velocity
500
When the forces acting on an object are balanced, the net force on the object is
