States that if the net force acting on an object is zero, the object will remain at rest or move in a straight line with a constant speed.
What is Newton's First Law
100
Force that acts to oppose sliding between two surfaces that are touching.
What is Friction
100
A push or pull
What is Force
100
Amount of matter in an object
What is Mass
100
States that an object acted upon by a net force will accelerate in the direction of the force, and that the acceleration equals the net force divided by the object’s mass.
What is Newton's Second Law
200
Combination of all forces acting on an object
What is New Force
200
Due to the microscopic roughness of two openers, the surfaces tend to stick together where they touch. The bonds between the surfaces are broken and form again as the surfaces slide past each other.
What is Sliding Friction
200
Two or more forces acting acting on an object that do not cancel, and cause the object to accelerate
What is Unbalanced Forces
200
Tendency of an object to resist a change in its motion
What is Inertia
200
states that forces always act in equal but opposite pairs
What is Newton's 3rd Law
300
The speed and direction of a moving object
What is Velocity
300
Occurs when an object rolls across a surface
What is Rolling Friction
300
Two or more forces whose effects cancel each other out and do not change the motion of an object.
What is Balanced Forces
300
occurring continuously over a period of time
What is Constant
300
when air resistant balances the force of gravity, the object falls at a constant speed
What is Terminal Velocity
400
Equals the change in velocity divided by the time for the change to take place; occurs when an object speeds up, slows down, or turns
What is Acceleration
400
Caused by the attraction between the atoms on the two surfaces that are in contact
What is Static Friction
400
The size of the gravitational force exerted on an object
What is Weight
400
Point in a object that moves as if all of the object’s mass were concentrated at that point.
What is Center of Mass
400
Who is the name of the person that made all 3 laws?
What is Isaac Newton
500
When air resistant balances the force of gravity, the object falls at a constant speed
What is Terminal Velocity
500
The force that causes Earth to orbit the Sun and the Moon orbit Earth
What is Gravity
500
The net force on an object when it moves in a circular motion.
What is Centripetal Force
500
The speed and direction of a moving object
What is Velocity
500
If two people were both pulling a door, what force would that be?
