100
The force that brings nearly everything to a stop.
What is Friction?
100
The combination of all the forces acting on an object.
What is Net Force?
100
Forces always act in equal but opposite pairs.
What is Newton's 3rd Law
100
The amount of matter in an object.
What is Mass
100
Occurs any time an object speeds up, slows down, or changes its direction of motion.
What is Acceleration?
200
Slows down an object that slides.
What is Sliding Friction?
200
A push or a pull
What is Force?
200
How an object moves when the net force acting on it is zero. If the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with constant speed.
What is Newton's 1st Law?
200
The speed and direction of a moving object.
What is Velocity?
200
The force that attracts a body toward the center of the Earth.
What is Gravity?
300
Occurs when an object rolls across a surface.
What is Rolling Friction?
300
When the net force is not zero.
What is Unbalanced Forces?
300
When forces are equal but in opposite pairs.
What is Newton's 3rd Law
300
Occurring constantly over a period of time.
What is Constant?
300
When air resistance balances the force of gravity, the object falls at a constant speed.
What is Terminal Velocity
400
Caused by the attraction between the atoms on the two surfaces that are in contact.
What is Static Friction?
400
When two or more forces exerted on an object.
What is Balanced Forces?
400
Connects the net force on an object, its mass, and its acceleration. The acceleration of an object equals the net force divided by the mass and is in the direction of the net force.
What is Newton's 2nd Law?
400
An object is the size of the gravitational force exerted on an object.
What is Weight?
400
The point in an object that moves as if all the object’s mass were concentrated at that point.
What is Center of Mass
500
Name 2 types of Friction
What is Sliding Friction, Rolling Friction, or Static Friction?
500
When an object moves in circular motion, the net force on the object is called circular motion.
What is Centripetal Force?
500
How an object moves when the net force acting on it is zero. If the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with constant speed.
What is Newton's 1st Law?
500
The tendency of an object to resist a change in its motion.
What is Inertia?
500
How heavy you are.
What is Weight?
