Prevents an object from moving when force is applied.
What is Static Friction
100
Toward the center of the object’s circular path.
What is Centripetal Force
100
Motion; if the net force acting on an object is zero, the object remains at rest.
What is Newton’s 1st law
100
the speed of something in a given direction
What is Velocity
100
The force that causes Earth to orbit the Sun and the Moon to orbit Earth.
What is Gravity
200
When an object rolls across a surface.
What is Rolling Friction
200
If the net force is not zero.
What is Unbalance Forces
200
Motion; the acceleration of an object equals the net force divided by the mass.
What is Newton’s 2nd law
200
occurring continuously over a period of time
What is Constant
200
the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.
What is Terminal Velocity
300
While static friction acts on an object at rest.
What is Sliding Friction
300
Two or more forces exerted on an object.
What is Balanced Forces
300
A force is a push or a pull upon an object that results from its interaction with another object.
What is Newton’s 3rd law
300
The size of the gravitational force exerted on an object.
What is Weight
300
The point in an object that moves if as all the object’s mass were concentrated at that point.
What is Center Of Mass
400
While static friction acts on an object at rest.
What is Sliding Friction
400
all the forces acting on an object.
What is Net Force
400
Motion; the acceleration of an object equals the net force divided by the mass.
What is Newton’s 2nd law
400
a tendency to do nothing or to remain unchanged
What is Inertia
400
increase in the rate or speed of something
What is Acceleration
500
The force that brings nearly everything to a stop.
What is Friction
500
Push or Pull
What is Force
500
Motion; if the net force acting on an object is zero, the object remains at rest.
What is Newton’s 1st law
500
a coherent, typically large body of matter with no definite shape
