a force that holds back the movement of a sliding object
What is FRICTION
100
a push or a pull
What is force
100
if the net force acting on an objects zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with a constant speed
What is Newton's First Law
100
the speed and direction of a moving object
What is Velocity
100
force that exists among all material objects in the universe
What is Gravity
200
when two solid surfaces slide against each other
What is Sliding Friction
200
the combination of all the forces acting on an object
What is Net Force
200
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
200
ongoing, continuously
What is Constant
200
The velocity with which a body moves relative to a fluid when the resultant force acting on it
What is Terminal Velocity
300
when a solid object is rolling across a surface
What is Rolling Friction
300
if the net force is not zero
What is Unbalanced Forces
300
forces always act in equal but opposite pairs
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 as if all the object’s mass were concentrated at that point
What is Center of Mass
400
frictional force that prevents two surfaces from sliding past each other
What is Static Friction
400
Two or more forces exerted on an object
What is Balanced Forces
400
if the net force acting on an objects zero, the object remains at rest, or if the object is already moving, continues to move in a straight line with a constant speed
What is Newton's 1st Law
400
the tendency of an object to resist a change in its motion
What is Inertia
400
the change in velocity divided by the time over which the change occurred
What is Acceleration
500
a force that holds back the movement of a sliding object
What is Friction
500
net force on an object that moves in a circular motion
What is Centripetal Force
500
forces always act in equal but opposite pairs
What is Newton's 3rd Law
500
the amount of matter in an object
What is Mass
500
force that exists among all material objects in the universe
