if the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continue to move in a straight line with constant speed
What is Newtons 1st law
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
exists between any two objects that have mass. Attracts and pulls object towards each other.
What is gravity
200
the speed and direction of a moving abject
What is velocity
200
the acceleration of an object equal the net forced divide by the mass and is in the direction of the net force.
What is newtons second law
200
slows down an object that slides
What is sliding friction
200
push or pull
What is force
200
When air resistance balance the force of gravity, the object falls at a constant speed called the terminal velocity
What is terminal velocity
300
object is the of the gravitational force force exerted on an object
What is weight
300
Force always act in equal but opposite pairs.
What is newtons 3rd law
300
when an object rolls across a surface.
What is rolling friction
300
net is forced to zero
What is unbalance forces
300
the point in an object that moves as if all the object’s mass were concentrated at the point
What is center of mass
400
The tendency of an object to resist a change in its motion
What is inertia
400
if the net force acting on an object is zero, the object remains at rest, or if the object is already moving, continue to move in a straight line with constant speed
What is Newtons 1st law
400
Caused by the attraction between atoms on the surface that are in contact
What is static friction
400
two or more forces exerted on an object
balanced forces
400
The change in velocity divided by the time over which the change occurred
What is acceleration
500
is the amount of matter in an object
What is mass
500
the acceleration of an object equal the net forced divide by the mass and is in the direction of the net force.
