describes how an object moves when the net force acting on it is zero
What is Newton’s 1st Law
100
the size of the gravitational force exerted on an object
What is Weight
100
the change in velocity divided by the time over which the change occurred
What is Acceleration
200
occurs when an object rolls across a surface
What is Rolling Friction
200
due to gravity between the satellite and Earth
What is Centripetal Force
200
connects the net force on an object, its mass, and its acceleration
What is Newton’s 2nd Law
200
the tendency of an object to resist a change in its motion
What is Inertia
200
when air resistance balances the force of gravity, the object falls at a constant speed
What is Terminal Velocity
300
occurs when an object rolls across a surface
What is Rolling Friction
300
the combination of all the forces acting on an object
What is Net Force
300
describes something else that happens when one objects exerts a force on another object
What is Newton’s 3rd Law
300
the speed and direction of a moving object
What is Velocity
300
the amount of matter in an object
What is Mass
400
it prevents an object from moving when a force is applied
What is Static Friction
400
Two or more forces exerted on an object
What is Balanced Forces
400
describes how an object moves when the net force acting on it is zero
What is Newton's 1st Law
400
the force that pulls you down and causes Earth to orbit the sun
What is Gravity
400
The net force is not zero
What is Unbalanced Forces
500
it prevents an object from moving when a force is applied
What is Static Friction
500
The net force is not zero
What is Unbalanced Forces
500
connects the net force on an object, its mass, and its acceleration
What is Newton's 2nd Law
500
A theoretical or experimental quantity, condition, or factor that does not vary in specified circumstances. Avogadro's number and Planck's constant are examples of constants.
What is Constant
500
the point in an object that moves as if all the object’s mass were concentrated at that point
