Term
SI unit to measure force
Definition
newton
Term
states that every object in the universe pulls on every other object; the more mass and object has the greater its gravitational force; the greater the distance between two objects, the less attraction they have for each other
Definition
newton's law of gravity
Term
states that an object in motion remains in motion and an object at rest remains at rest unless acted upon by an outside force
Definition
newton's first law of motion
Term
also known at the law of inertia
Definition
newton's first law of motion
Term
acceleration of an object increases as the amount of force causing the acceleration increases
Definition
newton's second law of motion
Term
for every action there is an equal and opposite reaction
Definition
newton's third law of motion
Term
any push ot pull exerted on an object that could result in an acceleration
F=ma
Definition
force
Term
a change in speed and/or direction; a change in velocity
Definition
acceleration
Term
speed in a definite direction
Definition
velocity
Term
a force applied to an object over a distance; work equals force multiplied by distance
(W = F x D)
Definition
work
Term
energy of an object as a result of its position
Definition
potential energy
Term
energy possessed by an object because it is in motion
Definition
kinetic energy
Term
unit of work which is equal to one newton-meter
Definition
joule
Term
tendency of an object to resist changes in motion
Definition
interia
Term
also known as newton's first law of motion
Definition
interia
Term
the force of attraction that pulls things toward each other
Definition
gravity
Term
a force that acts to slow down the relative motion of objects
Definition
friction
Term
a device that decreases the amount of force necessary to move an object by changing the direction of the applied force, making wirk easier
Definition
machine
Term
an indirect measure of the friction that slows the movement of charges through a circuit
Definition
resistance
