Term
 force
Definition
 a push or pull on an object causing it to move, speed up, slow down, stop, or change direction can be constant speed or accelerate weight is also known as this
Term
 universal forces
Definition
 gravitational, electrical, and magnetic are 3 types of...
Term
 gravitational
Definition
 this force pulls any 2 objects toward one another example would be: stopping a swing from swinging
Term
 weight
Definition
 an object has this because the force of gravity pulls down on the object a spring scale is used to measure this...
Term
 Newtons 1st Law
Definition
 object at rest will remain at rest unless acted upon by force object in motion will remain at the same speed and direction unless acted by an outside force also known as inertia
Term
 gravity
Definition
 a force that causes something to to move it pulls objects down or pulls 2 objects towards one another
Term
 electrical
Definition
 this force pull or push forces that exists around charged particles like charges will repel - positive/positive unlike charges will attract - positive/negative
Term
 magnetic
Definition
 this force attracts iron and steel
Term
 repel
Definition
 north and north poles close together will
Term
 attract
Definition
 north and south poles close together will...
Term
 work
Definition
 the result of a force moving an object more gravity, more force will result in more of this to move an object less gravity, less force will result in less of this to move an object it is what is needed to move an object
Term
 simple machines
Definition
 their primary job is to make work easier examples include: inclined plane, wedge, pulley, wheel and axle, lever, screw
Term
 constant
Definition
 motion that does not change and is graphed with a straight line
Term
 friction
Definition
 slows the motion of moving objects produces heat energy like rubbing your hand together
Term
 kinetic energy
Definition
 energy of motion or moving examples: pushing a toy car down a ramp a child going down a slide
Term
 potential energy
Definition
 stored energy such as a vehicle parked in the garage other examples include: a toy car on the top of a ramp a book placed near the end of a table
Term
 kinetic energy
Definition
 loss of height increases this type of energy example: if a car on a ramp starts to roll, the car will begin to move faster
Term
 Newtons 3rd Law
Definition
 for every action, there is an equal and opposite reaction
Term
 Newton's 2nd Law
Definition
 the greater the mass of the mass of the object being accelerated, the greater the amount of force is need to accelerate the object
