• 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

• this force pulls any 2 objects toward one another
• example would be: stopping a swing from swinging

• an object has this because the force of gravity pulls down on the object
• a spring scale is used to measure this...

• 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

• a force that causes something to to move
• it pulls objects down or
• pulls 2 objects towards one another

• this force pull or push forces that exists around charged particles
• like charges will repel - positive/positive
• unlike charges will attract - positive/negative

• 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

their primary job is to make work easier

examples include: inclined plane, wedge, pulley, wheel and axle, lever, screw

• slows the motion of moving objects
• produces heat energy like rubbing your hand together

energy of motion or moving

examples:

• pushing a toy car down a ramp
• a child going down a slide

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

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
