gravity
|
the force that pulls objects towards each other
|

|
gravity
|
the force that pulls objects towards each other
|
|
|
free fall
|
when gravity is the only force on a falling object ex. sky diving before you open the parachute
|

|
|
|
force
|
a push or pull
|
|
|
air resistance
|
the upward force on an object; the opposite of motion
|
|
|
mass
|
the amount of matter (space) inside an object
|
|
|
universal gravitation
|
any 2 objects in the universe are attracted to each other through gravity
|
|
|
what 2 things are gravity dependant on?
|
the mass of the 2 objects (the smaller the object the weaker the force) distance from the objects (the further away the weaker the force)
|
|
|
inertia (Newton's first law of motion)
|
an object will stay in place unless something moves it; an object will continue in a straight line unless something stops it
|
|
|
give 2 examples of newtons first law of motion
|
#1 a boulder will stay at the top of a hill unless gravity pulls it down or something pushes it down the hill
#2 a soccer ball will continue in a straight line unless something blocks it |

|
|
|
projectile motion
|
an object that is thrown, is pulled by the same amount of gravity as the same object being dropped
|
|
|
force
|
a push or pull
|

air resistance
|
the upward force on and object; the opposite of motion

|
|
|
inertia (Newton's first law of motion)
|
an object will stay in place unless something moves it; an object will keep moving in a straight line unless something stops it
|
|
|
give 2 examples of newtons first law of motion
|
#1 a boulder wil stay at the top of a hill unless gravity pulls if or something pushes it down the hill #2 a soccer balls will continue in a straight line towards the goal unless it is blocked

weight
|
the amount of gravity pulling on an object formula for weight= mass x 9.8 m/s2
|
|
|
centripetal force
|
any force that causes an object to move in a circle
