Net force
|
also known as a resultant force, is a vector produced when two or more forces { F1, F2, … } act upon a single object
|
|
Mass
|
amount of matter an object contains
|
|
Weight
|
mass x force of gravity, units are in N
|
|
inertia
|
resistance of an object to change it's motion
|
|
weightlessness
|
when no gravitational force is exerted on an object
|
|
gravity
|
the attractive force that exists between all objects
9.8 m/s2 |
|
equilibrium
|
when the net force on an object is zero
|
|
free body diagram
|
a diagram that shows the direction of the force(s) acting on an object
|
|
friction
|
the force resisting movement when two objects touch
|
|
static friction
|
the force when two objects are touching but not moving, frictional resistance a stationary object must overcome in order to be set in motion
|
|
kinetic (sliding) friction
|
the force when two objects are touching and moving
|
|
coefficient of friction
|
symbol "mu" used to represent the frictional force
