|
Inertia
|
objects tendency to resist motion
|
|
|
|
Newton's 1st Law Of Motion
|
object @ rest remains @ rest
|
law of inertia
|
|
|
Force
|
action exerted on an object that will change the objects motion.
|
|
|
|
Net Force
|
single force whose effects on an object are equal to several forces acting on an object
|
|
|
|
Equilibrium
|
state where net force is zero.
|
|
|
|
Normal Force
|
force acting perpendicular to that surface.
|
|
|
|
Newton's 2nd Law of Motion
|
acceleration of an object is proportional to the net force and mass.
fn=ma |
|
|
|
Newton's 3rd Law of Motion
|
action reaction, forces happen at the same time.
|
|
|
|
Mass
|
property of an object which determines resistance
|
|
|
|
Weight
|
measure if gravitational force on an object
|
|
|
|
static friction
|
force needed to make an object move. more then kinetic
|
|
|
|
kinetic friction
|
force needed to keep an object in motion
|
|
|
|
free body diagram
|
shows forces as vectors and forces upon an object. doest show forces exerted by the object
|
|
|
|
What is inertia directly related too?
|
mass
|
|
|
|
2nd apples of equilibrium
|
object at rest
object in motion with constant velocity |
|
|
|
What's the relationship bet acceleration and mass?
|
mass goes up acceleration goes down
|
|
|
|
Force and acceleration when the force is increasing?
|
mass is constant
net force goes up acceleration goes up |
|
|
|
what happens to an object when the net force acts on it?
|
causes acceleration
|
