Newton's First Law
|
Inertia; an object will keep moving or stay at rest unless a net force acts on it
|
|
Newton's Second Law
|
more force causes more acceleration; more mass causes less acceleration; F=ma
|
|
Newton's Third Law
|
For every action there is an equal and opposite reaction
|
|
force
|
anything that causes a change or cause of motion; measured in Newtons; are vectors; any push or pull
|
|
net force
|
the net force is the result of all of the forces acting on an object; sum of all forces and has direction
|
|
inertia
|
the property of an object that resists change of motion; more mass=more inertia
|
|
weight
|
force of gravity pulling on mass; w=mg
|
|
At equilibrium the following are true
|
Fnet = 0N (no net force)
a = 0m/s2 (no acceleration) Change in velocity = 0m/s2 (constant speed) ex. object at rest |
|
free body diagram
|
a picture that represents an object and all of the forces that are acting on it
|
|
system
|
a part of the universe that has been chosen for study
|
|
environment
|
everything that surrounds a system
|
|
non-contact force
|
a force that can be exerted over a distance and does not require contact in order to be exerted
|
|
contact force
|
a force exerted when an object is in contact with another object (frictional force, air resistance, tension force, applied force, spring force)
|
|
Force of Friction
|
the force that goes against your force
|
|
Tension Force
|
anything that exerts energy in a long form
|
|
Normal Force
|
the force that pushes upward
|
|
Kinetic Friction
|
the force opposing friction so it moves
|
|
Spring Force
|
the force exerted by a compressed or stretched spring on any object attached to it
|
|
Applied Force
|
force that is applied to an object by a person or another object
|
|
Static Friction
|
the counteractive force that opposes the applied force and keeps the object at rest
