First Law of Motion |
If the net force acting on an object is zero, the object remains at rest or if in motion, continues moving in a straight line with constant speed. |
|
|
Inertia |
the tendency of an object to resist a change in its motion |
|
|
Second law of Motion |
the acceleration of an object is directly proportional to the net force on the object and indirectly proportional to its mass. |
|
|
gravity |
the attractive force between any two objects |
|
|
The force of gravity depends on two things: |
distance and mass |
|
|
Weight |
the gravitational force exerted on an object. measured in newtons. |
|
|
Centripetal acceleration |
Acceleration toward the center of a circular or curved path. |
|
|
Centripetal force |
the net force exerted toward the center of a curved path |
|
|
Projectile |
any object thrown into the air with only gravity acting on it. |
|
|
Third Law of Motion |
"to every action force their is an equal and opposite reaction force". |
|
|
Momentum |
p=mv |
|
|
Law of Conservation of Momentum |
If a group of objects exerts forces only on each other, their total momentum doesn't change. |
