---|---|---|---|---|---|
The total momentum of any group of objects remain the same unless outside forces also act on the objects. | Law Of Consevation of momentum
🗑
|
||||
Force | a push or pull that gives energy to an object.
🗑
|
||||
forces are measured in Newtons ; N | Units Of Forces
🗑
|
||||
Net Forces | total of all the forces acting on an object.
🗑
|
||||
The tendency of matter to resist a change in its motion. | Inertia
🗑
|
||||
Balanced forces | The net force acting on an object is zero
🗑
|
||||
Unbalanced Forces | the net force acting on an object is not zero.
🗑
|
||||
magnitude | the amount (size) of a measurements.
🗑
|
||||
Friction | a forcethat one surface exerts on another when the two surfaces are in contact with each other.
🗑
|
||||
Static friction | friction between un moving objects
🗑
|
||||
Kinetic friction | friction between moving objects
🗑
|
||||
Sliding friction | friction between objects that slide ( rub ) against each other.
🗑
|
||||
Rolling friction | occurs when an object rolls over a surface
🗑
|
||||
Fluid friction | occurs when an object moves through a fluid or a gas.
🗑
|
||||
New First Law Of Motion | Objects at rest will stay at rest and objects in motion will stay in motion at a constant velocity unless acted on by an unbalnced force.
🗑
|
||||
Newtons Second Law Of Motion | The net force acting on an object is equal to the product of the objects mass and acceleration.
🗑
|
||||
Newtons Third Law Of Motion | For every action force there is a reaction force that is equal but acts in the opposite direction.
🗑
|
||||
Law Of Universal Gravitation | all objects in the univers are attracted to each other; strengh of attraction demends on the objects masses and distance from each other.
🗑
|
||||
Freefall | The motion of an object when gravity is the only force acting on it.
🗑
|
||||
Terminal Velocity | Greatest velocity of a falling object; occurs when the force of gravity is equal to the force of friction
🗑
|
||||
Weight | A measure of the force of gravity on an object.
🗑
|
||||
Mass | The amount of matter in something.
🗑
|
||||
Centripetal Force | The force thats pulling on an object in circular motion towards the center of the circle.
🗑
|
||||
Geosynchronous Orbit | Occurs when the object orbits another object at a rate equal to teh 2nd objects rate of rotation.
🗑
