---|---|---|---|---|---|
MOMENTUM | THE PRODUCT OF AN OBJECT'S MASS AND ITS VELOCITY
🗑
|
||||
FORMULA FOR MOMENTUM | m = pv
🗑
|
||||
lAW OF CONSERVATION OF MOMENTUM | The total momentum of any group of objects remains the same unless outside forces also act on the object
🗑
|
||||
FORCE | a push or pull that gives energy to an object
🗑
|
||||
UNITS OF FORCE | Forces aare measured in Newtons; N
🗑
|
||||
NET FORCE | The total of all the forces acting on an object
🗑
|
||||
INERTIA | The tendency of matter to resist a change in motion.
🗑
|
||||
BALANCED FORCES | the net force acting on an object is zero
🗑
|
||||
UNBALANCE FORCES | The net force acting on an object is NOT zero
🗑
|
||||
MAGNITUDE | the amount (size) of a measurement
🗑
|
||||
FRICTION | a force that one surface exerts on another when the two surfaces are in contact with eachother
🗑
|
||||
STATIC FRICTION | Friction between non-moving objects
🗑
|
||||
KINETIC FRICTION | Friction between moving objects
🗑
|
||||
SLIDING FRICTION | Friction between objects that slide (rub) against eachother
🗑
|
||||
ROLLING FRICTION | occurs when an object rolls over a surface
🗑
|
||||
FLUID FRICTION | occurs when an object moves through a fluid or a gas
🗑
|
||||
NEWTONS FIRST LAW OF MOTION | Objects at rest will stay at reast & objects in motion will stay in motion at a constant velocity unless acted on by an unbalanced force
🗑
|
||||
NEWTONS SECOND LAW OF MOTION | The net force acting on an object is equal to the product of the objects mass & 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 universe are attracted to eachother the size of the attraction depends on the mass of the objects and the distance between them.
🗑
|
||||
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 that is pulling 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 the 2nd objects rate of rotation
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
