|---|---|---|---|---|---|
| show | Conservation of energy
🗑
|
||||
| The work output of any machine cannot exceed the work input. In an ideal machine, where no energy is transformed into heat, work input = work output and (Fd)input=(Fd)output | show 🗑
|
||||
| In the absence of an external force, the momentum of a system remains unchanged. Hense, the momentum before an event involving only internal forces is equal to the momentum after the event: mv(before envent)=mv(after envent) | show 🗑
|
||||
| The percentage of the work put into a machine that is converted into useful work output. (It is useful energy output divided by total energy input) | show 🗑
|
||||
| A collision in which colliding objects rebound without lasting deformation or the gereration of heat. | show 🗑
|
||||
| The property of a system that enables it to do work | show 🗑
|
||||
| show | Impulse
🗑
|
||||
| A collision in which the colliding objects become distorted, gererate heat, and possibly stick together. | show 🗑
|
||||
| show | Joule
🗑
|
||||
| show | Kinetic Energy
🗑
|
||||
| The product of the mass of an object and its velocity | show 🗑
|
||||
| The stored energy that a body possesses because of its position | show 🗑
|
||||
| show | Power
🗑
|
||||
| show | Relationship of impulse and momentum
🗑
|
||||
| show | Work
🗑
|
||||
| The work done on an object equals the change in kinetic energy of the object: Work=(triangle)KE | show 🗑
|
||||
| show | Centripetal force
🗑
|
||||
| The attractive force between objects due to mass | show 🗑
|
||||
| show | Inverse-square law
🗑
|
||||
| show | Law of universal gravitation
🗑
|
||||
| The curved path followed by a projectile near the Earth under the influence of gravity only. | show 🗑
|
||||
| show | Projectile
🗑
|
||||
| show | Tangential velocity
🗑
|
||||
| The proportionality constant in Newton's law of gravitation | show 🗑
|
||||
| show | Weightlessness
🗑

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.
