|---|---|---|---|---|---|
| Work | show 🗑
|
||||
| When F and d are perpendicular | show 🗑
|
||||
| show | rate at which work is done; Watts = J/s
🗑
|
||||
| show | E of motion; = 1/2 mv^2
🗑
|
||||
| show | E of position; = mgh
🗑
|
||||
| show | E is drained away in form of heat
🗑
|
||||
| show | KE + PE = total E
🗑
|
||||
| show | = change in KE
🗑
|
||||
| show | friction
🗑
|
||||
| Conservation of E | show 🗑
|
||||
| show | these allow F to be reduced but distance that the force is exerted over is increased to compensate
🗑
|
||||
| Efficiency (Pulley) | show 🗑
|
||||
| show | load distance multiplied by the number of pulleys present
🗑
|
||||
| Momentum | show 🗑
|
||||
| show | J = Ft = change in momentum
🗑
|
||||
| show | Total p initial = Total p final; (p of object a)(p of object b)i = (pa)(pb)f
🗑
|
||||
| Completely inelastic collisions | show 🗑
|
||||
| show | objects dnt stick together after collision; KE is conserved; use momentum AND KE equations here
🗑
|
||||
| Center of Mass Equation | show 🗑

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.
