|---|---|---|---|---|---|
| for constant acceleration, distance = | x = x0 + v0*t + 1/2*a*t^2
🗑
|
||||
| for constant acceleration, velocity = | v = v0 + a*t
🗑
|
||||
| for constant acceleration, velocity^2 = | v^2 = v0^2 + 2*a*x
🗑
|
||||
| average velocity = | vavg = 1/2*(v+v0)
🗑
|

| x vs. t graph | slope = instantaneous velocity
straight line = constant velocity
curved line = changing velocity (acceleration)
🗑
|
||||
| v vs. t graph | slope = instantaneous acceleration
straight line = constant acceleration
curved line = changing acceleration
area beneath the curve = total displacement
🗑
|

| projectile motion | body projected by external force and continuing in motion by its own inertia
🗑
|
||||
| peak height of projectile found by.. | v0*sin(theta) = sqrt(2*g*h)
🗑
|
||||
| what dictates time of flight for projectile? | vertical velocity only
🗑
|
||||
| air resistance | created when projectile collides with air molecules; increased with large surface area, smooth surfaces experience less, generally higher v means higher air resistance
🗑

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.
