| show | Slope of graph gives acceleration.
Hence:
a = 30ms-1/3s = 10 ms-2

| show | distance/speed
🗑

| show | distance/time
🗑

| show | The net force on her is zero Newtons at
her constant terminal velocity because
she has no net acceleration. Hence by
Newton’s second law, if anet = 0, then Fnet
= m anet = 0 N.

| Mary has a mass of 65 kg. Calculate the size of the force of gravity acting on her as she falls. | show 🗑
|

| show | -drag and weight balanced
-no accelerations; a=0
-at fastest possible speed
-constant speed
-zero change in speed, zero slope, zero acceleration
-F=m,a. if a=0 f=0; weight less
🗑

| show | ------- as constant acceleration
🗑
|
||||
| show | acceleration/changing speed; no slope no acceleration= constant speed
🗑
|
||||
| show | speed/velocity, more slope speed; no slope no acceleration = constant speed

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.
