| 1J10.00 | Finding Center of Gravity | | |
| 1J10.09 | center of gravity | TPT 22(8),535 | Many examples of simple center of mass demonstrations. |
| 1J10.10 | map of state | PIRA 200 | Suspend a map of the state from holes drilled at large cities to find the "center of the state". |
| 1J10.10 | map of state | 1J10.10 | Sandwich of a map of the state between two plexiglass sheets and suspend from holes drilled at large cities to find the "center of the state". |
| 1J10.10 | map of Minnesota | Mp-7 | A plexiglass map of the state is suspended from several points. |
| 1J10.11 | find the center of gravity | AJP 36(1),x | Use a chalk line on the plumb bob and snap it to make a quick vertical line. |
| 1J10.12 | hanging shapes | M-32 | Use the plumb bob method to find the center of gravity of various geometric shapes. |
| 1J10.12 | hanging board | M-31 | Suspend an irregular board from several points and use a plumb bob to find the center of gravity. |
| 1J10.12 | irregular object center of mass | Disc 03-20 | Suspend an irregular object from several points and find the center of mass with a plumb bob. |
| 1J10.15 | hanging potato | Mp-13 | Hang a potato from several positions and stick a pin in at the bottom in each case. All pins point to the center of gravity. |
| 1J10.20 | loaded beam - moving scales | PIRA 1000 | |
| 1J10.20 | meter stick on fingers | 1J10.20 | Slide your fingers together under a meter stick and they meet at the center of gravity. Add a baseball hat to one end and repeat. |
| 1J10.20 | friction and pressure | M-50 | Slide your fingers under the meter stick to find the center of mass. |
| 1J10.20 | meter stick on fingers | Disc 04-15 | Slide your fingers under a meter stick to find the center of mass. |
| 1J10.25 | center of gravity of a broom | PIRA 500 | |
| 1J10.25 | center of gravity of a broom | 1J10.25 | Bring your fingers together under a broom the find the center of gravity. |
| 1J10.25 | center of gravity of a broom | Mp-15 | Find the center of gravity of a broom, hang a kg mass somewhere on the broom, find the new center of gravity, calculate the weight of the broom by equating torques. |
| 1J10.26 | balance beam and bat | PIRA 1000 | |
| 1J10.26 | balance beam and bat | 1J10.26 | |
| 1J10.30 | meter stick on fingers | PIRA 500 | |
| 1J10.30 | loaded beam - moving scales | 1J10.30 | Slide the scales together under a loaded beam noting the scale readings of the moving and stationary scales. |
| 1J10.30 | loaded beam - moving scales | TPT 10(8),469 | Instead of moving the masses on the beam, move the scales under the beam. Same as bringing your fingers together under the meter stick. |
| 1J10.41 | your center of gravity | TPT 17(4),254 | Two methods for measuring the center of gravity of a person are shown. |
