time Each pit has a mass of one kilogram and
- 00:21
she dropped them in from a height A zero point
- 00:24
five meters what's the potential energy of the pit At
- 00:28
the instant it falls from her hand And here the
- 00:32
potential answers way go day huh Well these are some
- 00:37
really big peach pit But that's how we get politic
- 00:40
peaches All right At the instant the peach pit is
- 00:43
released from margaret's hands It's not moving it will But
- 00:47
we're talking the very very incident it's released So all
- 00:51
of the energy involved is potential energy not kinetic All
- 00:59
right potential energy equals mass times gravity times height So
- 01:04
all we have to do is plug in the Numbers
- 01:06
1 kilogram times 10 meters per second squared times point
- 01:11
five meters gives us an answer of five jewels So
- 01:14
option is the correct answer To be sure to memorize
- 01:17
These equations They'll come in handy a test time Another
- 01:20
thing to remember Be nice to margaret Maybe she'll take
