00:01 This problem is dealing with the difference between potential and kinetic energy.

00:05 So we're going to go through different examples, and i will number them and we'll see which ones are which.

00:10 So the first example is going to be a bicyclist that is peddling.

00:15 And so this bicyclist is peddling, and that means it's moving.

00:19 And so it has to have kinetic energy to move.

00:22 However, it's also gaining potential energy.

00:25 So if you have the option to put both, i would put both.

00:28 And that's because it is going up a heel.

00:31 So the cycling part means it has kinetic energy.

00:35 Definitely has kinetic energy.

00:36 So if there's only one option, put that one.

00:39 If you're able to put two, put potential also.

00:42 That's simply because if they're going up a hill, they are gaining potential gravitational potential energy.

00:50 The other situations i'm going to give you, do not have more than one answer.

00:53 And so the second one would be when an archer draws back their bow.

00:57 And so when they pull that string and hold it in place, they have now given the bow a type of potential energy.

01:04 And that is elastic potential energy.

01:06 And it has potential for that energy to turn an arrow into movement, which is kinetic energy.

01:13 The third example would be volleyball.

01:15 So if a volleyball player spikes a ball, they are hitting this ball and giving it motion.

01:20 And so remember, energy in motion is kinetic energy.

01:26 Same thing with the baseball.

01:27 So if you were to throw a baseball to a base, that ball is now moving through the air, and that is a kinetic energy.

01:35 So remember, kinetic is the energy associated with motion.

01:38 Potential energy is stored energy.

01:41 And so the next would be food.

01:43 And so there is chemical bonds stored in food.

01:46 And these are called chemical potential energy.

01:49 Same thing with batteries.

01:51 It has the potential to give energy to a human.

01:54 That's why we eat our food.

01:56 Number six, wind blowing through your hair.

01:58 Well, when the wind blows through your hair, your hair is going to move.

02:03 That movement is kinetic energy.

02:06 Same thing when you're walking.

02:08 If you're going for a walk down a street, you are moving.

02:11 You are not elevating yourself to give you potential energy.

02:15 You have kinetic energy...
