1 00:00:01,649 --> 00:00:07,929 Hello, fifth graders. It is Elizabeth here, and I want to talk to you about mechanical energy. 2 00:00:08,490 --> 00:00:16,670 What is that? Well, mechanical energy has kinetic energy and potential energy. 3 00:00:17,010 --> 00:00:25,670 But really, what is mechanical energy? So mechanical energy is the energy that produces 4 00:00:25,670 --> 00:00:36,969 is movement. All right, how many types are there? There's two types, kinetic and potential. 5 00:00:37,990 --> 00:00:47,450 So all you have to remember is movement, two types, kinetic and potential. Now, what are those? 6 00:00:48,149 --> 00:00:54,950 So now we're going to talk about what they are. Kinetic energy is energy in the form of movement. 7 00:00:55,670 --> 00:00:58,409 We all know what movement is, right? 8 00:00:58,409 --> 00:01:00,710 This is kinetic energy. 9 00:01:01,869 --> 00:01:06,349 But if I was standing in a tree, 10 00:01:06,349 --> 00:01:08,849 I would have potential energy. 11 00:01:08,849 --> 00:01:12,829 And now I will explain to you why. 12 00:01:12,829 --> 00:01:15,450 Kinetic energy, a good example of this 13 00:01:15,450 --> 00:01:17,549 would be riding your bicycle. 14 00:01:18,849 --> 00:01:23,400 Or when you throw a baseball. 15 00:01:23,400 --> 00:01:27,019 So that, why the ball is moving, 16 00:01:27,019 --> 00:01:30,420 that's kinetic energy, making it move. 17 00:01:31,299 --> 00:01:35,219 And then another example in nature would be moving water.
