1 00:00:00,000 --> 00:00:14,760 How would a test engineer use computation? 2 00:00:14,760 --> 00:00:20,120 Force is the capacity to do work or cause a physical change. 3 00:00:20,120 --> 00:00:22,920 Now that was the force of gravity at work. 4 00:00:22,920 --> 00:00:25,520 The work that we're doing here deals with propulsion. 5 00:00:25,520 --> 00:00:29,600 We're developing ways to overcome the force of Earth's gravity. 6 00:00:29,600 --> 00:00:32,240 Energy is the power available for us to use. 7 00:00:32,240 --> 00:00:35,040 We get our energy by fueling our bodies with healthy foods. 8 00:00:35,040 --> 00:00:40,120 When we ride a bike, our human body is the machine that propels it. 9 00:00:40,120 --> 00:00:43,200 Rockets carry their own propellants as an energy source. 10 00:00:43,200 --> 00:00:46,760 The propellants are burned in the engine, which provides the force needed to reach Earth 11 00:00:46,760 --> 00:00:47,760 orbit. 12 00:00:47,760 --> 00:00:51,560 Last but not least is calculating, or computation. 13 00:00:51,560 --> 00:00:55,960 Simply put, that's working with numbers to make them work for us. 14 00:00:55,960 --> 00:01:00,280 We use computation before, during, and after these rocket tests. 15 00:01:00,280 --> 00:01:04,400 All of these concepts can be and are put to use in our everyday lives to solve all sorts 16 00:01:04,400 --> 00:01:04,920 of problems.
