This lesson covers words associated with various sports. Students will learn the names of sports, their meanings, and how to use these words in speech and writing. Examples include handball, netball, cricket, hockey, football, and athletics.
- 01:44 “say "an" it is "e". So what is a handball? This is a team sport where two teams of seven players each. Six players and a gookipa pass and bounce a ball, trying to throw it to the goose of the opposing team. Next is the n...”
- 02:36 “on three storms, equally consider a picture on the screen. Next is hockey. This is a bath and ball game played between two teams of eleven players on a feed or pitch with a wicket at each end comprising two balls, balanc...”
- 00:54 “which is sport. Sport. This talks about any engaging activity that uses physical force or skews competitively while considering a set of routes that has been laid down. Here, we are going to discuss names of major nation...”
Work, Energy and Power
This lesson covers the definitions of work, energy, and power. It includes calculations for work done, gravitational potential energy, and power in watts. The lesson also distinguishes between kinetic and potential energy and explains energy transformation and the law of conservation of energy.
- 08:56 “6 m above the ground, calculate the work done and lift the ball. Bearing in mind that our solution due to gravity is 10 m per second squared. Now, the work done, the formula is mg h. Our mass is 10. 10 multiplied by a so...”
- 18:44 “and our H equals 40 meter above the ground. Now, substituting the values, we have 1.5 multiplied by 10 multiplied by 40. So, we have 600 joules as the potential energy of the mango before it starts dropping. The other pa...”
- 00:47 “as it relates to mechanical energy, then solve simple problems or needs. Work, work is done on an object when you transfer energy to that object. If one object transfer or gives energy to another, the first object does w...”
Energy Transformation and Power
The lesson covers the process of energy transformation from one form to another, including potential and kinetic energy. It explains the laws of conservation of energy and provides examples of energy conversion, such as mechanical and solar energy. The lesson also defines power and presents its form
- 11:47 “is drawn from a height of 100 meter above the ground. Calculate one potential energy before dropping it. Two, what is the potential energy and kinetic energy of the ball, 8 meter to the ground. And lastly, what is the sp...”
- 04:42 “before the object strikes the ground, and the kinetic energy wishes zero, and the maximum height has now increased, and has been transformed to maximum kinetic energy, before the object strikes the ground. Example, a bal...”
- 14:17 “Therefore, our kinetic energy is equal to 3600 minus 1,440. So, we are left with 2,460 joules. And lastly, to calculate the speed with which the object strikes the ground, we relate the formula for kinetic energy to that...”
