Energy

The video tutorial explains that energy exists in various forms such as electrical, thermal, kinetic, and potential. It emphasizes that energy can be converted from one form to another but cannot be created or destroyed, highlighting the principle of energy conservation. Additionally, it defines the joule as the International Standard Unit of Energy, which is the work done by a force of one Newton moving through one meter.

Which of the following is NOT a form of energy mentioned in the video?

• Thermal

• Kinetic

• Magnetic

• Electrical

What is the principle that states energy cannot be created or destroyed?

• Law of Conservation of Energy

• Law of Motion

• Law of Gravity

• Law of Thermodynamics

Energy can be transformed from one form to another. Which of the following is an example of this transformation?

• A stone lying on the ground

• A battery powering a flashlight

• A book resting on a table

• A car parked in a garage

What is the International Standard Unit of Energy?

• Watt

• Newton

• Joule

• Calorie

How is one joule defined in terms of work done?

• The work done by a force of 2 Newtons moving through 2 meters

• The work done by a force of 1 Newton moving through 2 meters

• The work done by a force of 2 Newtons moving through 1 meter

• The work done by a force of 1 Newton moving through 1 meter
