ANSWER THE FOLLOWING QUESTIONS:-
a) Identify the types of motion:
i. Motion of an electric fan.
ii. Revolution of earth around the sun .
b) What do you mean by 1 joule ?
c) What is volume? Write the standard unit of volume.
d) Distinguish between kinetic energy and potential energy.
Answers
Answer:
a.i. Motion of fan is Rotational or Circular.
ii. Rotatory motion
b. Joule = kgm²/s²
c. Volume is the quantity of three-dimensional space enclosed by a closed surface and unit is m³
Kinetic Energy
Potential Energy is the order of statements
1. Kinetic energy is the kind of energy present in a body due to the property of its motion
Potential Energy is the type of energy present in a body due to the property of its state
2. It can be easily transferred from one body to another
It is not transferrable
3. The determining factors for kinetic energy are Speed or velocity and mass
Here, the determining factors are Height/ distance and mass
4. Flowing water is one of the examples for kinetic energy
Water present at the top of hill is an example of potential energy
5. It is relative with respect to nature
It is non-relative with respect to nature
