 # HC Verma Solutions Vol 1 Chapter 8 Work and Energy

HC Verma Solutions Vol 1 Chapter 8 Work and Energy gives students the opportunity to learn the right method of solving questions related to important topics like kinetic energy, potential energy, work done by the force of gravity,  finding power, etc. This chapter contains questions which are frequently asked in in prominent examinations such as JEE Advanced and students can develop better skills and prepare completely by referring to the solutions. You will get to learn topics of work and energy in the problems given here such as:

• We will be dealing with questions related to work done against resistance and work done against friction.
• Solve questions on the law of conservation of energy and the energy required to overcome friction.
• Understand problems related to work done when force is parallel to the inclined plane and tackle problems by applying the work-energy principle.

Students will further learn about topics like;

1. Kinetic Energy
2. Work and Work-energy Theorem
3. Calculation of Work Done
4. Work-energy Theorem for a System of Particles
5. Potential Energy
6. Conservative and Nonconservative Forces
7. Definition of Potential Energy and
8. Conservation of Mechanical Energy
9. Change in the Potential Energy in a Rigid-body-motion
10. Gravitational Potential Energy
11. Potential Energy of a Compressed or Exercises
12. Extended Spring
13. Different Forms of Energy: Mass Energy
14. Equivalence

## Important Questions In Chapter 8

1. When a ball falls from a great height there are some changes to its gravitational potential energy. What happens to the energy when it reaches the ground? Also, explain what will happen to the energy after it strikes the ground?

2. Do you think that the work done by kinetic friction on an object have a result as Zero or positive?

3. You lift a heavy box from the ground and keep it on the storage shelf. Therefore, the work done by you on the box does not depend on

(a) the weight of the box (b) the time taken in completing the action (c) the path taken by the box (d) your own weight.

4. An object having certain mass moves down on a smooth vertical circular track. During the movement, the object is in

(a) radial equilibrium (b) horizontal equilibrium (c) vertical equilibrium (d) none of these.

5. A charged particle has a magnetic force that is always perpendicular to its velocity. Keeping this in mind can the magnetic force change the velocity and speed of the particle?
