FAQs on 3 Days Timetable Work, Energy and Power (2026) - Physics for JEE Main & Advanced

1. What is the work-energy theorem and how does it relate to potential and kinetic energy?
Ans. The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. This means that if work is done on an object, it will either gain kinetic energy (if the work is positive) or lose kinetic energy (if the work is negative). The theorem also relates to potential energy, as the work done against gravitational forces can change an object's potential energy, which in turn affects its kinetic energy when the object is in motion.
2. How do you calculate potential energy and what factors influence it?
Ans. Potential energy (PE) can be calculated using the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height above a reference point. The factors influencing potential energy include the object's mass, the height from which it is measured, and the local gravitational field strength.
3. What is kinetic energy and how is it calculated?
Ans. Kinetic energy (KE) is the energy an object possesses due to its motion. It is calculated using the formula KE = 0.5mv², where m is the mass of the object and v is its velocity. This means that the kinetic energy increases with the square of the velocity, indicating that even small increases in speed result in significant increases in kinetic energy.
4. What is the difference between work and power in physics?
Ans. Work is defined as the transfer of energy that occurs when a force is applied to an object over a distance, and it is calculated as the product of the force and the distance over which it is applied (W = Fd). Power, on the other hand, is the rate at which work is done, calculated as Power = Work/time. In essence, power indicates how fast work is being performed.
5. How can energy conservation be applied in solving problems related to work and energy?
Ans. The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another. In solving problems related to work and energy, this principle allows you to equate the total potential and kinetic energy at different points in a system. For example, in a closed system, the total mechanical energy (potential + kinetic) remains constant, enabling you to solve for unknown variables when certain values are provided.
