FAQs on Work/energy problem with friction Video Lecture - Crash Course for PAT

1. What is work and energy?

Ans. Work is defined as the transfer of energy that occurs when a force is applied to an object and the object is displaced in the direction of the force. Energy, on the other hand, is the capacity to do work. It can exist in different forms such as kinetic energy, potential energy, and thermal energy.

2. How are work and energy related?

Ans. Work and energy are closely related concepts. When work is done on an object, energy is transferred to that object, resulting in a change in its energy. This change in energy can be in the form of an increase or decrease in kinetic energy or potential energy, depending on the circumstances.

3. What is the difference between kinetic energy and potential energy?

Ans. Kinetic energy is the energy possessed by an object due to its motion, while potential energy is the energy possessed by an object due to its position or state. Kinetic energy depends on the mass and velocity of the object, while potential energy depends on factors such as height, elasticity, and chemical composition.

4. Can energy be created or destroyed?

Ans. According to the law of conservation of energy, energy cannot be created or destroyed. It can only be transferred or transformed from one form to another. This means that the total amount of energy in a closed system remains constant.

5. How is work calculated?

Ans. The work done on an object is calculated by multiplying the magnitude of the force applied to the object by the distance over which the force is applied. Mathematically, work (W) is equal to the force (F) multiplied by the displacement (d) and the cosine of the angle (θ) between the force and displacement vectors. Therefore, W = Fd cos(θ).
