Energy and Work related - Did i do this right?

• mks
In summary, potential energy is energy stored in an object, while gravitational potential energy is achieved by working against the force of gravity. Work is the transfer of mechanical energy, and kinetic energy is the energy of motion. Mechanical energy is a combination of both potential and kinetic energy. The Work-Kinetic energy theorem describes the relationship between doing work on an object and the resulting kinetic energy. Negative work removes energy from an object, while positive work adds energy to an object. Conservative forces do work on an object and the amount of work done is independent of the path taken, while non-conservative forces do work on an object and the amount of work done is dependent on the path taken.

3. Work- the transfer of mechanical energy.
4. Kinetic energy- the energy of motion.
5. Mechanical energy- combination of kinetic and potential energy.
6. Work-Kinetic energy theorem- the special relationship between doing work on an object and the resulting kinetic energy of the object.
7. Negative work- removes energy from an object.
8. Positive work- adds energy to an object.
9. Conservative force- when a force does work on an object and the amount of work done is independent of the path taken.
10. Non-conservative force- when a force does work on an object and the amount of work done is path-dependent.

1. What is the difference between energy and work?

Energy refers to the ability of an object to do work, while work is the transfer of energy from one object to another. In other words, energy is the potential to do work, while work is the actual movement or change caused by that energy.

2. How are energy and work related?

Energy and work are closely related because work is the transfer of energy from one object to another. When work is done, energy is either transferred to or from an object, causing a change in its state or motion.

3. What are the different forms of energy?

There are many forms of energy, but some common types include kinetic energy (energy of motion), potential energy (stored energy), thermal energy (energy of heat), chemical energy (energy stored in chemical bonds), and electromagnetic energy (energy of light and other electromagnetic waves).

4. How is energy conserved in a closed system?

The law of conservation of energy states that energy cannot be created or destroyed, only transferred from one form to another. In a closed system, where no energy is lost to the outside environment, the total amount of energy remains constant.

5. How can we calculate the amount of work done?

The amount of work done can be calculated by multiplying the force applied to an object by the distance it moves in the direction of the force. The equation for work is W = F x d, where W is work, F is force, and d is distance.
