Match Energy Concepts: Work, Joule, Potential & Kinetic Energy

In summary, work is the transfer of mechanical energy and is achieved by doing work against the force of gravity. Kinetic energy is the energy of motion and potential energy is achieved by doing work against the force of gravity. The work-kinetic energy theorem is a special relationship between doing work on an object and the resulting kinetic energy of the object. Mechanical energy is the combination of kinetic and potential energy. A conservative force adds energy to an object, while a non-conservative force removes energy from an object. Positive work refers to when a force does work on an object and the amount of work done is independent of the path taken, while negative work is when the amount of work done is path-dependent. The joule is the unit of measurement

mechanical energy-combination of kinetic and potential energy.

positive work-when a force does work on an object and the amount of work
done is independent of the path taken.

kinetic energy-the energy of motion.

negative work-when a force does work on an object and the amount of work
done is path-dependent.


potential energy-achieved by doing work against the force of gravity.
 
  • #3
gravitational potential energy-achieved by doing work against the force of gravity.

conservative force-adds energy to an object.

non-conservative force.-removes energy from an object.

work-kinetic energy theorem-the special relationship between doing work on an object
and the resulting kinetic energy of the object

-energy that is stored in by an object( But i don't know what this is T.T)... Can anyone help please/

You wrote: "potential energy-achieved by doing work against the force of gravity," and "gravitational potential energy-achieved by doing work against the force of gravity." your second answer is correct.

When energy is stored, is it doing something...or does it have the potential to do something?
 
  • #6
potential energy-
energy that is stored in by an object

right?!

So is everything right ?...

Your answers for conservative force, non-conservative force, positive work, and negative work are incorrect. If you don't have a text with these definitions, I would suggest using wikipedia or some other internet source to find their definitions. People are more likely to remember information if they research it.

1. What is work in terms of energy?

Work is defined as the application of force over a certain distance. In terms of energy, work is the transfer of energy from one object to another. This can result in a change in the object's velocity, position, or temperature.

2. What unit is used to measure work?

The unit used to measure work is the Joule (J). One Joule is equal to the work done when a force of one Newton is applied over a distance of one meter.

3. What is potential energy?

Potential energy is the energy an object possesses due to its position or state. It is often described as "stored" energy because it has the potential to be converted into other forms of energy, such as kinetic energy.

4. How is kinetic energy defined?

Kinetic energy is defined as the energy an object possesses due to its motion. It is dependent on the mass and velocity of the object, and can be calculated using the equation KE = 1/2 * m * v^2, where m is mass and v is velocity.

5. Can potential and kinetic energy be converted into each other?

Yes, potential and kinetic energy can be converted into each other. This is known as the Law of Conservation of Energy, which states that energy cannot be created or destroyed, only transferred or converted into different forms.
