Work and Kinetic Energy
![Work](https://cloudfront.jove.com/files/media/science-education/science-education-thumbs/12663.jpg)
Work is done when energy is transferred from one object to another. In other words, work is when a force acts on something that undergoes a…

Work is done on an object when energy is transferred to the object. In other words, work is done when a force acts on a body that undergoes a…
![Types of Potential Energy](https://cloudfront.jove.com/files/media/science-education/science-education-thumbs/13504.jpg)
Potential energy is also known as energy at rest or stored energy. Common types of potential energy include the gravitational potential energy stored…

The amount of kinetic energy of an object depends on its mass and speed. Consider two balls of different masses rolling down an inclined plane at the…
![Kinetic Energy - II](https://cloudfront.jove.com/files/media/science-education/science-education-thumbs/12667.jpg)
The kinetic energy of a particle is one-half of the product of the particle’s mass and the square of its speed. Note that just as…
![Work-energy Theorem](https://cloudfront.jove.com/files/media/science-education/science-education-thumbs/12668.jpg)
According to Newton’s second law of motion, the sum of all the forces acting on a particle (net force) determines the rate of change in the…
![Work-Energy Theorem for Motion Along a Curve](https://cloudfront.jove.com/files/media/science-education/science-education-thumbs/14700.jpg)
The work-energy theorem can be generalized to the motion of a particle along any curved path. The simple argument here is that the curved path can be…

The center-of-mass framework helps to easily describe the work done on rigid bodies. Since the internal forces in a rigid body do no work, they can…
![Work Done by Gravity](https://cloudfront.jove.com/files/media/science-education/science-education-thumbs/14750.jpg)
Gravitation is one of the four fundamental forces in nature. The force between objects on Earth and Earth itself is called gravity.
Like other…
