The kinetic energy would be KE= ½mv 2,where m is the mass of the pendulum, and v is the speed of the pendulum. At its highest point (Point A) the pendulum is momentarily motionless. All of the energy in the pendulum is gravitational potential energy and there is no kinetic energy.... The kinetic energy of an object is the energy that the object possesses because it is in motion. In order for something to have kinetic energy, you must "do work" on it--push or pull. This involves Newton's second law and motion equations. The calculation of kinetic energy is the way to express the fact of a moving object's ability to do work on anything it hits. The result of the calculation

In this system, any work done in rotating the shaft results in a transfer of kinetic energy to the water. If the drive force is removed from the shaft after some time, there will still be some residual motion. However, the motion will eventually die down and result in an increase in thermal energy of the water.... Potential Energy and Work The potential energy is equal to the amount of work done to get an object into its position. For example, if you were to lift a book off the floor and place it on a table.

Thus, "kinetic energy" is the energy of motion --it's ability to do work. The faster the body moves the more kinetic energy is produced. The greater the mass and speed of an object the more kinetic energy there will be. As the train accelerates down the hill the potential energy is converted into kinetic energy. There is very little potential energy at the bottom of the hill, but there is a how to stop your knees from caving in when squatting The kinetic energy of the bullet is the energy that is transferred to the target when hit. It is also the energy that the shooter absorbs through recoil by shooting. It is also the energy that the shooter absorbs through recoil by shooting.

The kinetic energy gained by the body is equal to Fs, and this must therefore be the work done in giving it a velocity v. However we know that F = ma and v 2 = u 2 + 2as where u and v are the initial and final velocities of the object. how to make horn work with quick release A battery-free flashlight, for example, harnesses enough kinetic energy to power an LED bulb for 45 minutes after 30 seconds of shaking, but not all kinds of shaking will work.

- The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Click on the image to see an animation of wind at work.
- Kinetic Energy All moving things have kinetic energy. It is energy possessed by an object due to its motion or movement. These include very large things, like planets, and very small ones, like atoms.
- A convenient energy unit, particularly for atomic and nuclear processes, is the energy given to an electron by accelerating it through 1 volt of electric potential difference. If an electron starts from rest at the negative plate, then the electric field will do work eV on it, giving it that amount of kinetic energy when it strikes the positive plate.
