Aug 05, 2013 · You should understand the work-energy theorem so you can: Calculate the change in kinetic energy or speed that results from performing a specified amount of work on a body. The Physics Kahuna worked hard to drill this into your brains. The basic idea is that the change in kinetic energy of a system is equal to the work done on the thing.

Use the work-kinetic energy theorem to determine how far the car must travel for its speed to reach 2.0 m/s. A 75 kg bobsled is pushed along a horizontal surface by two athletes. After the bobsled is pushed a distance of 4.5 m starting from rest, its speed is 6.0 m/s. Find the net force on the bobsled.

The kinetic energy of a 10-kg mass traveling at 1 m/s is. The unit of energy is the joule, as mentioned previously. Work-Kinetic Energy Theorem. The work done on an object is equal to the change in kinetic energy of the object. This is known as the work-kinetic energy theorem. It is derived as follows. The W-KE theorem is very useful.

The change in energy is work. “Kinetic” identifies the unique condition – motion. We now re-invent and rename the work done by the net force; and introduce the fundamental version of the Work Energy Theorem. where. This outcome is the fundamental step in the development of other refined versions of the work energy theorem.
