Kinetic energy is energy due to motion and potential ene. For example if a an object with a mass of 10 kg m 10 kg is moving at a velocity of 5 meters per second v 5 ms the kinetic energy is equal to 125 Joules or 12 10 kg 5 ms 2. The work done by thenet force on an object equals the change in kinetic energy of the object. This physics video tutorial provides a basic introduction into kinetic energy and potential energy. Relavitve Motion 57 5. KE 588 kJ. KE ½ m v 2. Double the speed and the KE increases by four times. Appropriate for secondary school students and higher. SAT Subject Physics Formula Reference Work Energy Power continued W KE W workdone KE kinetic energy The work-energy theorem.

Kinetic Energy Solved Examples Underneath are questions on Kinetic energy which aids one to understand where they can use these questions. In classical mechanics kinetic energy KE is equal to half of an objects mass 12m multiplied by the velocity squared. Not a truly complete list of formulas though as some things are missingI cant think of any more formulas for this cheat sheet though so suggestions on what to add would be helpful. Mostly algebra based some trig some calculus some fancy calculus. In classical mechanics the kinetic energy of a point object an object so small that its mass can be assumed to exist at one point or a non-rotating rigid body depends on the mass of the body as well as its speed. K E m v 2 2 K E 0213 6261 2 2 K E 0213 392 2. KE ½ m v2. Work Power Energy 10 11 8. T elapsed time. EKEPE Etotalenergy KE kinetic energy PE potential energy The definition of total me-chanical.

SAT Subject Physics Formula Reference Work Energy Power continued W KE W workdone KE kinetic energy The work-energy theorem. Highway speed is way more dangerous. Not a truly complete list of formulas though as some things are missingI cant think of any more formulas for this cheat sheet though so suggestions on what to add would be helpful. KE ½ mv2. A 1 kg meteorite strikes the Moon at 11 kms. The work done by thenet force on an object equals the change in kinetic energy of the object. To crack these kinds of challenges one needs to have a proper understanding of physics formula as well as its concepts. M is the mass in kilograms kg.
