Colin measured the speed of an alpha particle that was emitted from a U-238 nucleus to be 2.20x10^8 m/sec. Calculate the kinetic energy. As sam_021 said, you have neglected relativistic effects. Stationary objects have no kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another). If we can find the potential energy, we can find the kinetic energy. velocity (v) = 0 = 0. meter/second . v car with an arrow- the car's velocity vector; m car - car's mass; KE car - car's kinetic energy; v car - car's speed; kg- kilograms; J- Joules; m/s- meters per second; Notes. So the kinetic energy E k is given by combining the last two equations : However, the velocity is changing from v to 0 over the distance S, so the average value of velocity must be taken to calculate the overall energy. Square the velocity value and multiply it with mass of the object. You have nearly answered your own question. Mass units in metric and imperial units. The coefficient of restitution is used to find the extent to which the collision is inelastic or elastic and its value lies between zero and one.
