How do you find the kinetic energy in joules
WebOct 24, 2024 · The Swiss's kinetic energy is 1/2 times .05 kilograms times two meters per second squared, which is .1 Joules, or half the kinetic energy of the cheddar. So we can see that at the same … WebThis is a common misconception, remember that the angle theta in W = FDcos (theta), is equal to the angle BETWEEN the force vector and the distance vector. Since the distance vector is facing the complete opposite direction of the force vector, then the angle between them will be 180 degrees.
