When the null hypothesis is false and you fail to reject it, you make a type II error. The probability of making a type II error is Î², which depends on the power of the test.You can decrease your risk of committing a type II error by ensuring your test has enough power.hen the null hypothesis is false and you fail to reject it, you make a type II error.

Kinetic energy is energy of motion. The kinetic energy of an object is the energy it possesses because of its motion. The kinetic energy* of a point mass m is given by. Kinetic energy is an expression of the fact that a moving object can do work on anything it hits; it quantifies the amount of work the object could do as a result of its motion.
An object has kinetic energy when itâs in motion. The amount of kinetic energy an object has depends on its mass and speed. Potential energy, on the other hand, is a stored energy when an object is at rest. It describes how much work the object could do if set into motion. Itâs an energy we can generally control. When an object is set into motion, its potential energy transforms into kinetic energy.
