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. The probability of making a type II error is Î², which depends on the power of the test.
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.
Potential energy is the stored energy an object has because of its position or state. A bicycle on top of a hill, a book held over your head, and a stretched spring all have potential energy. How is it different from kinetic energy? Potential energy is stored energy while kinetic energy is the energy of motion.
