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.
The expression 'apparent motion' is used often in physics conversation. Usage of the expression apparent motion is frequently criticized, for if it is meaningful to speak of 'apparent motion' then there must also be a 'true motion', and how is that a meaningful distinction?
