What is a quantized value? Quantized: In quantum mechanics, the concept that a system cannot have any possible energy value but instead is limited to certain specific energy values (states). The states depend on the specific system in question. How is a piano An example of a quantized system? When you play a piano, you […]

What is the force of a car crash? force equals mass times acceleration. In this case, the acceleration is (v – 0)/t, where t is whatever time it takes car A to come to a stop. The car exerts this force in the direction of the wall, but the wall, which is static and unbreakable, […]
