WGU C451 Module 2: Forces, Energy, and Motion Questions and Answers Rated A+ What is potential energy? Stored energy that has the potential to do work. How does a change in mass of an object affect the gravitational potential energy of that object? How does a change in height affect it? The greater the mass, the greater the force of gravity it exerts, so the more attracted to each other they will be. When objects are pulled further apart, the force of gravity weakens. The distance increases the...

what happens during a chemical reaction.️️one or more new compounds are formed as a result of the rearrangement of atoms. Explain why the law of conservation of energy is important in chemical reactions.️️states that matter is neither lost nor gained in traditional chemical reactions; it simply changes form. Thus, if we have a certain number of atoms of an element on the left side of an equation, we have to have the same number on the right side. This implies that mass is also conserv...

Define wave. - ANSWER-A disturbance that travels through space and time accompanied by the transfer of energy. It is a vibration, a vibration is a wiggle, and a wiggle that travels is called a wave. Waves carry energy from one place to another. Explain the difference between a transverse wave and a longitudinal wave, and give examples of each. - ANSWER-- Transverse Waves- Waves that move up and down, vibrations perpendicular to the direction the wave travels. Types: Light/electromagnetic, (ra...
