Physics Questions & Answers Acceleration - CORRECT ANSWER- The rate at which the velocity of an object is changing. Acceleration of an object may be a change in direction or a change in speed (slowing down or speeding up). Applied Force - CORRECT ANSWER- A push or pull on an object. Average Speed - CORRECT ANSWER- A measure of the distance traveled in a given period of time. Balanced Forces - CORRECT ANSWER- Produce no change in the motion of an object and the net force is equal to 0. Chemical Energy - CORRECT ANSWER- Energy stored in the bonds of chemical compounds (atoms and molecules). It is released in a chemical reaction. Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy. Elastic Potential Energy - CORRECT ANSWER- Stored energy as a result of stretching or compressing. Electrical Energy - CORRECT ANSWER- Energy created by electrons moving through an electrical conductor.
