What are the two main categories of matter? Classifying Matter Matter can be classified into several categories. Two broad categories are mixtures and pure substances. A pure substance has a constant composition. What can elements and compounds have in common? On first glance, elements and compounds might appear different, yet they share many similarities, like […]
What is the relationship between kinetic and potential energy and speed?
What is the relationship between kinetic and potential energy and speed? The following equation is used to represent the kinetic energy (KE) of an object. This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic […]
