Mei Song Zachary Butler Physics 101L Section 6 Energy Prelab The purpose of this lab is to discover and explore total energy, kinetic energy and potential energy. Energy is a scalar quantity and comes in many different forms but we will online look at two today, kinetic and potential energy. Kinetic energy is energy associated with the object’s motion. It is easily solved using the formula KE = 1 2 m v 2 where m is the mass, v is the velocity, and KE is the kinetic energy. The other form of energy is potential energy; it is the energy store in an object and gravity gives potential energy to an object. The equation to solve potential energy is PE = mgh where m is the mass of the object, g is gravity which is 9.8 m s 2 , h is the height of the object and PE is the potential energy. Both types of energy are measure using the SI unit called the joule (J). When we want to solve for the change in potential energy we use the same equation for potential energy as above but instead we are solving for

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
