Lab #1:  

Law of Conservation of Energy – the transformation of stored energy to moving energy:  potential to kinetic energy

 

 

 

Student Handout:  Energy Skate Park Basics

 

Learn more about energy due to location/position (Potential Energy) and moving energy (Kinetic Energy)

Learn the two formulas for Energy:  Potential Energy and Kinetic Energy

NOTE THAT THE UNITS FOR ENERGY ARE JOULES

PE = m g h

m = mass

g = gravitational acceleration (aka g = -9.8 m/s^2)

h = height

KE = 1/2 mv^2

m= mass

v=velocity (m/s)

Lab #2:  

Learning Objectives:  Pendulum Lab

After this activity, you should be able to:

  • Explain the concepts of potential and kinetic energy.
  • Use the concepts of kinetic energy, potential energy, and conservation of energy to perform an experiment to determine an object’s velocity.
  • Describe how the concepts of conservation of energy, kinetic energy, and potential energy are used extensively in engineering design.
