Energy and Motion INTRODUCTION Movement, movement, movement! Everywhere we look there is movement. That movement is governed by the interaction of forces and the conservation of energy. Force can be calculated using the mass of an object and its acceleration. Frequently there is more than one force acting on an object at a time. The net force looks at the sum of the forces and determines the impact on the motion of the object. Three forms of energy will be examined in your lab today. Kinetic energy is the energy of motion. Potential energy is the energy of position. And thermal energy is heat energy, including the heat produced from friction forces. In today's lab you will investigate a little about forces and motion and then look at how Energy is conserved during motion. Finally, you will use what you have learned to predict and investigate the motion of your marbles on the hot wheels track. LEARNING OBJECTIVES After completing this experiment, you should be able to do the following: 1. Describe the interaction of forces that govern motion. 2. Explain how energy is converted between the different forms but still conserved. 3. Predict and explain the interaction of two
