Energy Transfer Experiment: Gravitational Potential Energy to Kinetic Energy

Does a falling object have potential energy or kinetic energy or both? In other potential energy experiments, we demonstrated the Law of Conservation of Energy: energy can neither be created nor destroyed, but instead, energy transfers from one form to another. In this investigation, we will take a look at the role of gravity in energy transfer.

Introduction

The law of conservation of energy tells us that energy can neither be created nor destroyed. Instead, it changes from one form of energy to another. Potential energy is energy that is stored in an object. Potential energy can transfer into other forms of energy, like kinetic energy. Kinetic energy is energy in an object because of its motion.

Exploration

Acceleration of an object is dependent upon two variables – the net force acting on the object and the mass of the object. Using a Full-Atwood’s Machine you will explore the relationship between these variables to understand Newton’s Second Law of Motion.

Exploration

What is velocity? Velocity is often defined as speed with direction and speed is often defined as how fast or slow an object is traveling. But what exactly does being fast or slow mean? How can we represent an object’s velocity with an equation, graph, or other model? What is acceleration?

Exploration Part 1

Previously you learned that the net force acting on an object is related to the object’s motion. The net force determines whether the velocity of an object will change. This is described in Newton’s First Law of Motion:

“An object at rest will remain at rest or an object in motion will remain in uniform motion unless acted upon by an outside force”.
