The Energy of  a Climbing Fall

2/26/2018

0 Comments

 
Last week we started a lab in which we will calculate the mechanical, potential and kinetic energy present and transferred during a a climbing fall to determine the maximum height from which our climber can fall and still survive. Over the next couple of days we will keep testing our hypotheses and try to create the safest possible system for our climber.

Mechanical Energy

2/22/2018

Today we did a card sort to identify the different types of potential energy as well as their relationship to kinetic energy and mechanical energy. Mechanical Energy is the total amount of energy in the system. It can be expressed by the equation Mechanical Energy = Kinetic + Potential Energy

Energy!

We began our energy unit today. One of our examples of energy was a Newton's Cradle. We made predictions about how it work and why it worked. We also made a Newton's Cradle out of bowling balls to see if a larger version behaved the same way. Newton's Cradles clearly demonstrates the "Law of Conservation of Energy" which states that energy isn't created or destroyed, it just changes form
