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.
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
Finally bringing an ending to our force and motion unit, we discussed the exam in class today. Tomorrow we begin our energy unit.
Our Force and Motion unit is complete, next week we begin Energy!
Your Force and Motion Exam is tomorrow. Use the videos below to review the skills that will be on the exam. Also, we played Force and Motion Jeopardy in class today, use this link to challenge yourself and review on your own.
The Force and Motion Exam will be Thursday. Attached are two different review packets you an use to help you study.
