-Quantitatively and qualitatively define kinetic energy and gravitational potential energy.
-Review the law of conservation of energy and relate it to changes in the types of energy an object possesses as it moves.
-Explain how conversions from one type of energy to another can be helpful in real-life situations.
energy - the ability to do work.
gravitational potential energy (PEG) - the stored energy of an object due to its position relative to a reference point on Earth; is equal to the mass of an object multiplied by the acceleration due to gravity multiplied by the height of the object relative to the reference point.
kinetic energy (KE) - the energy of motion; equal to one half times mass times the square of the velocity of an object.
law of conservation of energy - energy is never created or destroyed, it is transferred or transformed from one form to another.
potential energy - stored energy that can come in a variety of forms such as spring, gravity, and chemical.
The Physics in Motion teacher toolkit provides instructions and answer keys for study questions, practice problems, labs for all seven units of study. GPB offers the teacher toolkit at no cost to Georgia educators. It will be available in September 2018. To preorder your teacher toolkit, complete and submit this form to request the teacher toolkit. You only need to submit this form one time to get materials for all seven units of study.
