1. Bell ringer- What effects the energy/speed of a pendulum?
Length of line, tension, potential energy(height of drop), mass of ball

2. What did we learn yesterday?
EQ: How is calculating potential energy similar or different from calculating kinetic energy? Language objective: Tell a peer how to calculate PE and KE.

3. Calculating PE
Definition: Gravitational Potential Energy is the energy of an object’s position (height). Equation: PE=mass X Gravity(9.81)X height

4. Practice Potential
Ms. Matthews decides to break the Guinness Book of World Records for bungee jumping. She goes to the Macau Tower in China where the current record is held. After several heart-pounding seconds, she leaps from a height of 233 meters. If her weight is 86 kilograms, what would her potential energy be just prior to jumping?
Remember the EQ is PE=mass X Gravity(9.81)X height
PGE=196, J

5. Calculating KE
Definition: Kinetic energy is the energy of objects in motion Equation: KE = ½ mv2

6. Practice Kinetic
When a golf ball is hit, it travels at 41 meters per second. The mass of a golf ball is kg. What is the kinetic energy of the golf ball?
Remember the EQ is KE = ½ mv2
KE=1/2 (.045) (1681)
KE= J

7. Kahoot Remember quiz Friday Types of energy (potential and Kinetic)
