Potential Energy Potential energy (PE) = stored energy of position possessed by an object Examples: The ball of a demolition machine A stretched bow Coconuts in a tree There are 2 types of potential energy:

1. Gravitational Potential Energy Gravitational potential energy = (PE grav ) the energy stored in an object as the result of its vertical position or height. The energy is stored as the result of the gravitational attraction of the Earth for the object. Example: The PE grav of the massive ball of a demolition machine is dependent on two variables - the mass of the ball and the height to which it is raised.

Kinetic Energy Kinetic Energy = (KE) energy of motion There are many types of kinetic energy, but we are going to focus on only one type: energy due to motion from one location to another. Examples: – Roller coasters going downhill – Skateboarding up and down a half-pipe – Wind

Calculating GPE GPE = mgh m = mass of object (kg) g = acceleration due to gravity – on Earth it equals 9.8 m/s 2 Δ h = change in height of object (meters) PEgrav units are Joules(J) because we are measuring energy. Recall the weight (w) is mass x gravity (w = mg). As a result, PEgrav can also be calculated if you are given weight. – PEgrav = wΔh

Calculating KE KE = ½ m v 2 ½ = 0.5 or half (constant with no units) m = mass of object (kg) v 2 = velocity 2 or velocity x velocity (m/s) KE units are Joules because we are measuring energy.

Title: 10/7-8 Homework: In your notebook, write a summary of the relationship between speed at the bottom of a ramp and both height and distance of the ramp. Based on the results from your activity. Did the height or distance change have a greater effect on the speed at the bottom of the ramp? (5-10 sentences) This is on the weekly schedule on Mr. Stoll’s web page

10/9 xXx Movie Calculation Vin Deisel is trying to catch a jet boat to dismantle a bomb. He has to drive his GTO 50 miles to catch the boat. The boat is traveling 10 miles up river at a velocity of 40 mile per hour. 1.How do you calculate the average velocity at which 50miles 10miles the GTO must travel? 40mi./h 2. Is this possible in real life? Why or Why not?
