TB. P. 360 Part A #1-4c

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 =

(PEgrav) 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 PEgrav 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/s2

• 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 v2

• ½ = 0.5 or half (constant with no units)• m = mass of object (kg)• v2 = velocity2 or velocity x velocity (m/s)• KE units are Joules because we are measuring

energy.

same height? Why?

Distance stays the same and height changes

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?

Date: 9/16 Goal: I can develop a roller coaster for a particular group of riders.
