CCRS: IOD – 16-19: Interpretation of Data (IOD) Determine how the value of one variable changes as the value of another variable changes in a simple data presentation
If engineers can use potential energy (height) of an object to calculate how fast it will travel when falling, can they do the reverse and calculate how high something will rise if they know its kinetic energy (velocity)? (Answer: Yes, as long as you know either height or velocity, you can calculate the other.)For what might an engineer use this information? (Answer: To create other amusement park rides besides roller coasters, in racing, or how to launch something, etc.)Why did the pendulum have the same period even when the weight started from different heights? (Answer: The period of a pendulum is only dependent on the length of the pendulum, which is consistent no matter where the weight starts.)

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.
