Date: 10/26 Goal: I can investigate the relationship between speed at the bottom of a pendulum and height of the period of its swing. 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 =
(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.
