at the bottom of the hill
The charges of protons, neutrons and electrons
Electric Potential Energy
In the Hot Wheels lab, at what point on the track did the car have the least kinetic energy?
At the highest point
Ken is sending a slinky down the stairs of the dream house. What kind of energy is stored in the coils of the slinky?
The energy of an object held high above the ground that depends on gravity, mass and height, is called ___________ Potential Energy
Gravitational
When the chemicals in a glow stick are mixed together, a chemical reaction causes the chemical potential energy to be released as ________ energy
Light
The glow of a lamp when it is switched on
Kinetic Energy due to Light
What kind of energy is used by a Van De Graaff Generator?
electric potential energy
Ken is studying for his science quiz. He needs to remember the charges of protons, neutrons, and electrons. Can you help him out?
Protons have a positive charge
Neutrons have a neutral charge
Electrons have a negative charge
In Electric Potential Energy, objects with opposite charges __________ each other, and objects with like charges __________ each other
attract, repel
When two magnets are placed next to each other with the negative poles facing each other, the magnetic potential energy will be released as Kinetic Energy due to _______
Motion
A guitar string being plucked
Kinetic Energy due to Sound
What kind of energy was stored in the Hydrogen Peroxide mixture in the Elephant's Toothpaste Lab?
Chemical Potential Energy
Ken puts the south pole of one magnet to the north pole of another magnet. Why do these two ends stick together?
Because opposites attract
Elastic potential energy depends on 2 things. What are they?
spring constant (stretchiness) and distance streched
When a campfire burns, it releases different types of Kinetic Energy. What are three types?
Light. Sound, Heat/Thermal, motion
Energy stored in the bonds between Oxygen and Hydrogen in Hydrogen Peroxide
Chemical Potential Energy
When we were trying to determine the concentration of the mystery hydrogen peroxide solution, what type of energy was the dependent variable?
Thermal/Heat
Ken jumps off the roof of the dream house onto a trampoline! Explain how his energy changes as he leaves the roof and travels down into the trampoline and back.
His gravitational potential energy gradually changes to kinetic energy, then when he hits the trampoline his energy changes to elastic, then kinetic then gravitational as he comes back up.
