What is the formula to calculate speed?
What is DISTANCE/TIME?
Is miles per hour a proper SI unit of speed?
What is no, that is the customary system?
List 4 of the forms of energy (PE and KE are a type of energy not a form)
What is Chemical, mechanical, nuclear, sound, thermal, electrical, electromagnetic?
Give an example of an exothermic reaction
What is fire, Bunsen burner etc...
Name the energy transformation that occurs when you turn on a light bulb.
What is electrical to thermal, electrical to electromagnetic, mechanical to thermal or mechanical to electromagnetic?
Short Answer--- Emily slid down the sliding board at the park. A. Where did Emily have the most potential energy?
What is at the top of the slide?
What SI unit of speed would be used for a car traveling fast?
What is km/h?
Can energy be created or destroyed?
What is no, the law of conservation of energy states this?
Given an example of an endothermic reaction
What is ice, dry ice, etc....
Give an example of an energy transformation that is mechanical to sound.
What is Clapping your hands, car crash, chopping down a tree, etc...
Short Answer--- Emily slid down the sliding board at the park. B. Where did Emily have the most kinetic energy?
What is at the bottom of the slide right before the end?
Calculate the velocity of a cyclist traveling 72 kilometers south over a period of 9 hours. Make sure to include the correct units!
What is Divide 72 by 9 and get 8 km/h south?
Thermal energy is often call the energy of __________
What is heat energy?
HEAT ENTERS IS ________________ HEAT EXITS IS _________________
What is endothermic and exothermic?
Describe the PE and KE changes on a roller coaster. Feel free to draw or explain
Label HIGHEST/ LOWEST PE AND KE, and when they are equal
What is at the top of the roller coaster PE will be highest before it goes down. Halfway down PE=KE. And the bottom right before the end of the ride, KE will be highest.
How does the number of coils impact the strength of the electromagnet?
What is the more coils means stronger magnet?
What is the difference between speed and velocity?
What is they both use distance and time but velocity also includes direction.
Can the total amount of energy in a system change depending on its surroundings. Explain why or why not?
What is no, the law of conservation of energy states that energy cannot be created or destroyed. Therefore that total amount cannot change.
You are given a wire, a 9v battery, iron nail, and some paper clips. Your job is to get as many paper clips as possible to stick to the nail on one try. With the given materials, how would you accomplish this task?
What is wrap the wire around the nail as many times as possible leaving a little bit of the wire exposed on each side. Then attach the battery to the ends of the wire.
What do you use electrical energy for?
What is charging your phone, watching TV, etc...
Short Answer--- Elena is in a raft floating in her pool. As she jumps out of the raft, she moves forward as the raft moves in the opposite direction. Explain which one of Newton’s Laws this demonstrates.
What is his represents Newton’s third law. The action is her jumping off of the raft. The reaction is the raft moving in the opposite direction.
