Newton
Define Newton's Third Law of Motion. Give an example.
What is for every action there is an equal and opposite reaction? Newton's Third Law of Motion.
Name six forms or types of energy. You cannot use the major categories of potential or kinetic in your answer.
What is electromagnetic energy; thermal energy; nuclear energy; chemical energy; gravitational potential energy; elastic potential energy; electrical energy; magnetic energy; mechanical energy, etc.
SI units for speed are written as
What is kilometers/hour? What is meters/second?
SI units for speed are never miles/hour!
You turn the light on in the house. Name the three forms of energy associated with this energy transformation.
What is electricity causing the light to come on and produce light or radiant energy and thermal energy the heat the at is generated because of the light.
The electricity transforms into light and heat.
True or False - ounces are SI Units for a liquid or solid.
What is false, they are US Standard Units for measurement. They are NOT SI Units.
Which law of motion is F=ma?
Newton's Second Law of Motion.
Emily is sliding down a sliding board. Explain where she has the most potential energy and where she has the most kinetic energy when sliding down the sliding board.
She has the most potential energy at the top of the sliding board. Her kinetic energy increases as she moves down the sliding board towards the bottom. Her highest kinetic energy would be when her velocity is the fastest near the bottom of the slide.
There are three charges found in an atom. List the charges and their associated parts.
What are positive protons?
What are neutral neutrons?
What are negative electrons?
How do plants use energy from the sun?
Plants generate sugar (chemical energy) using CO2, sunlight and water during the process of photosynthesis.
Earth is a giant or massive form of this energy.
What is magnetic energy?
A rocket is sitting on a launch pad. The fuel ignites and the rocket begins to move. Name the action and the reaction.
The action is the fuel igniting and the reaction is the rocket moving away from the Earth into the atmosphere.
Name the chemical reaction that occurs when energy is released during the reaction.
What is an exothermic reaction?
List just one of the SI units you could use when measuring the volume of a liquid with a graduated cylinder.
What are liters? What are milliliters? What are centiliters? etc.
In order, list the energy transformations that occur when you turn on a flashlight. We start with chemical energy stored in the battery . . . . .
What is chemical potential energy stored in the battery, the flashlight switch it turned on using mechanical energy from a human hand, radiant and thermal energy are produced when the electricity causes the light to light up and create heat (thermal energy).
What tool would be used to remove sand from a mixture of sand and water.
What is filter paper?
Frank jumps into a raft in his pool. As he jumps, he moves forward as the raft moves in the opposite direction. Which of Newton's Laws of Motion best explains what happens to Frank and the raft?
Newton's Third Law of Motion states that for every action there is an equal and opposite reaction. When Frank steps off the raft the raft moves in the opposite direction Frank is moving.
What is an endothermic reaction?
Carbon (C) has an atomic number of 6 which means that Carbon has
Carbon has 6 electrons and 6 protons.
Explain how a generator in an electrical generating plant creates electricity? Use your knowledge of energy transformations.
Mechanical energy from a turbine turns a shaft in the generator which causes magnets surrounding copper wire to spin around the wire and create electricity!
An object with a higher temperature has a _____ amount of ________ energy.
What is has a greater amount of kinetic energy?
Name the four types of friction. Give examples for each type of friction.
What is static friction, fluid friction, rolling friction and sliding friction? Box sitting on floor, swimming in a pool, skateboard moving across the pavement and sliding a box across the floor.
True or False - Motion can occur without force? Explain your answer.
This is false. Force is necessary to create motion. An object in motion.
Velocity is speed with a direction. Calculate the velocity of a person traveling 90 km/hr. south over a period of 3 hours. Show your calculation! Speed = distance/time.
90 km/hr south divided by 3 hours = 30 km/hr south. Do not forget the direction (south)!
If you are given a battery, wire, iron nail and iron staples how could you increase the amount of magnetic energy so you could pick up more staples. Think about it!!
What is wrap the wire around the iron nail and attach the wire to the battery so that the nail would become magnetic to pick up the staples. The more wire that is wrapped around the nail the more staples that can be picked up.
Explain how you can increase an object's gravitational potential energy.
What is increase the height of the object from the surface of the ground?
