True or False: The Scientific Method is linear and meant to be followed step by step every time
False
|
What are the two main types of energy and define them
Kinetic: movement
Potential: stored energy due to interactions between objects or particles |
What types of energy are involved in stretching a rubber band then releasing it to fly through the air (2 types of energy)
Elastic Potential Energy transforms into kinetic energy
|
A chemical reaction releases this type of energy
Chemical Potential Energy
|
What is the Law of Conservation of Energy?
Energy is neither created nor destroyed, it only changes form
|
|
What is a hypothesis?
A possible explanation for an observation that can be tested by scientific investigations.
|
What is Energy?
The ability to cause change or the ability to do work
|
When a box is lifted up off the ground list two types of energy that increased.
Kinetic energy
Gravitational Potential Energy |
What are the two main factors that effect gravitational potential energy?
Height and weight/mass
|
What is friction
a force that resists the sliding of two surfaces that are touching
|
|
What is a Conclusion?
A summary of the information gained during the experiment from testing the hypothesis
|
What is work and how is it related to energy?
The transfer of energy that occurs when a force is applied over a distance.
It is transferring energy |
Friction always transforms energy into what type of energy? Define this type of energy
Thermal Energy: energy due to the motion of particles that make up an object
|
What are the two main factors that determine the amount of kinetic energy?
Speed
Weight/Mass |
What are sound energy and radiant energy? Which one can travel through space?
Sound energy is energy that sound carries
Radiant energy is energy carried by electromagnetic waves Radiant energy can travel through space |
|
Name at least 3 different ways to test an experiment
design an experiment, make a model, observe, research and analyze, etc.
|
Explain the difference between a scientific theory and a scientific law
A theory tries to explain why something occurs while a scientific law states that something will occur under certain circumstances
|
What are three types of energy involved in making popcorn in the microwave
The microwave is powered by electric energy that it transforms into radiant energy which produces thermal energy in the popcorn kernel causing it to change into popcorn
|
Name 3 types of potential energy
Gravitational, Elastic, Chemical
|
What is the difference between nuclear energy and chemical energy?
Nuclear energy is energy in the nucleus of an atom while chemical energy is energy in the bonds between atoms.
|
|
List the steps of the scientific method
Be curious/ask questions, make inferences/hypothesis/predictions, test hypothesis, analyze results, draw conclusions, publish results
|
Define Waste Energy and what form of energy it most often takes
Energy that cannot be used which is most often thermal energy because every time energy changes form some thermal energy is always released.
|
When a light is turned on it is powered by ____________ energy and produces _________ and ___________ energy.
electric
radiant and thermal |
What happens when energy is used?
It changes form
|
What type of energy does your body use to move?
It uses chemical energy it transformed from chemical potential energy
