The Scientific Method
Ms. Buchanan wants to see if the type of coffee she drinks will affect her ability to grade papers. In this case, the independent variable would be _________
The type of coffee
To describe an object's motion, you should focus on the __________ and the __________.
Direction and Speed
Define Kinetic Energy
Energy that involves movement.
This type of energy is energy that is on the electromagnetic spectrum. An example of this energy would be the sun.
Radiant/Light Energy
Name a nonrenewable source.
Coal, Oil, Natural Gas
Ms. Buchanan is trying to see if she grades papers faster during the morning or during the afternoon. She is using a stopwatch to time herself. The dependent variable would be _______
The time it takes to grade papers.
True or False: If two people are pulling an object in opposite directions with the SAME amount of force, the object will not move.
True
Define Renewable Resource
A source that can be used over and over again.
When you have a fan, what kinds of energy are present when the fan is turned on? In what order is the energy transformed?
Electrical-->Thermal
Name a Renewable Source
Solar, Wind, Water
What is the first step to the Scientific Method?
Observation
A moving toy car collides with a ball that is not moving. What will most likely happen as a result of this collision?
The toy car will transfer the force to the toy ball. The ball will start to roll, and the toy car will start to slow down.
Define Mass
The amount of matter an object takes up.
This type of energy is thought of as energy stored when an object is at rest
Potential Energy
What kind of resources are thought to be better for the environment?
Renewable
True or False: A hypothesis always has to be correct.
False
A bowl of grapes is being pulled down by gravity and pushed up by the table. It is staying in place. The combination of forces acting all together on an object is called the _________
Net Force
Define Nonrenewable resources
Sources that cannot be used over and over again.
This energy happens from the flow of tiny particles in a material. These particles create a charge.
Electrical Energy
Why should we not rely on nonrenewable resources?
These resources will run out and they are bad for the environment
What is a Constant?
Something that you keep the same during the experiment.
A student is riding a bicycle on a rough surface. Then, they ride the bike on a smoother surface and notice it goes faster on the smoother surface. This is because the smoother surface has _______ friction.
Less
Define Motion
An objects Direction and Speed/Movement
Energy cannot be created or destroyed, only __________ or __________
Transformed/Transferred
