Lesson 1-3 Review
This causes objects to have a change in motion.
What is energy transfer/kinetic energy?
This term is drawn to show an average on a scatterplot graph.
What is a A line of best fit?
In any lab or investigation, a scientist/engineer must consider these factors that they want to change or control.
What are variables?
This is the main cause of any deformation on an object.
What is a force?
What is "type of material"?
This causes a change in shape or deformation.
What is force?
This tool is used to draw a line of best fit.
What is a ruler?
A variable you want to keep the same is called this type of variable.
What is a controlled variable?
Fill in the blank:
When you increase the amount of force applied on an object, the amount of deformation ___________.
What is "increases"?
This is the amount of force that an object breaks at.
What is Breaking Point?
What is an "A collision"?
In our deformation lab experiment, our class graph showed that this material deformed the most when a greater amount of force was applied to it.
What is styrofoam?
DAILY DOUBLE!
If you wanted to experiment with how the temperature of the room affects student test scores, changing the temperature of the room is this type of variable.
What is the independent variable?
A (larger/smaller) _________ amount of force is required to start elastically deforming an object.
What is smaller?
Items that can bend more with more force without permanently deforming have this type of elastic limit (high or low).
What is "high elastic limit"?
A baseball player hitting a baseball is this type of collision (A, B or C).
What is a C collision?
A graph showing the amount of deformation of an object from a certain amount of force shows a line with this type of slope when there is a larger amount of deformation.
What is "Greater"?
What is "Steeper"?
What is "Positive"?
If athletes drink gatorade, then their performance will increase because gatorade supplies energy to the body. The dependent variable of this scenario is__________________.
What is "increase athletic performance"?
This material (1 styrofoam, 2 styrofoam, 1 wood stirrer, 2 wood stirrers) deformed the least when more force was applied to it.
What is "2 wood stirrers"?
Fill in the blank:
All objects break when (the same or a different) ______ amount of force is applied to it.
What is "different" amount of force?
A collision with any object will all experience this effect.
What is a change in motion.
This is the best place to put a line of best fit.
What is "There should be an equal number of points above and below the line."
Independent Variable: Amount of time spent practicing
Dependent Variable: Increased chance of winning a basketball game
The question (hypothesis) of study is ________________________________________.
Does the amount of time spent practicing increase or decrease the chances of winning a basketball game?
In the article you read about metals undergoing a deformation test, this material was able to withstand more force before it permanently deformed.
What is steel?
A material will have this effect if the amount of force exceeds its elastic limit.
What is "permanently deform"?
