Chapter 2 Review Forces and Motion

This is a review of content related to forces and motion that 8th graders at LKMS should know.

AB
What is position?It is a point in space of an object compared to its starting point.
What is acceleration?It is a change in speed over a certain time.
What are some examples of acceleration?Positve (speeding up), Negative (slowing down), change direction, or have Zero (going the same speed)
What is deceleration?It occurs when the change in speed or acceleration is in the negative direction
What is AVERAGE speed?It is the TOTAL distance traveled divided by the TOTAL time traveled
What is INSTANTANEOUS speed?A speed of an object at a specific point in its journey
What is slope?The ratio of rise over run.
What does a steep upward slope indicate?A greater speed
What does a downward slope indicate?A speed that is slowing down
What is a scientific model?Something that visually shows how one variable relates to another
What is a conceptual model?It is descriptive visual like the model of the solar system
What is a physical model?It is something we can feel, touch and see. They are often made as scale models
What is a graphical model?It shows a graphical relationship between 2 variables
What is the rise?The increase or decrease on the y axis or the dependent variable
What is the run?The increase or decrease on the X axis or independent variable
How can you determine the speed using a position vs time graph?You could divide the distance by the time.
How is a strong relationship shown on a graph?When a small change in one variable makes a big change in another one
How is a weak relationship shown on a graph?When a big change in one variable has little affect on another one
How is an inverse relationship shown on a graph?When one variable increases, the other one decreases (they go in the opposite direction)
How can you tell when there is no relationship on a graph?The graph looks like a collection of dots (the points are scattered)
If a squirrel can run 2 meters in one hour, what is his speed in meters per minute?0.03 meters per minute
If there are 2.54 centimeters in one inch, how many centimeters are there in 3.5 inches?8.89 centimeters
What is displacement?How far away an object is from its original position
