OH NOES! MATH!
100
Draw a speed vs time graph showing an object that is stopped
The graph should have a flat line at 0
100
This is an object used for comparison to see if something is moving.
What is reference point?
100
This is the rate of how far something can move in a unit of time.
What is speed?
100
The rate at which velocity changes with time is called this.
What is acceleration?
100
A runner covers 100 meters in 50 seconds. This is her speed.
What is 2 m/s?
200
Draw a distance vs time graph showing an object that is stopped
The graph should show a flat line anywhere on the graph
200
This is the basic unit of length in the metric system.
What is the meter?
200
Give a unit that can be used to measure speed.
Any unit of distance divided by a unit of time.
200
If you are going 30 miles per hour, and you slow down to 20 miles per hour, this will be the sign for your acceleration.
What is negative?
200
A runner runs at a speed of 5m/s. This is how far they go in 60 seconds.
What is 300 meters?
300
Draw a speed vs time graph showing an object that is slowing down
The graph should have a downward sloping line
300
These kinds of objects make good reference points because they themselves typically don't move.
What is stationary objects?
300
Speed is not always constant, so we often calculate this by dividing total distance by total time.
What is average speed?
300
These are the values on the y axis and x axis of a graph whose slope shows you acceleration.
What is speed and time?
300
A sled is going down a snow-covered slope at 12m/s. How long will it take the sled to get to the bottom if the distance to the bottom is 36m?
What is 3 seconds?
400
Draw a distance vs time graph showing an object that is slowing down
The graph should show a curved line starting out steep and ending flat
400
This is what you get if you calculate the slope of a distance vs. time graph.
What is speed?
400
These two things make up velocity.
What is speed and direction?
400
Give any unit for acceleration.
What is any unit that has a unit of distance divided by a unit of time squared.
400
A man walks at 0.5 m/s, then accelerates to a velocity of 0.6 m/s in 1 second. This is his acceleration.
What is 0.1 m/s2?
500
Draw a distance vs time graph showing an object that is speeding up
The graph should show a curved line that starts out flat and gets steep
500
This is what we call when the distance between one object and another object is changing.
What is motion?
500
Velocity is an example of this, anything that has a magnitude and direction.
What is a vector?
500
This is how you can accelerate even if you are moving at constant speed.
What is change direction?
500
A train traveling at 10 m/s slows down to a complete stop in 20 seconds. This is the acceleration of the train.
What is -0.5 m/s2?
