Two parts of a graph that make it identifiable as a graph.
What is the x-axis, the y-axis, labels with units for each axis and/or a title.
100
How do we measure speed?
What is distance divided by time. Also acceptable miles per hour or meters per second
100
This is something that you do when you see, hear, smell, touch or sense something.
What is an observation.
100
This causes an object to slow down.
What is friction.
100
When elastic objects are stretched they are said to have this.
What is elastic potential energy
200
In a velocity-time graph, the x axis is __________.
What is time
200
What's the difference between speed and velocity?
What is velocity tells speed and direction while speed only tells how fast an object is moving.
200
This is what you do when you make a conclusion based on an observation.
What is make an inference.
200
This is where the energy goes when an object slows down.
What is kinetic energy is converted to thermal energy through friction.
200
The amount of potential energy an object has is proportional to this.
What is the amount that it is stretched.
300
In a velocity-time graph, the y-axis is _________.
What is velocity
300
This is an arrow that describes the magnitude (the amount of something like velocity or force) and direction of an object.
What is a vector.
300
This is a type of energy that is in motion.
What is kinetic energy.
300
This is when something is negligible.
What is when it is small enough to be ignored.
300
In physics we sometimes put an imaginary frame around object to understand energy. What is this frame called?
What is the system.
400
When is it a good idea to use a line graph?
What is the time when you are looking at changes over a period of time.
400
When using the equipment that we used in lab, a negative velocity tell us this.
What is the cart or object is moving toward the sensor.
400
At what point on the E3 graph is a transfer of energy taking place?
What is wherever there is a slope not equal to zero.
400
If friction were somehow completely removed, what would happen to an object that was pushed?
What is the object would just keep going and going.
400
Energy from a system can be lost to the __________ through friction or heat.
What is surroundings.
500
See the E1 drawing on the board. Where is the velocity of the cart constant?
What is (judge discretion)
500
See the E2 graph on the board. At the circled region, is the cart speeding up, slowing down or staying at a constant velocity?
What is slowing down.
500
This is what energy diagrams show.
What is a transfer of energy.
500
In the E4 graph which object is slowing down faster?
What is object A.
500
The law of conservation of energy says that _____________.
What is energy cannot be created or destroyed.
