These show the POSITION in a motion map
What are the dots?
100
Velocity has this. Speed does not.
What is direction?
100
This is the definition of acceleration
What is the time rate of change of velocity?
100
This is a statement of the relationship between the manipulated and responding variable
What is a claim?
100
This has a volume greater than the product of its dimensions
What is the tardis?
200
These show VELOCITY on a motion map
What are arrows?
200
This is the equation for average velocity
What is "Average Velocity= change in position/change in time"
200
Acceleration is the slope of this graph
What is velocity vs time?
200
This is a predictive statement that can be tested, and which includes a scientific reason for the prediction.
What is a hypothesis?
200
This should be avoided in the presence of a weeping angel.
What is blinking?
300
A change in position
What is displacement?
300
Velocity is the slope of this graph
What is Position vs Time?
300
These are the units of acceleration
What is meter per second squared?
300
This variable is always placed on the horizontal (x) axis
What is the manipulated variable?
300
This will fall when the question is asked. (Hint: It has nothing to do with balls or ramps.)
What is silence?
400
The PATTERN of the dots in a motion map of a ball falling
What is "starting close together and getting further apart, uniformly" (drawing accepted).
400
A dog started at rest at 30m. At t=5min the dog was at a position of 60m and was moving at 1m/s ... This is the dog's change in velocity from 0 to 5 minutes.
What is 1m/s?
400
This is the equation for calculating average acceleration
What is change in velocity divided by change in time?
400
This part of a conclusion contains an explanation based on scientific concepts and logical thought.
What is reasoning?
400
This is a drawing of a position-time graph that depicts the tardis traveling forwards in time speeding up, and then back to its initial position at a constant speed (Hint: This is not possible without a tardis)
What is a sideways smile? (drawing accepted!)
500
This is the CHANGE in the acceleration of a falling ball over time, before it reaches the floor
What is zero?
500
THIS DESCRIPTION OF MOTION is for an object whose position is proportional to the square of time
What is speeding up at a constant rate?
500
A ball is thrown into the air and falls back down. During the time when it is in the air, its acceleration changes like THIS
No change. Acceleration remain constant
500
The acceleration vs time graph of a ball rolling across the floor away from a motion detector, slowing down
What is a constant flat line at negative acceleration
500
A dalek starts rolling down a ramp at t=0. Its average velocity is 4m/s. The ramp is 8m long. This answer is the instant in time when the dalek's average velocity is equal to his instantaneous velocity.
