100
What was the dependent variable during the peak force cart lab?
force
100
What does this image show?
It shows an increase in mass doing less damage during a collision than speed.
100
deform
distort, bend, or change shape.
200
What was the independent variable during the peak cart lab?
mass
200
What happens when you double the speed and mass of kinetic energy
Doubling the speed causes more energy transfer and more damage, testing the elastic limits.
200
ridgid
unable to bend or forced out of shape
300
controlled variables
the variable that stays the same every time you run a test
300
What does more damage or causes more force, speed, or mass?
speed
300
energy transfer
moving energy from from object to another.
400
dependent variable
caused by the change of the independent variable
400
What axis does kinetic energy go on
the y-axis (up to down).
400
contact force
push or pull when 2 objects touch
500
independent variable
changes every time you test.
500
What goes on the x-axis?
the mass
500
During a launch, is there a kinetic energy increase or decrease?
KE increase.
500
friction
a contact force going against motion that causes reduced speed or stopping
