Energy Transfer
Energy Transformation
100
Lab #1 measured this variable for the ball, calculated by dividing distance/time.
What is the speed of the ball
100
Measuring the ball five times and finding the average reduces the effect of this factor on the results.
What is error
100
True/False: A pendulum is any mass that can swing freely.
What is true
100
Energy transfer occurred in Lab 3 when the ball hit this object.
What is the cup
100
What does GPE transform into in Labs 1 and 3?
What is KE
200
These two properties affect an object's Gravitational Potential Energy.
What is mass and height
200
The person lifting the ball to the top of the ramp gave the ball this kind of stored energy.
What is GPE
200
Galileo used the pendulum to measure this.
What is time
200
True/False: Energy transfer happens when the ball changes from GPE to KE.
What is false
200
When the KE of an object hits the air particles around it, this type of energy is being transformed into.
What is Heat/Thermal Energy
300
As the height of the ramp increased, this also increased.
What is the speed of the ball
300
GPE equals KE at this point on the ramp.
What is halfway down the ramp
300
Changing this property of a pendulum greatly affects the period of the pendulum.
What is the length of the string
300
Energy transferred to these during Lab 4 (Pendulum Lab).
What are air particles
300
Energy transforms from one form to this.
What is another form
400
This force makes the speed of the ball along the level tabletop and the speed of the ball at the bottom of the ramp the same.
What is gravity
400
The independent variable (the variable that we change) is graphed on this axis.
What is the x-axis
400
When the pendulum moves through the air, it creates this type of force as it moves against air particles.
What is friction
400
During energy transfer, the same kind of energy moves from one object to this without changing forms.
What is another object.
400
During one period of a pendulum, energy transforms from GPE to KE this number of times.
What is four times
500
If the Kinetic Energy for object A and B (which have equal mass) is the same, then this must also be the same.
What is the speed of A and B
500
The ball passed KE into the cup during Lab 3, an example of this.
What is energy transfer
500
Increasing this in a pendulum's bob increases its amount of GPE the pendulum has at its highest point, much like what we saw in Labs 1 and 3.
