A system schema does all of the following EXCEPT
provides a tool for identifying the objects in a system.
identifies potential energy.
identifies the interactions between objects in a system.
identifies if interactions are occurring with the surroundings across a system boundary.
The kind of energy released when atoms are rearranged to form new bonds is called
phase
kinetic
chemical

potential
gravitational
kinetic
elastic
The maximum gravitational energy for an skier is
at the top of the bunny slope
at the bottom of the hill
at the top of the ski lift
none of the above.
An object has zero kinetic energy when
velocity increases.
velocity reaches zero.
velocity is constant but mass doubles.
a moving object falls to the Earth.
During the observation stations at the beginning of the year, in which of our observation stations did we experience Eph?
burning Cheeto

melting ice
Energy flow diagrams (LOL diagrams) provide an advantage over pie charts. Which of the following is NOT an advantage of LOL diagrams.
LOL diagrams provide a more quantitative energy representation than pie charts.
LOL diagrams provide a less quantitative energy representation than pie charts.
LOL diagrams show a mechanism for transfer of energy into and out of the system.
LOL diagrams show a mechanism for transfer of energy within the system.
According to the law of conservation of energy
the amount of energy at the beginning of the interaction must always equal the energy at the end of the interaction.
the amount of energy at the beginning of the interaction will equal the energy at the end of the interaction if there is friction in the system.
the amount of energy in a system at the beginning and end of an interaction will be equal unless energy is added to or lost from the system.
The difference between the starting point and the ending point is called
motion
distance
time
displacement
To calculate the average SPEED of an object, you need to know the total __________ traveled.
distance
time
distance and time
distance, time, and direction
To calculate the average VELOCITY of an object, you need to know the
distance traveled.
displacment
distance and time traveled.
displacement and time
The slope of a distance vs time graph represents the
speed
rise over run
displacement
velocity
Energy is best described as
power
the ability to produce heat
a change in motion
the ability to cause change
