vocab
Something measurable that can change
Variable
Energy of motion
kinetic
A unit used to measure energy
joule
When a roller coaster car is at the top of a steep slope, it has
high potential, low kinetic
When a car drives up a hill, what has been increased
potential energy
Stored energy. potential energy depends on gravity. the higher the object, the more potential energy it will have.
Potential energy
What do all forms of energy have in common
the ability to cause changes to a system
energy is
the ability to do work or make a change
When would a marble have the most potential energy
At the top of a ramp
How are potential and kinetic energy similar?
each can be converted to the other form
Energy of motion. Kinetic energy depends on an objects mass or velocity A large ball rolling will have more kinetic energy than a small ball rolling
kinetic energy
when would a marble have the most potential energy?
at the top of the ramp
Stored energy is
Potential
low potential, maximum kinetic
Kinetic energy depends on the height of an object above the ground. T/F
False
The unit used to measure energy. The amount of energy that is needed for a change within a system
Joule
When a roller coaster car reaches the bottom of a steep slope, it has
low potential, maximum kinetic
What do all forms of energy have in common?
the ability to cause changes to a system
A system is
a group of interacting or interdependent parts forming a complex whole
When an object is at rest it doesn't not have any kinetic energy. T/F
true
PE - stands for
KE- stands for
potential energy
kinetic energy
How are potential and kinetic energy similar
each can be converted tot he other form
When one type of energy changes to another type of energy
energy transformation
How can a student increase the potential energy of a marble set up to roll down a ramp?
increase the height of the ramp
potential energy is the moving energy in an object. T/F
False
