What type of energy does a roller coaster have at the top of the hill?
gravitational potential energy
What kind of energy does the roller coaster have at the bottom of the hill?
maximum kinetic energy
When a dog jumps on a couch, the dog transfers energy and this is done.
work
A book has kinetic energy of 4.0 J. Then it gets torn in half and has half the original mass. What is the kinetic energy of the torn book?
2.0 J
The potential energy at the top of the hill must be _______than or equal to the kinetic energy at the bottom of the hill.
greater
a rubberband this kind of energy
elastic potential
what two factors affect kinetic energy
mass and velocity
what is the formula for kinetic energy
½ mv2
what is the formula for gravitational potential energy
mgh
what is the acceleration due to gravity on earth
9.8 m/s2
what is the formula for work
force x distance
what two things are required in order for work to be done
force and distance
uranium atoms produce this form of energy
nuclear
spinning tires produce this form of energy
mechanical
friction which produces heat creates this form of energy
thermal
moving electrons on a circuit produce this form of energy
electrical
if 2 objects with similar masses are going at different speeds, which will have more kinetic energy, object with more or less speed
object with more speed
a group of interacting parts that move or work together
system
energy of position
potential
energy of motion
kinetic
fuel in a gas can has which kind of energy
chemical potential
gravitational energy is based on this factor
height
metric unit for force
Newtons
Unit for energy
Joules
ability to do work or cause changes in matter
energy
mechanical energy is
sum of an object's kinetic and potential energy
caused by the vibrations in a medium
sound
the change of one form of energy into another
energy transformation
when two objects collide, each exerts a force on the other that can cause energy to pass from one to the other
energy transfer
energy is conserved, it is not created or destroyed
conservation of energy
when types of energy are involved when a person pulls a rubberband back then releases it
potential to kinetic
