Work
100
Energy of motion
What is kinetic energy
100
The sum of all the KE and PE that a roller coaster has
What is mechanical energy
100
Units of GPE and KE and work
What is Joules(J)
100
Doubling the mass of an object does this to the KE of an object
What is doubles
100
I push on a wall. Am I doing work, explain.
What is no because the wall does not move.
200
Energy stored in an object as it is lifted
What is gravitational potential energy
200
Where is all the ME=PE in a roller coaster ride
What is at the top
200
Doubling the mass causes the GPE to do this.
What is doubles
200
Doubling the velocity of an object does this to the KE
What is quadruples it
200
The three things that must be true for work to be done.
What is 1. There has to be a force 2. Force causes object to move 3. Force ans motion are in the same direction.
300
energy released when a cookie is eaten
What is chemical potential energy
300
The GPE is transformed into what kind of energy as it starts to descend
What is kinetic energy
300
What are units of height and distance
What is the meter(m)
300
This is the KE of a 2kg object that has a velocity of 4m/s KE = 1/2mv2
What is 16J
300
This is transferred to an object when work is done to it.
What is energy
400
energy stored by something that can be stretched or twisted
What is elastic potential energy
400
Where in the roller coaster ride is ME=KE
What is at the bottom
400
What is the GPE of an object that has a mass of 10kg if you raise it 2m. (g=9.8 m/s2) GPE=mgh
What is 196J
400
This is the KE of a 6kg object traveling with a velocity of 6m/s. KE=1/2mv2
What is 109J
400
This is how much work is done when a box is pushed with a force of 200N causing the box to move 4m.
What is 800J.
500
The sum of all KE and PE
What is mechanical energy
500
If 9800J were stored in a 100kg object as it was lifted, how high was the object lifted? h=GPE/mg
What is 10m
500
These are two examples of KE on the atomic level
