Miscellaneous
100
The energy that moves objects. The energy that would be used to push a chair in.
Mechanical energy
100
A soccer ball rolling until it stops
Kinetic -> potential
100
A basketball sitting on the rim before falling into the hoop has mostly which type of energy?
Potential
100
The energy of motion.
Kinetic energy
100
A force that opposes motion between two surfaces in contact. Makes objects slow down and eventually stop.
Friction
200
The energy that is stored in the chemical composition of matter. Food and fuel are the most common source.
Chemical energy
200
Turning on a lamp
Electrical -> light
200
An arrow released from a bow, travelling toward a target has mostly which type of energy?
Kinetic
200
Stored Energy. The energy an object has due to its position, molecular arrangement, or chemical composition.
Potential energy
200
A force that pulls objects downward towards the center of the earth.
Gravity
300
The energy from the movement of particles in matter (heat).
Thermal energy
300
Fireworks exploding in the sky
Chemical -> light OR chemical -> sound
300
An arrow released from a bow, travelling toward a target has mostly which type of energy?
The sphere with more mass (because it is heavier)
300
In the energy skate park, what happens to potential energy as the skater travels down the ramp?
It decreased
300
The sum of all of the energies within a system. Never changes.
Total energy
400
Results from the vibration of particles in a solid, liquid, or gas.
Sound energy
400
Electric guitar
Electrical -> sound
400
There are two rocks of the same mass. One is at a height of 20 meters and the other is at a height of 30 meters. Which has more potential energy?
The rock at 30 meters
400
In the energy skate park, what would cause the skateboarder to fly off the ramp at a constant speed and direction (think friction and gravity)?
No friction, no gravity
400
Energy has the ability to change between different types and can transfer from one object to another.
Energy transfer
500
Energy transmitted through space in waves. Electricity, light, and x-rays are common examples.
Electromagnetic energy
500
Food being digested
Chemical -> mechanical
500
Which has more kinetic energy? A runner travelling at 15 mph or a runner travelling at 12 mph?
The runner travelling at 15 mph
500
In the energy skate park, what would cause the skateboarder to travel back and forth forever without stopping (think friction and gravity)?
No friction, normal gravity
500
Energy cannot be created or destroyed, it only transfers forms between objects.
Law of the conservation of energy
