Potential Energy
This medieval device used gravitational potential energy to throw a large projectile at castles.
What is a trebuchet?
Kinetic energy depends on an object's mass, and this other property.
What is speed?
This form of energy transfer always travels from high to low temperature.
What is heat?
The law of energy conservation states this about energy.
What is that it cannot be created or destroyed?
What is mass?
An object that is not moving would have this much kinetic energy.
What is zero?
This form of heat transfer depends on the movement of a fluid to carry energy.
What is convection?
This type of system is does not exchange energy or mass with its surroundings.
What is an isolated system?
A 10 kg ball raised to 10 meters would have this much gravitational potential energy.
What is 981 joules?
A 20 kg mass moves at a speed of 4 m/s, giving it this much kinetic energy energy.
What is 160 J?
This form of heat transfer requires no medium, or material, for the energy to travel through.
What is radiation heat transfer?
A roller coaster that starts from rest with 1000 J of potential energy. The cart can, at most, ever have this much kinetic energy.
What is 1000 J?
A 1 kg ball raised to 10 meters would have the same energy at this amount of mass raised to 1 meter.
What is 10 kg?
The average kinetic energy of an object's particles can be characterized, or measured, by this property of the object.
What is temperature?
This material property affects how much a material's temperature will change when the material gains or loses heat.
What is specific heat capacity?
A skater goes up an down a half-pipe, as an isolated system. This can be said about the skater's total energy at each point on the ramp.
What is that it is constant?
Potential energy is always measured arbitrarily from this.
What is a reference, or zero, point.
A 1 kg object moving at 2 m/s would have as much kinetic energy as a 4 kg object moving at this speed.
What is 1 m/s?
This common substance has one of the highest specific heat capacity values.
What is water?
This term describes energy that is not lost, but rather transformed into a non-useful, chaotic form, typically due to friction.
What is thermal energy?
