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 energy cannot be created nor 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 does not exchange energy or mass with its surroundings.
What is an isolated system?
This is the equation that is used to determine the amount of potential energy.
What is m*g*h ?
A 20 kg mass moves at a speed of 4 m/s, giving it this much kinetic 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 starts from rest with 1000 J of potential energy. If the cart is an isolated system, its kinetic energy will be limited to this amount.
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?
The law of energy conservation states that, for an isolated system, this energy is constant.
What is total energy?
Potential energy is always measured arbitrarily from this point.
What is a reference point.
This is the equation for calculating kinetic energy.
What is (1/2)*m*v^2 ?
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?
