Types of Energy
This is the energy an object possesses because it is in motion.
What is Kinetic Energy?
This is thermal energy moving from a warmer object to a cooler object.
What is heat?
These are the three temperature scales.
What is Fahrenheit, Celsius, and Kelvin?
This is the unit of Work.
Joules
These are the equations for gravitational potential energy and kinetic energy.
What is EG=mgh and EK=1/2mv2?
This is the energy an object possesses because it has been lifted up in a gravitational field.
What is Gravitational Potential Energy?
These are the three ways heat is transferred.
What is conduction, convection, and radiation?
This is -68.15ºC converted to Kelvins.
What is 205 K?
This is the equation for Work.
What is W=Fd?
This is the KE of a 1.5 x 106 g car going at a speed of 30.0 mph.
What is 130,000 J?
This is the energy contained in any object that has been stretched or compressed.
What is Elastic Potential Energy?
Soup warming in a pot on the stove is an example of this kind of heat transfer.
What is convection?
This is 75.2ºF converted to degrees Celsius.
What is 24ºC?
A football player exerts a force of 45.2 lb to drag a sand bag 1,520 ft across a football field. How much work does the player do?
What is 93,200 J?
A 2,000 g hammer has 7.85 J of gravitational potential energy. This is the height of the hammer above the ground.
What is 0.4 m?
This is energy released from the nuclear processes of fission or fusion.
What is Nuclear Energy?
The tip of an iron poker sitting in a fire is an example of this type of heat transfer.
What is conduction?
This is 471.29ºF converted to Kelvins.
What is 517.2 K?
A 1.00 x 104 g object experiences a force which causes it to accelerate at 5.00 m/s2, moving it a distance of 0.124 mi. This is the work done by the force.
What is 9980 J?
A 100.0 g apple is dropped 1.00 m. This is the speed the apple hits the ground with.
What is 4.43 m/s?
These are the nine types of energy.
What is Gravitational Potential Energy, Kinetic Energy, Electrical Energy, Thermal Energy, Elastic Potential Energy, Acoustic Energy, Electromagnetic Radiation, Chemical Potential Energy, and Nuclear Energy?
Heat lamps hanging above a buffet table at a restaurant are examples of this type of heat transfer.
What is radiation?
This is 305 K converted to degrees Fahrenheit.
What is 89.33ºF?
A group of friends applies a cumulative force of 242.8 lbs to push a car to the nearest gas station. This the distance the car traveled given that the work done on the car was 2.35 x 105 J.
What is 217 m?
A 6.00 x 105 g boulder falls from the top of a cliff and hits the ground with a speed of 153.5 mph. This is the height of the cliff.
What is 240 m?
