Force Me
This is the ability to cause change.
What is energy?
KE depends on these two things.
What are mass and velocity?
This increases as an object gets higher.
What is gravitational potential energy?
This is what the law of the conservation of energy says.
What is energy cannot be created nor destroyed, only transferred or transformed?
This is the type of energy that you feel from a hot object.
What is thermal energy?
This is the amount of energy required to raise the temperature of 1 gram of water 1 degree Celsius.
What is a joule?
A skier has the most KE at this point on the hill.
What is the bottom?
This is highest when a rubber band is fully stretched.
What is elastic potential energy?
When a snowboarder has gone a quarter of the way down a hill, this percentage of his PE has converted into KE.
What is 25%?
This is the type of energy that holds protons and neutrons close together in an atom.
What is nuclear energy?
If a force of 100 N is used to push a box 9 meters across the floor, this is how much work was done.
What is 900 J?
A 5 kg ball moving at 5 m/s has this much kinetic energy.
What is 62.5 J?
This is the GPE of a gymnast with a mass of 50 kg that is standing on a balance beam that is 125 cm tall.
What is 612.5 J? (or 625 J if g=10 m/s/s)
This is one of the things that all the PE and KE have converted to once a roller coaster reaches the bottom of a hill and comes to a complete stop.
What are light energy (sparks), thermal energy (heat from friction), sound energy (squeak), or kinetic energy of the air particles/surroundings?
What is chemical energy?
What is force?
An avalanche gets the kinetic energy to move from these two sources.
What are the gravitational potential energy of the snow and the kinetic energy of the disturbance?
This is the kind of potential energy stored in your body.
What is chemical energy?
At a certain point on a hill, ignoring friction, a car's PE is 15,600 J and its KE is 11,200 J, which means this is its mechanical or total energy.
What is 26,800 J?
This is the kind of energy that we see is released when a fire burns.
What is electromagnetic energy (or light energy)?
This is how much work was done by gravity on a 50 kg diver diving from the 20 m high dive.
What is 9,800 J? (or 10,000 J if g=10 m/s/s)
A 25 kg box moves a distance of 10 m in 5 seconds. This is its kinetic energy.
What is 50 J?
A rock that is half the mass of a boulder would have to go to this many times the height of the boulder to have the same GPE as the boulder.
What is two times?
An herbivore receives chemical energy from the plants they eat. The plants receive light energy from the Sun. This is where the Sun gets its energy.
What is nuclear energy from the fusion of hydrogen atoms into helium atoms?
This is the kind of energy that a diver loses as they fall to the water.
What is potential energy?
