What is velocity.
300
This is the formula for gravitational potential energy.

This is the energy transfers involved in a student eating lunch and then playing basketball. *Two energies involved.
What is the transfer of energy from chemical energy (stored in the food) to the mechanical energy of a moving body playing basketball.
300
If you build up enough of this, even smaller objects, like a tennis ball, and move much heavier things, like a kilogram weight.
What is momentum.
400
For a falling object, this is where it has the most kinetic energy.
What is at the bottom.
400
For a falling object, this is where its potential energy is the highest.
What is at the top.
400
This is how heat always moves..."from a _______________ place to a _______________ place."
What is from a warmer place to a cooler place."
400
This is transformation of energy in the sun, beginning with the nuclear energy of fission. *Hint: Nuclear fission in the sun creates these two types of energy that we need to live.
What is the transformation from nuclear energy to thermal energy and radiant (light) energy.
400
When two basketballs of equal mass are dropped from unequal heights, one dropped from 2 meters and the other from 4 meters, this basketball will have more kinetic energy as it reaches the ground.
What is the basketball dropped from 4 meters.
500
A 4 kg rock is thrown into a lake with a velocity of 5 m/s.
What is 50 J.
500
A 40kg student jumps off of an 8m diving board. This is his gravitational potential energy at the very top of his fall. (use 10m/s^2 for the acceleration of gravity - g=10)
What is 3200 J.
500
Heat lamps hanging above food in a serving line is an example of this type of heat transfer.
What is radiation.
500
This is the transfer of energy of an apple falling out of an apple tree (you must begin with the sun which grows the apple tree). *Hint: 6 types of energy involved.
What is the transfer of energy from the nuclear energy, to thermal and radiant energy, to the chemical energy of the apple tree, to gravitational potential energy, to kinetic energy of the falling apple.
500
These are materials that thermal energy can easily transfer through. *Double points by naming the types of materials that do the opposite, and providing an example of each.
