Energy
List at least four different kinds of energy.
All possible answers: kinetic, gravitational potential, elastic potential, chemical potential, electrical, thermal, electromagnetic radiation, nuclear, acoustic
Give an example of an inelastic collision.
Many possibilities.
Energy can neither be created nor destroyed, only changed in form
Describe inelastic collisions.
An inelastic collision is a collision in which some of the kinetic energy changes into a different form of energy.
Give a situation that involves three different types of energy
Many possibilities
What is the LHC (Large Hadron Collider) used for?
Protons are chucked at each other at extremely high energies. The purpose for the LHC is to discover more about atoms and how many other little tiny particle things- like hadrons - are in atoms.
Give an example of an elastic collision.
Many possibilities.
Describe fusion and fission
Fusion- nuclear reaction in which two hydrogen nuclei fuse together to form a helium nucleus
Fission- nuclear reaction in which a large nucleus splits to form two or three smaller nuclei
Describe work
Work is a mechanical process whereby energy is transferred from one object to another by a force
Describe elastic collisions.
An Elastic collision is a collision in which kinetic energy is conserved.
What is energy?
Two possibilities:
1. The glue of the world
2. There isn't a definition of energy that gets right to the point, so if you say IDK, you get it right!
Describe heat
Heat is energy in transit from a warm body or region to a cooler one (by means of infrared radiation, thermal conduction, or convection)
What is the equation for momentum?
Momentum is mass times velocity.
