Wave Goodbye
A disturbance that moves through matter or space.
What is a wave?
Tools that make work easier
What is a simple machine?
A very large star of high luminosity and low surface temperature
What is a Red Giant?
A push or pull on an object that may or may not cause motion, has a size and direction
What is force?
The ability the do work
What is energy?
The number of wavelengths that pass by a point each second.
What is frequency?
Force created when two objects rub against each other
What is friction?
What is a white dwarf?
the rate at which velocity changes over time
What is acceleration?
the energy an object has because of its position
What is potential energy?
A wave that can travel through matter or empty space.
What is an electromagnetic wave?
A wheel that has a rope wrapped around it. Used to lift heavy objects by changing the direction or amount of the force.
What is a pulley?
An extremely dense, compact star composed primarily of neutrons, especially the collapsed core of a supernova.
What is a neutron star?
an object at rest will stay at rest; an object in motion will stay in motion unless acted on by an outside force
What is Newton's 1st Law?
The energy of motion
What is kinetic energy?
Causes particles in matter to move back and forth at right angles to the direction in which the wave travels.
What is a transverse wave?
A stiff bar that moves about a fixed point(fulcrum). It is a simple machine that is used to push, pull, or lift things.
What is a lever?
the first stage in every stars life
What is a nebula?
The rate at which an object moves
What is speed?
A machine that converts chemical energy in fossil fuels into electric energy
What is an electric generator?
The distance between 1 point on a wave and nearest points moving in the same direction in which the wave travels.
What is wavelength?
The transfer of energy that occurs when a force makes an object move. Measured in Joules.
What is work?
the fifth stage in a high mass stars life, after the red super giant expands it collapsed in itself so rapidly that when it is done it explodes outwards.
What is a supernova?
the force of attraction between all masses in the universe
What is gravity?
the process in which the nucleus of an atom is split into 2 smaller nuclei
What is nuclear fission?
