WAVES
What are "waves"
a disturbance that carries energy from one location to another location.
Whats Newtons 1st Law
An object at rest remains at rest unless acted on by an unbalanced force.
Define kinetic energy
is the energy of motion.
Whats an Electric Charge
Objects become positively charged when they lose electrons and negatively charged when they gain electrons; objects with like charges repel and objects with opposite charges attract
What is Energy?
Energy means the ability to do work.
What are the types of waves
-Mechanical waves
-Transverse waves
-Longitudinal waves
Whats Newtons 2nd law
That the net force is equal to the acceleration times the mass of the object (F=ma).
What is a soild
A solid is matter with a definite shape and definite volume.
What are Electric Circuits
Circuits control the movement of electric current by providing paths for electrons to follow.
what is Potential Energy
Potential energy is stored energy due to an object’s position energy ready to go.
How do Transverse waves move
in a direction perpendicular to the direction that the wave moves.
What's Newton's 3rd law
That for every action, there is an equal and opposite reaction.
Whats a liquid
A liquid is matter that has a definite volume but no definite shape.
What are connections in a Circuit
Electrons flow from negative to positive; therefore, a complete circuit must have wires that connect the negative pole of the energy source to the positive pole of the energy source.
What is Elastic Potential Energy
Elastic potential energy is the energy stored in elastic materials as a result of their stretching or compressing.
what are the types of a wave
crest, trough, amplitude, wavelength, and wave height.
What's the equation for newtons 1st law
p = mv (momentum = mass * velocity) F = ma (force = mass * acceleration)
What's a gas
Gas is a matter that does not have a definite shape or volume.
What is Voltage
Voltage is the potential difference between two points in a circuit.
What is Gravitational Potential Energy
Potential energy that is related to an object's height above the ground is known as gravitational potential energy.
what waves have the longest wavelength, and the shortest
Radio waves have the longest, and Radio waves have the longest
What Happens if you push someone
Newton's third law of motion dictates that they will push back on you with an equal and opposite force when you push someone.
What are Particles in Gases
Gas particles move freely in all directions, except during occasional collisions.
What is Resistance
Resistance is how difficult it is for electrons to flow through a material (friction).
Example of Gravitational PE
The water sitting behind the dam has gravitational potential energy.
