Which of Newtons Laws states that for every action there is an equal and opposite reaction?
Newtons 3rd Law
what is a wave?
a disturbance that carries energy from one location to another location.
what is electricity?
the presence
and/or flow of electric
charges
what does iso mean?
It means the same.
what does energy mean?
it means the ability to work
which of Newton's Laws explain inertia?
Newtons 1st Law
What is a medium?
is a substance or material that carries the wave.
what do circuits control?
control the movement of electric current by providing paths for electrons to follow.
what breaks down compounds?
chemicals
where is potential energy stored?
due to an object’s
position--energy ready to
go.
who discovered Newtons Laws?
Issac Newtons
what is a transverse wave?
medium moves in a direction perpendicular to the direction that the wave moves.
what do conductors have in common?
free electrons that allow electric currents
What does increased temperature mean when talking about kinetic energy?
Increased temperature means greater average
kinetic energy, so most substances expand
when heated.
what is kinetic energy?
is the energy of motion
According to Newton's first law of motion,what will a moving object that is not acted on by an unbalanced force do?
It will stay the same speed & direction
what is it called when a wave is bending
around an object or barrier.
Diffraction
What do the insulators have in common?
do not have free electrons prevents are flow
How many states of matter are there?
There are four familiar states of matter—
solid, liquid, gas , and plasma .
what is the formula for Kinetic Energy?
KE= ½ mv² (1/2 x mass x velocity²)
What does Newton's second law of motion state about an objects acceleration?
its proportional to net force acting on an object
What does it mean when a wave appears black and white?
When something appears black it is absorbing all of the light.If an object appears white none of the light is absorbed.
what happens when voltage increases
is the potential difference between two
points in a circuit.
what is all matter made up of?
All matter is made up of tiny particles, such as
atoms, molecules, or ions.
what is the formula for potential energy?
PE=mgh (mass x g=9.8m/s² x height)
