What does the capacitor do?
a capacitor stores electrical energy
What do transverse and longitudinal waves have in common?
they tranport energy
In which phase(s) do molecules move freely?
gas
Which energy sources (input) can cause the turbine (wooden wheel) to spin and generate electrical energy?
the energy sources that can cause the turbane to spin and generate electrical energy are water and wind
what best supports acceleration
a ball roling down a hill
What makes the switch handy?
it can open or close a circuit controlling the flow of current
The waves speed depends ONLY on
The medium its traveling through
In which phase(s) are molecules held together?
solid
Explain why the cyclist must be fed in order to continue to pedal?
food provides chemical energy which is converted to mechanical energy to power the muscles being used
the force of gravity of a person or object at the surface of a planet is known as?
weight
whats electricity
the presence and/or flow of electric charges
The energy of a wave is related to the ______ of a wave.
Amplitude
In which phase(s) is water held in a defined shape?
solid
Explain why the cyclist must be fed in order to continue to pedal?
energy cannot be created or destroyed only transformed from one to another
calculate the acceleration of a 7 kg mass if a force of 68.6 N acts on it
9.8m/s^2
what are circuits for?
control the movement of electric current by providing paths for electrons to follow.
What is frequency?
The amount of cycles that pass through in a given second
In which phase(s) does the water take the shape of the container?
When there is no friction, what is the only factor that affects the final speed of a roller coaster?
the mass is the only factor that determines the final speed
Amy runs 2 miles south then turns back and runs 4 miles north. what is her displacement vector?
4.47 north
How are series and parallel circuits similar and different in how they transfer energy?
In series circuits, components are connected in a single loop, meaning the same current flows through each component. Voltage is distributed across the components. In parallel circuits, components are connected across multiple paths, allowing current to split and flow simultaneously through each branch
What happens to the amount of energy that is being carried by a wave as it moves out from its source?
It gets weaker.
At what temperature will water change from a liquid to a gas (boil)?
100
How are potential energy, kinetic energy, and total energy related?
the total energy of an object is the sum of the potential kinetic energy
forces that are equal in size but opposite in direction are ?
balanced forces
