Circuits
The flow of charged particles is an?
electric current
What is a wave?
a disturbance that carries energy from one location to another.
What are the 3 common states of matter?
Solid, liquid, gas
What is energy?
Energy is the ability to do work
What is inertia?
the tendency of an object to resist changes in its state of motion
What do circuits do?
Circuits control the movement of electric current by providing paths for electrons to follow.
What must all waves have to travel?
ENERGY not matter
How do the particles in each state of matter move?
In solids, particles are tightly packed and vibrate in fixed positions. In liquids, particles are less tightly packed and can move around each other, allowing them to flow. In gases, particles are far apart and move freely and rapidly in all directions, filling any available space
Name different forms of energy
heat, light, electricty, kinetic
What is the relationship between force, mass, and acceleration?
which states that force is equal to mass times acceleration
What 3 parts does a circuit need?
All circuits need three basic parts: an energy source, wires, and the object that is going to change the electrical energy into another form of energy (load).
Examples of transverse waves.
Ocean waves, Ripples on water surface, Vibrating guitar string, Electromagnetic waves
What happens when a liquid turns into a gas?
When a liquid turns into a gas, the process is called vaporization or evaporation
What is kinetic energy?
The energy of motion, also know as the energy of movement.
Why is it easier to push a light object than a heavy one?
It's easier to push a light object than a heavy one due to inertia and friction
What are some examples of load circuits?
light bulb, car, fan, toaster, speaker
Which wave requires no medium?
Electromagnetic waves
What is the difference between the melting point and the boiling point of water?
The main difference between the melting point and the boiling point of water is the state change they represent
What is energy efficiency?
The ratio of the energy output of a system to energy imput.
What is the action-reaction pair?
a pair of forces that occur when two objects interact
State and explain Kirchhoff's Law.
the total current entering a junction in a circuit equals the total current leaving that junction
If two waves of different frequencies are traveling in the same direction, what will happen to their interference pattern over time, and why?
The interference pattern will not be fixed in time. Instead, the pattern will vary periodically as the waves' crests and troughs align and de-align. This is because the different frequencies cause the waves to advance at different rates. Over time, the constructive and destructive interference zones will move along the path of the waves
How does pressure affect the state of matter?
Pressure affects the state of matter by altering the volume and intermolecular forces between particles, potentially forcing a phase transition
What is the difference between work and power?
Work is the energy transferred, while power is the rate at which energy is transferred.
What is the difference between unbalanced and balanced forces?
Objects acted upon by balanced forces stay at rest or move at a constant velocity. Unbalanced forces are forces that are not equal in magnitude and may or may not act in the same direction
