Waves
This law applies to waves reflecting off surfaces.
What is the Law of Reflection?
**Daily Double: State the Law of Reflection.
A push or a pull.
What is force?
This is an accumulation of charge.
What is static electricity?
**Daily Double: What is static discharge?
This is the formula to solve for Voltage.
What is V = current x resistance?
The bending of a wave as it passes from one medium into another.
What is refraction?
A property possessed by all matter. Because of this property, matter resists change to its state of motion.
What is inertia?
The flowing of charges (negative electrons).
What is current?
The formula for velocity when given the acceleration.
What is acceleration x time?
This is the main difference between mechanical and light waves.
What is mechanical waves require a medium of some kind to propagate while light waves do not?
In the absence of a force, an object will remain in its present state of motion, either at rest, or moving at a constant speed in the same direction.
What is Newton's 1st Law of Motion?
**Daily Double: Name Newton's 2nd and 3rd Laws of Motion.
a current flowing in a wire creates a magnetic field around the wire and the strength of the magnetic field is directly proportional to the current.
What is Ampere's Law?
How much force is required to accelerate a large truck with a mass of 4,500 kg at a rate of 2.5 m/s2
What is 11,250 N?
This is the definition of diffraction.
What is when a wave encounters an obstacle or corner and bends around it and spreads out?
Energy can be neither created nor destroyed, only changed in form.
What is the Law of Conservation of Energy?
This is when a changing magnetic field is passing through a coil of wire a current will be induced in the wire.
What is Faraday's Law of Induction?
**Daily Double: Name the three ways static electricity forms.
The particles in a certain fluid move 5.5 cm in 3.5 μs. Determine the velocity of these particles, and state your result in m/s.
What is 15,714 m/s?
A disturbance in space and time that carries energy from one place to another.
What is a wave?
A mathematical concept used to describe the strength, range, and direction associated with the force one object can exert on another object without touching.
What is a field?
When all resistors are in the same loop of wire, one after the other.
What is a series circuit?
** Daily Double: Explain what a parallel circuit is.
A 12-volt battery is keeping the overhead light on in a car, even though the car's engine is off. If the resistance of the overhead light bulb is 125 ohms, determine the current flowing in the circuit.
What is 0.096 A?
