Chapter 3: Acceleration
What is 9.81 m/s^2
The value of acceleration on earth for an object in free fall
This law states that an object at rest remains at rest as long as no net force acts on it. An object moving with constant velocity continues to move with the same speed and in the same direction
what is Newton’s first law?
You arrive at this by taking the inverse of the period
How is frequency calculated?
The bending of light when it travels through a medium of different density
What is refraction?
These are the units of EMF (electromotive force)
what are volts?
what is acceleration
A measurement of when there is a change in speed, direction, or both.
This law states that force is equal to mass times acceleration (f = ma)
What is Newton’s second law?
The speed of a wave is affected by this.
What are the properties of the material or the medium through which it travels.
the separation of colors in refraction due to index of refraction being different for different wavelengths
what is dispersion?
A measure of the number of magnetic field lines that cross a given area.
What is magnetic flux?
This formula is a measurement of the change in Velocity over change in time
What is the formula for average acceleration?
This law states that for every action, there is an equal and opposite reaction
What is newton’s third law?
This happens when waves occupy the same space.
What is they combine and add together?
These quantities are needed to find the index of refraction
What is C (speed of light) and V (velocity)
This law is demonstrated by the equation EMF = -N change in flux/change in time (t)
what is faraday’s law?
The calculation of the area under the time-velocity curve gives you this
What is the distance traveled by an object?
This is the force exerted by a string, rope or wire that is pulled tight?
What is tension?
This type of wave causes interference.
What are standing waves?
The law indicated by the equation: n1 sin(theta1) = n2 sin(theta2)
What is Snell’s Law
This law states that an induced current always flows in a direction that opposes the change that cause it.
what is Lenz’s law?
A parabola with greater curvature indicates this.
What is greater magnitude?
f = kx
What is Hooke’s law?
A system that is driven at its natural frequency is said to have this quality.
What is a system that is in resonance?
The speed of light can change in different mediums under this circumstance
When the medium has different indexes of refraction.
When current is induced on a wire by a magnetic field that has a changing magnetic flux
what is electromagnetic induction?
