1.  Simple harmonic motion is a repetitive movement through a center position so that the displacement on each side is equal. Because the displacement is the same, the force of each side is equal and the time of the vibrations is also the same.

2.  Hooke’s Law states that the displacement or size of the deformation is directly proportional to the deforming force. The two variables are force (F) and X scales.

3. When a pendulum swings back and forth, there is a constant exchange of potential and kinetic energy. When the swing reaches its maximum displacement, there is a maximum amount of potential energy. At the peak, there is no speed, so the kinetic energy is zero. As the pendulum goes down, the kinetic energy goes up.

4. A wave is a progressive disturbance propagated from point to point in a medium or space without progress or advance by the points themselves. An amplitude is the height of a wave. The period is the distance from one trough or crest to another. Frequency is the amount of wave crests or troughs that passes through a point in a given amount of time.

5. T=2π√(L/ag) is the equation for a simple pendulum (T → period(s) L → length of pendulum (m) ag  → gravity (m/s2))  and T=2π√(m/k) is the equation for a mass-spring system (T → period(s) m →mass (g) k → spring constant (N/m)).

6. A median in terms of waves is a substance that makes possible the transfer of energy from one location to another.

7. Mechanical waves refer to the oscillation of matter within a medium. This can refer to things such as sound which require air to work properly.

8. A transverse wave is similar in form to a sine or cosine wave meaning that it oscillates at a right angle. It has a given wavelength and amplitude. Light typically comes in the form of transverse waves.

9. Longitudinal waves are more interesting and take on a circular/polar form in which they circle around like a spiral. Typical music is made of longitudinal waves and different oscillations, their sound is altered through fade-off in amplitude, difference in wave-length, etc.

10.  A crest is a high point within the wave, while the trough acts as the low point of said wave. Wavelength refers to the distance between the repetition within a wave (this can be measured from crest to crest or trough to trough).

11.  Constructive interference occurs when two waves mix together and increase the amplitude of wave. Thus, the crests and troughs are respectively higher and lower (imagine a song boosted way above the volume it was recorded at). Destructive interference occurs when waves cancel each other leading crests and troughs to move closer towards the center (imagine a song in which the volume is lowered to a point where the song is almost inaudible).

(1)What is simple harmonic motion?

Simple harmonic motion is oscillatory motion under a retarding force proportional to the amount of displacement from an equilibrium position.

(2) What is Hooke's Law and define variables

Force in N (F) = -k (Spring constant in N/m) * x(deformation in m)

(3) Explain how gravitational potential energy and KE changes during pendulum movement

At the highest point of the swing, the object has no kinetic energy and the maximum gravitational potential energy. At the minimum height, the object has the maximum kinetic energy and minimum gravitational potential energy. From left to right, the object loses potential and gains kinetic energy until it reaches the minimum height. From the minimum height to the right, the object loses kinetic energy and gains potential energy.

(4) Define the following Wave, Amplitude, period, frequency

A wave is any regularly recurring event that is a disturbance through a medium. Amplitude is the height of the wave, frequency is the rate at ehich the vibration occurs, and period is the time needed for one complete cycle of vibration to pass a given point.

(5) What is the formula and variables to find period in simple harmonic motion of a pendulum and the formula for a mass-spring system.

For the period of a pendulum, where T is the period, L is the effective length of the pendulum, and g is the acceleration due to gravity.

T=m12u2dm

This is the formula for a mass-spring system.

(6) What is a medium in relation to waves

A medium is what the waves travel through.

(7) What is a mechanical waves

A mechanical wave is the transfer of energy through a medium, otherwise defined as the oscillation of matter.

(8) What is a transverse wave (what does it look like and cite examples)

A transverse wave is a wave vibrating in a direction that is at a right angle relative to its point of origin.

(9) What is a longitudinal wave (what does it look like and cite examples)

In a longitudinal wave, the displacement of the medium is parallel to the direction of propagation. An example would be seismic P-waves created by earthquakes and explosions.

(10) Define a crest, trough and wavelength

Crest is the highest point on a wave; it is the point on a wave with the maximum value of upward displacement in one cycle.

Trough is the lowest point on a wave; it is the point on a wave with the minimum value of downward displacement in one cycle.

Wavelength is the distance between corresponding points of two consecutive waves.

(11) What is the difference between constructive and destructive interference.

Constructive interference is when the crests of two waves line up together (in this case the waves reinforce each other and the combination result is a single amplitude equal to the sum of their individual amplitudes), while destructive interference is when the crest of one wave meets the trough of another and the combination result is a lower total amplitude.

8. A transverse wave is a wave that vibrates at right angles (90 degrees) towards its propagation. It looks like a series of crests with troughs in between each crest. An example of this is the vibration in a string.
9. A longitudinal wave is a wave that vibrates towards its propagation. It looks like a spring like the ones in pens. An example is a sound wave.
10. A crest is the point on a wave with the highest point and the trough is the lowest point and a wavelength is the distance between 2 crests.
11. The difference between constructive and destructive interference is that a constructive intereference has a higher amplitude whereas a constructive has a lower amplitude. In a constructive 2 waves meet up to line up their crests while in a destructive the waves' crests meet the other waves' troughs.
