-- A wave travels from place to place. 
   A pendulum just sits there.

-- A wave carries energy.  A pendulum has energy,
   but doesn't take it anywhere.

-- A wave is a traveling pattern of maximums and minimums
   that all exist at the same time but in different places.
   A pendulum is a stationary pattern of maximums and minimums
   that all exist in the same place but at different times.
   (I made this one up just now;  I really like it.)   

What makes you think that all oscillators must be pendulums,
or must be waves, or must be both, anyway ?

A guitar string is an oscillator that has waves on it,
but no pendulum anywhere nearby.

A car horn is an oscillator that sends waves out
but there's no pendulum anywhere nearby.

An analog wrist watch has an oscillator in it, which is
actually a torsion pendulum, but there are no waves
anywhere nearby.

Going just one step further with the logic of your question ...
If the logic held water, then we would have to ask:
A horse and a dog are both animals. 
So why isn't a horse a dog ?

The formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle involve the use of which fun
gizmo_the_mogwai [7]

The formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle involve the use of tangent, cosine and sine.

<h3>What is vertical motion of a projecile?</h3>

The vertical motion of a projectile is affected by gravity and the velocity of vertical motion given by the following formula;

Vy = Vsinθ

<h3>What is horizontal motion of a projecile?</h3>

The horizontal velocity of a projectile is given by the following formula;

Vx = Vcosθ

<h3>Direction of the motion</h3>

The direction of the motion is calculated as follows;

tanθ  = Vy/Vx

Thus, the formulas used to analyze the horizontal and vertical motion of projectiles launched at an angle involve the use of tangent, cosine and sine.

Discuss why the article says the fact that we’re in our universe complicates our understanding of the expansion of the universe.
MArishka [77]
<span>Because of our perception of the universe from inside the universe, we are unable to see how and towards what the universe is expanding. Also, our understanding of it is further complicated because we are moving as part of the expansion, thus distorting our perception of it.</span>

How much work would be needed to raise the payload from the surface of the moon (i.e., x = r) to an altitude of 5r miles above t
Cloud [144]

Let the data is as following

mass of payload = "m"

mass of Moon = "M"

now we know that we place the payload from the position on the surface of moon to the position of 5r from the surface

So in this case we can say that change in the gravitational potential energy is equal to the work done to move the mass from one position to other

so it is given by

W = U_f - U_i

we know that

U_f = -\frac{GMm}{6r}

U_i = -\frac{GMm}{r}

now from above formula

W = -\frac{GMm}{6r} + \frac{GMm}{r}

W = \frac{5GMm}{6r}

so above is the work done to move the mass from surface to given altitude
