⁣The central nervous system (CNS) is made up of the brain and spinal cord. It is one of 2 parts of the nervous system. The other part is the peripheral nervous system, which consists of nerves that connect the brain and spinal cord to the rest of the body. The central nervous system is the body's processing centre.

Lyrics

A car heading for the borderline.
distance travelled = speed × time
s = v t


You want to measure the acceleration?
acceleration=(change in velocity)/(time taken)
a=(Δ v)/t

Try to build the momentum properly.
momentum = m**** × velocity
p = m v

Turn on the speaker. It’s a song from Eminem.
wave speed = frequency × wavelength
v = f λ

Ain’t nobody as ‘phat’ as me.
weight = m**** × gravitational field strength g
W = m g

I use the force in this rap equation.
resultant force = m**** × acceleration
F = m a

pressure=(force normal to a surface)/(area of that surface)
p=F/A

There’s too much density in this whole tune.
density=m****/volume
ρ=m/V

23 Physics Equations.
We’ll take it one by one so have patience.
23 Physics Equations.
We’ll take it one by one so have patience.


A powerful quarterback runs on the touchline.
power=(work done)/time
P=W/t

Or

power=(energy transferred)/time
P=E/t

If we’re talking about transfers, then check this rhyme.
What football transfer would you like to happen, if you had infinite money to buy?
energy transferred = power × time
E = P t

Another way to get energy transferred, this physics equation I’m spitting.
energy transferred = charge flow × potential difference
E = Q V

My bars. I don’t charge at this current time.
charge flow = current × time
Q = I t

If you want to measure the potential difference.
potential difference = current × resistance
V = I R

Two more power equations all of a sudden.
power = potential difference × current
P = V I

Another equation for power. Sit back and listen.
power = (current)2 × resistance
P = I2 R

Chorus

In a factory, putting of a piston.
work done = force × distance along the line of action of the force
W = F s

You want to know the force applied to a spring?
force applied to a spring = spring constant × extension
F = k e

moment of a force = force × distance normal to direction of force
M = F d
The symbol is M = Fd but you knew that of course.


Efficiency is a mission to me but kinetic energy let’s do first.
kinetic energy = 0.5 × m**** × (speed)2
E_k=1/2 m


efficiecy=(useful output energy transfer)/(total input energy transfer)

Or

efficiecy=(total power output)/(total power input)


That’s 22 equations from your physics book.
One more to do before I spit the hook.

gravitational potential energy = m**** × gravitational field strength (g) × height
Ep = m g h
That’s 23 equations done. Good night.

What is Linear Motion?

Now, what is motion in a straight line? Objects move in motion, right? Those objects may move in 1 dimension, 2 dimensions or 3 dimensions. Today, we are going to discuss the motion of an object in 1 dimension. And that is the motion in a straight line. Motion in a straight line can also be called Linear Motion.

In Linear Motion, we will be talking about the position, displacement, velocity, and acceleration of an object.
Alright! Let’s start with Position.

The position of an object along a straight line can be uniquely identified by its distance from the origin. What does that mean? It means that the object only moves in one coordinate in the Cartesian plane which may go to the right or to the left of the 0.

The position of an object is relative to the reference frames. But what is a reference frame? A reference frame is an arbitrary set of axes from which the position and motion of an object are described. It means that it is where we base the motion of an object.

Take for example a rocket to be launched into outer space. Since the final destination of the rocket is in outer space, we can use the Earth as our reference frame. And from there, we can now calculate the position of the rocket with respect to Earth.

But not all reference frames are stationary in a linear motion. Sometimes, there are also moving reference frames that we can use in getting the position of an object in motion.

Enjoy this video about motion along a straight or in its other name which is the linear motion.

020 - Ionic Bonding

In this video Paul Andersen explains how ionic solids form when cations and anions are attracted. When atoms lose or gain electrons they form ions. The strength of the attraction between ions is based on the amount of charge and the distance between the ions.

⁣There are different tests which can be used to detect carbohydrates, proteins and lipids.
They involve adding a reagent to a food sample which changes colour depending on what biological molecules are present.

Mr. Andersen shows you how to draw Lewis Dot Diagrams for atoms and simple molecules.

What is velocity? How is the velocity & acceleration related?
Watch this video to understand the concept of Velocity in physics.
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt. Speed (or rate, r) is a scalar quantity that measures the distance traveled (d) over the change in time (Δt), represented by the equation r = d/Δt.
