Wieght VS Mass:
weight is the mass in a given place and varies even from place to place on earth, mass is a constant, found by comparing the mass to that of a known object using a balence, the mass on the moon is the same as on earth or anywhere else.
Dencity VS Volume:
dencity is mass to volume and volume is just how much space something takes up.
Velocity VS Speed:
velocity is speed, but also includes direction, when you swing something around, the speed may stay the same, but the velocity is constantly changing because the dirrection is changing.

a) Velocity is a vector (one that has value and direction) quantity, Speed is a scalar (no direction but value only) quantity.
b) Weight is a force (exerted by a mass as a result of gravity) and mass is the amount of matter in an object.
c) Density is mass/unit volume and volume is the 3D space occupied by an object

A) Velocity includes the direction you're going
B) Weight is subject to gravity, mass is the amount of matter in an object/thing
C) Density is how packed together matter is in something, and requires volume to calculate it. Volume is how much of somethingthere is.

Speed is rate of change of displacement - It is scalar
Veolcity is rate of change of displacement with direction - It is a vector
Weight - Mass in a gravity (In our world weight = mass * 9.81)
Mass - Density * volume - it is independent of the place of measurement
Density - Mass per unit volume
Volume - Space occupied by a given mass

velocity is a vector quantity while speed is scaler.velocity is displacement per unit time and speed is distance per unit time.weight of any substance equals to mass into accerelation due to gravity while mass is quantity of substance occupied by substance.density is mass per unit volume while volume is how much matter a container or a substance can intake

speed a scalar is rate of change of distance
velocity a vector is rate of change of displacement
mass is the amount of matter contained in a body
weight is the force with which th gravity pulls it=m*g
density is the mass per unit volume volume is the capacity or the space occupied

a. velocity factors in direction along with speed
b. weight is relative to other objects, mass is constant. For example if you go to the moon, your weight would be approximately 1/6 of what it was measured on earth. Mass is the "amount" of matter. Your mass would be the same on Earth, the moon, Jupiter, or anywhere.
c. density is mass divided by volume.
It's been awhile since I took physics, so if I'm wrong, please be nice, people.

A ton of little ones those days are trying not hardship-free to look "emo" by using fact they think of it looks cool. If somebody is making an attempt to look emo or regardless of, they only are available in the process as immature teenagers searching for interest. Emo is generally in basic terms a outfits style regarding darkish hues and piercings. they don't have suicidal ideas any extra than human beings. Emos are generally youthful little ones wanting to get interest. actual goths somewhat follow the gothic faith and placed on all black, with black hair. in no way heard of juggalos! Scene is generally in simple terms prevalent for the extensive hairstyles. maximum punks like shade. you're superb suited with regard to the mohawks and spikes. I somewhat have had many acquaintances pass in the process the "emo wannabe" section, and so did I. And now that we are older we understand how dumb and immature we've been. i've got discovered my lesson the not hardship-free way! desire I helped. Have a great week

difference b/w speed and velocity
speed- 1) the distance covered per unit time.
2 ) it has only magnitude(value) no direction
3 )it is expressed as "x" km/hr
4 ) since it have no specified direction so it is a scalar quantity.
velocity- 1) it is displacement per unit time
2) it has magnitude as well as direction
3)it is expressed as "x" km/hr towards "y" direction , the may be east or west and so on .
4)since it has specified direction so it is a vector quantity.
