Mathematics in Science

Having an excellent talent in math is very important. So today, I will describe some formulas necessary in science.
 


Density =  Mass / Volume  

Density- the relationship between mass and density, how tightly packed the particles are(mass unit/volume unit)
Mass- Amount of matter in an object (in kg or g)
Volume - how much space an object takes up (cm3, mL, L) 
Ex. 6 kg / 2mL = 3 kg/mL 

Speed = Distance / Time 

Speed- how much distance can an object cover in an amount of time(distance unit/ time unit) 
Distance- how far something travels (km, mi)
Time- how long it takes to complete a task (hrs,min)
Ex. 120mi./10hrs = 1.2 mi/hr 

Net Force = f1 - f2

Net Force- the amount of force that causes an object to move in the direction of the more powerful force(Newtons(N), to the direction of the stronger force)
f1- the larger force(Newtons(N), to the direction of …)
f2- the weaker force(Newtons(N), to the direction of …) 
Ex. 160N to the right - 130N to the left = 30N  to the right  

Work = Force ✕ Distance 

Work- applying a force to move an object(joules(J) 
Force- a push or a pull(Newtons(N))
Distance- how far something travels(m) 
Ex. 30N ✕  2m = 60J 

These aren’t all the formulas in science, there are still a ton of them!
