17 Different Science Formulae for Junior High Students

By Editorial StaffEducation, How-to & Finance

Introduction

Here we present to you 17 different science formulae to boost your studies as a junior high school student.

These formulae are selected from the fields of the science which deals with calculations. They are to guide students in their learners and to also a one-stop toolbox to perform all science activities involving calculations.

Though the science formulae listed in here are ideal for junior high students but could as be used in all levels of education.

Science topics included for these 17 different science formulae are

Topics

  • Measurement
  • Energy and energy conservations
  • Light energy
  • Forces and pressure
  • Electrical energy

Below are also the science phenomena the 17 different science formulae are built on;

Science Phenomena

  • Potential difference
  • Resistance
  • Current
  • Displacement
  • Refractive index
  • Magnification
  • Kinetic energy
  • Potential energy
  • Density
  • Weight
  • Volume
  • Mass
  • Pressure
  • Force
  • Workdone

In cases where there are alternate formulae to the ones uploaded here, we will accordingly add them.

You can apply these formulae when you are studying any of the selected topics listed above.

Science Formulae

Find the lists of 17 science formulae in the lines below;

  • Potential Difference

V= Resistance X Current

V=RI

Where V is for potential difference, R for resistance and I for current

  • Resistance = Potential difference/Current

R=V/I

  • Current = Potential difference/Resistance

I=V/R

  • Displacement

=Real depth – Apparent depth

  • Refractive index

Real depth/Apparent depth

n=real depth/apparent depth

  • Magnification

=image height (h1)/object height (h0)

m=h1/h0

Where m = magnification, h1 = image height and ho = object height

  • Kinetic energy

K= ½ mv2 , where m= mass of an object, v= velocity

  • Potential energy = mass X gravity X height

                                  mgh

Alternatively, potential energy=weight X height

  • Density = mass/volume
  • Weight = mass X gravity

                  m X a

                   ma

  • Volume of cube = l3
  • Volume of a cuboid = length X width X height

                                        LWH

Alternatively, you can obtain volume using the density and mass of a body, let see how it goes.

Volume = Mass/Density

  • Mass = Force/gravity

m=f/a; where f = force and a = gravity

  • Pressure = force/area

    P=F/A; where P=pressure, F= force and A = area

  • Force = mass X acceleration

F=ma

  • Work done = force X distance

Conclusion

These 17 science formulae can be used while studying in classrooms or at home.

I recommend that those preparing for their BECE/WASSCE exams should make these their close companion.

Instructors can also make a copy of these 17 science formulae, paste them in classrooms or better still include them in Teaching and learning resource
