## How to Calculate and Solve for Gravitational Potential | The Calculator Encyclopedia

The image above represents the Gravitational potential.

To compute the gravitational potential of a field, two essential parameters are needed which are mass (m) and radius (r).

The formula for calculating the gravitational potential;

V = (Gm) / r

Where;
V = Gravitational potential
m = Mass

Let’s solve an example;
Find the gravitational potential of a field when the mass is 14 cm with a radius of 9 cm.

This implies that;
m = Mass = 14 cm
r = Radius = 9 cm

V = (Gm) / r
V = (6.67 x 10-11 x 14) / 9
V = 1.0375e-10 / 9
V = 1.0375e-10

Therefore, the gravitational potential is 1.0375e-10 Volts (V).

## How to Calculate and Solve for Gravitational Force | The Calculator Encyclopedia

The image above represents the gravitational force.

To compute the gravitational force of a field, three parameters are needed and this parameters are mass (m1), mass (m2) and radius between the masses (R).

The formula for calculating the gravitational force:

F = Gm1m2 /

Where;
F = Gravitational force
m1 = Mass 1
m2 = Mass 2
r = Radius between the masses

Let’s solve an example;
Find the gravitational force of a field when the mass 1 is 8 cm, mass 2 is 10 cm and the radius between masses is 14 cm.

This implies that;
m1 = Mass 1 = 8 cm
m2 = Mass 2 = 10 cm
r = Radius between the masses = 14 cm

F = Gm1m2 /
F = (6.67 x 10-11 x 8 x 10) / 196
F = 5.336e-9 / 196
F = 2.722e-11

Therefore, the gravitational force is 2.722e-11 Newton (N).

## The Calculator Encyclopedia Calculates and Solves the Wavelength for a Wave – Particle Behaviour

According to Wikipedia,

Wave–particle duality is the concept in quantum mechanics that every particle or quantum entity may be partly described in terms not only of particles, but also of waves.

In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave’s shape repeats.

Nickzom Calculator requires two parameters to compute the wavelength of a wave or particle. These parameters are:

• Mass
• Velocity

The formula for computing the wavelength is:

λ = h / mv

Where:
λ = Wavelength
h = Planck’s Constant (6.63 x 10-34 js)
m = Mass
v = Velocity

Let’s solve an example, find the wavelength of a wave – particle with a mass of 300 Kg and a velocity of 3 x 1010 m/s.

From the example, we can see that:
m = 300
v = 3 x 1010

λ = 6.63 x 10-34 / 300 (3 x 1010)
λ = 6.63 x 10-34 / 9 x 1012
λ = 7.37 x 10-47

Therefore, the wavelength of the wave – particle (λ) is 7.37 x 10-47.
