Einstein Mass Energy Calculator
Einstein Mass-Energy Calculator is a tool used to calculate the energy (E) equivalent of a mass (m) based on Albert Einstein's famous equation: E=mc2.
What is Energy?
It is an important role of the body which transforms the state of the body from one state to another state or transfers from one object to another object.
Formula of Einstein's Energy Equation
E = mc2
Here,
- m = mass of an object
- c = speed of light in vacuum
It is used to measure energy in the system of the metric that is used in European countries and is defined as the amount of energy converted when a force of one newton is applied at a distance of one meter.
It plays an exclusive role in understanding the behavior and motion of an object in the physical world.
Examples
Example 1:
Calculate the energy if mass = 125 and speed of light in vacuum = 5.
Solution
Step 1:
Write the data carefully.
m = 125, c = 5, F =?
Formula:
E = mc2
Step 2:
Put the all values in the above formula and simplify carefully.
m = 125, c = 5,
E = mc2
E = 125 × (5)2
E = 125 × 25
E = 3125 J
Example 2:
Determine the speed of light in a vacuum if mass = 5, and Energy = 150
Solution
Step 1:
Write the data carefully.
m = 5, E = 150, c =?
Formula:
c = √E/m
Step 2:
Put the all values in the above formula and simplify carefully.
m = 5, E = 150
c = √E/m
c = √150/5
c = √30
c = 5.48 m/s
Example 3:
Determine the mass if the speed of light = 5 and energy = 150
Solution
Step 1:
Write the data carefully.
c = 5, E = 150, m =?
Formula:
m = E/c2
Step 2:
Put the all values in the above formula and simplify carefully.
c = 5, E = 150
m = E/c2
m = 150/(5)2
m = 150/25
m = 6 kg
