The Total Mechanical Energy Calculator is an online tool designed to compute the mechanical energy of an object in motion. It evaluates the total energy contained within a system by summing up its kinetic and potential energies. This calculation is crucial for predicting the movement of objects under various forces and for making accurate physical assessments in real-world applications.
Formula of Total Mechanical Energy Calculator
Total mechanical energy E of a system is calculated using the formula:
Where:
- K is the kinetic energy, given by K = 1/2 * m * v^2 (where m is the mass of the object and v is its velocity).
- U is the potential energy, which depends on the type of forces acting on the object (e.g., gravitational potential energy, elastic potential energy, etc.).
Table of General Terms
The following table includes commonly searched terms related to mechanical energy, providing a handy reference for users to understand and utilize the calculator more effectively:
| Term | Definition |
|---|---|
| Mechanical Energy | The sum of kinetic and potential energies in a system. |
| Kinetic Energy (K) | Energy that an object possesses due to its motion. |
| Potential Energy (U) | Energy stored due to an object’s position or state. |
Example of Total Mechanical Energy Calculator
Consider a projectile launched into the air with a mass of 5 kg and a velocity of 20 m/s at its highest point. The kinetic energy at this point would be calculated as follows:
K = 1/2 * 5 * 20^2 = 1000 joules
If the projectile reaches a height of 10 meters, assuming the acceleration due to gravity g = 9.8 m/s^2, the potential energy is:
U = 5 * 9.8 * 10 = 490 joules
Thus, the total mechanical energy is:
E = 1000 + 490 = 1490 joules
