How to Calculate Different Types of Energy?

What are the different types of energy?

Choose the correct answer: potential, kinetic, or elastic energy.

Answer:

After the mass is pulled, you have all three types of energy: potential, kinetic, and elastic.

When dealing with calculating energy, it is essential to understand the different types of energy involved. Potential energy is the energy an object has due to its position, while kinetic energy is the energy an object possesses due to its motion. Elastic energy, on the other hand, is the energy stored in an elastic object due to stretching or compression.

In this scenario, the motionless mass, when pulled 5 cm downward, exhibits potential energy as it is one meter above the classroom floor, kinetic energy due to its motion, and elastic energy due to the extension of the spring.

To calculate these energies, specific equations are used. For elastic energy, the formula is Eelas = 0.5 * k * x2, where k is the spring constant and x is the distance. Potential energy can be calculated using Epot = m * g * h, with m as the mass, g as gravity (9.81 m/s2), and h as the elevation. Kinetic energy is determined by Ek = 0.5 * m * v2, where m is the mass and v is the velocity.

Overall, understanding and calculating these different types of energy can provide valuable insights into the dynamics of a system and help in solving complex problems related to energy transformations.
