Calculations in kinetic and potential energy
To calculate kinetic energy (KE), you need the mass of the object and its velocity. The formula for kinetic energy is:
KE = 0.5 * m * v^2
Where:
- KE is the kinetic energy in joules (J)
- m is the mass of the object in kilograms (kg)
- v is the velocity of the object in meters per second (m/s)
To calculate potential energy (PE), you need the mass of the object, the acceleration due to gravity, and the height of the object. The formula for potential energy is:
PE = m * g * h
Where:
- PE is the potential energy in joules (J)
- m is the mass of the object in kilograms (kg)
- g is the acceleration due to gravity, which is approximately 9.8 meters per second squared (m/s^2)
- h is the height of the object in meters (m)
It's important to note that in calculations involving kinetic and potential energy, mass is typically measured in kilograms, velocity in meters per second, and height in meters, to ensure consistent units throughout the calculations.

Kinetic Energy:
The formula to calculate kinetic energy is given by:
KE = 0.5 * m * v^2
where KE represents the kinetic energy, m is the mass of the object, and v is the velocity of the object.
Potential Energy:
The formula to calculate potential energy depends on the type of potential energy you are referring to:
1. Gravitational Potential Energy:
The formula to calculate gravitational potential energy is given by:
GPE = m * g * h
where GPE represents gravitational potential energy, m is the mass of the object, g is the acceleration due to gravity, and h is the height of the object above a reference point.
The value of g is approximately 9.8 m/s^2 on Earth.
2. Elastic Potential Energy:
The formula to calculate elastic potential energy is given by:
EPE = 0.5 * k * x^2
where EPE represents elastic potential energy, k is the spring constant of the object, and x is the displacement from the equilibrium position of the object.
