What is the formula for calculating kinetic energy?

The formula for calculating kinetic energy is represented as KE = 1/2 mv^2. This equation expresses that kinetic energy (KE) is directly proportional to the mass (m) of an object and the square of its velocity (v). The factor of 1/2 is included to account for the integration of force over distance, which leads to this formulation in physics.

Kinetic energy quantifies the energy that an object possesses due to its motion. As the velocity of an object increases, its kinetic energy increases exponentially because velocity is squared in the formula. This means that even a small increase in speed can result in a significant increase in kinetic energy. Additionally, this formula is foundational in mechanics and plays a crucial role in various applications, from understanding the motion of vehicles to analyzing the energy of particles in physics.

The other provided options represent different physical concepts:

• The formula mgh calculates gravitational potential energy, not kinetic energy.

• The expression Fd relates to work done when a force (F) acts over a distance (d).

• The equation pV pertains to pressure-volume work, commonly used in thermodynamics.

Understanding the distinction between these equations is essential for applying the correct principles in different contexts of physics and engineering.
