Study Notes
Energy and Kinetic Energy
- An object possesses kinetic energy due to its motion.
- Kinetic energy is defined as the energy an object has because of its velocity.
- An object maintains its kinetic energy unless it experiences an external force that alters its state of motion.
- The equation for kinetic energy of a non-rotating object in classical mechanics is represented as ( E_k = \frac{1}{2}mv^2 ), where ( m ) is mass and ( v ) is velocity.
- The equation ( E_k = \frac{1}{2}mv^2 ) serves as a good approximation in classical mechanics, particularly when the speed ( v ) is much less than the speed of light.

- Focuses on the study of kinetic energy.
- Served as rector at the Universidad Simón BolÃvar.
Conservation of Mechanical Energy
- According to the principle of conservation of mechanical energy, an isolated system subjected only to conservative forces retains constant mechanical energy.
- If an object moves opposite to a conservative net force, its potential energy will increase.
- In real-world systems, nonconservative forces, such as friction, typically result in energy loss.
- In elastic collisions, the kinetic energy is conserved.
- The equivalence between lost mechanical energy and an increase in temperature was discovered by James Prescott Joule.
