Study Notes
Mechanical Energy
- Kinetic energy is the category of mechanical energy associated with an object's motion.
- The formula for calculating kinetic energy is
K = 0.5mv^2, wheremis the mass of the object andvis its velocity.
Potential Energy
- Gravitational potential energy is the form of mechanical energy associated with an object's position in a gravitational field.
- The formula for calculating gravitational potential energy is
U = mgh, wheremis the mass of the object,gis the acceleration due to gravity, andhis the height of the object above the ground.
Categories of Mechanical Energy
- The two main categories of mechanical energy are kinetic energy and potential energy.
