Apuntes

A moving object has energy associated with its motion Whenever work is done, energy is transformed or is transferred from one system to another system Energy can be present in an object or a system that is at rest Measurements of energy and work are expressed in joules Potential Energy: The energy that an object has because of the position, shape, or condition of the object Elastic Potential Energy: Potential energy where an object’s stretched or compressed to increase or decrease the distance between its parts Gravitational Potential Energy: Potential energy that results from the gravitational attraction between two or more objects Gravitational potential energy depends on both mass and height Gravitational Potential Energy Formula: mass x free-fall acceleration (g) x height Kinetic Energy: The energy that an object has because it is moving Kinetic energy depends on both the mass and the speed of an object Higher Mass = Higher Kinetic Energy Higher Speed = Higher Kinetic Energy Kinetic Energy Equation: ½ x mass x speed squared Kinetic energy is expressed in joules ( kg x m² / s² ) Kinetic energy depends on speed more than...
