• Examples of Work


  • Lifting • Pushing • Pulling • Stretching • Compressing • Turning • Winching
• Work Formula


  Work (W) = Force (F) x Distance (d)
• Doing Work


  A transfer of energy from one object or system to another
• What is potential energy?

  Potential energy is the energy an object has due to its position or state, such as height or compression.
• What is Gravitational Potential Energy (GPE)?


  GPE is the energy an object has due to its height or position above the ground or a reference point.
• What happens to GPE when an object falls?

  GPE is converted to Kinetic Energy (KE) as the object gains speed and gains height.
• What is Measurable Potential Energy (MPE)?

  MPE is the energy an object has due to its position or state, taking into account the reference point or frame of reference.
• What is the relationship between PE and KE?

  PE and KE are related: energy can be converted from one form to the other, and the total energy remains constant unless an external force acts on the object.
• What is Elastic Potential Energy (EPE)?


  EPE is the energy stored in stretched or compressed materials, such as rubber bands or springs.
• What happens to EPE when an elastic material is stretched or compressed?

  EPE is converted to Kinetic Energy (KE) as the stretched or compressed material releases its stored energy.
• What is the difference between Potential Energy (PE) and Kinetic Energy (KE)?

  PE is energy stored in an object due to its position or state, while KE is the energy an object has due to its motion.
• What is the Law of Conservation of Energy?

  The total energy of an isolated system remains constant over time, as energy can be converted from one form to another, but not created or destroyed.
• What is the relationship between PE and kinetic energy in circular motion?

  In circular motion, the sum of PE and KE remains constant, as the object's PE is converted to KE as it moves around the circle.
• What is Rotational Kinetic Energy (RKE)?

  RKE is the energy an object has due to its rotation, and it can be converted from Potential Energy (PE) as the object moves around a circular path.
• What is the relationship between PE and RKE in a pendulum?

  In a pendulum, PE is converted to RKE as the bob swings back and forth, and the sum of PE and RKE remains constant.
• What is the concept of "stored energy" in PE?

  Stored energy in PE refers to the energy an object has due to its position or state, which can be converted to Kinetic Energy (KE) or work done.
• What is the difference between Gravitational Potential Energy (GPE) and Elastic Potential Energy (EPE)?

  GPE is the energy an object has due to its height or position above a reference point, while EPE is the energy stored in stretched or compressed materials.
• What is the role of external forces in energy conservation?

  External forces can cause a system to gain or lose energy, affecting the balance of PE and KE, but the total energy remains constant in accordance with the Law of Conservation of Energy.
