Work Done and Energy Transfer

• What happens when a force causes an object to move?

  Energy is transferred and work is done
• How is work calculated when a force moves an object?

  Using the equation: Work = Force x Distance
• What does the equation W = F x d represent?

  Work done equals force times distance
• What units are used for work, force, and distance?

  Work in joules, force in newtons, distance in meters
• What does work done by a force on an object depend on?

  It depends on the force and distance moved
• What is the work done when a force of one newton moves an object one meter?

  One joule
• What happens to the temperature of an object when work is done against frictional forces?

  The temperature of the object increases
• How does work done against friction affect an object's energy?

  It converts mechanical energy into thermal energy
• What is the relationship between work done and the displacement of an object?

  Work done is directly related to displacement
• What is the effect of a force acting on an object in terms of work done?

  It causes displacement and transfers energy
• What is the significance of the direction of force in calculating work done?

  Work is done only if force and displacement are in the same direction
• What is the formula for calculating work done against friction?

  Work = Force x Distance moved against friction
• How does the work done by a force relate to the energy transferred to an object?

  It is equal to the energy transferred to the object
• What happens to the energy of an object when work is done on it?

  The energy of the object increases
• What is the unit of work in the International System of Units (SI)?

  Joule
• What is the effect of doing work against gravitational forces on an object?

  It increases the object's gravitational potential energy

  15 joules
• What is the relationship between work done and energy in a closed system?

  Work done is equal to the change in energy
• How does the concept of work relate to the laws of thermodynamics?

  Work is a form of energy transfer in thermodynamics
• What is the effect of work done on an object in motion?

  It can change the object's speed or direction
• What happens to the energy of an object when work is done on it by an external force?

  The energy of the object increases
