GPE & Gravitational Field

• What is weight?

  The force exerted on an object due to gravity.
• What is gravitational potential energy?


  Gravitational potential energy is the energy possessed by an object due to its position in a gravitational field.
• What is the formula for gravitational potential energy?


  GPE = mgh

  m x g x h
• What is gravitational field strength?

  The strength of a gravitational field around an object
• What are the units of weight?

  Newtons (N)
• Which 2 factors affect the strength of gravitational attraction between two objects?

  1. The masses of the objects
  2. the distance between them
• What is gravity?

  An invisible force that pulls objects towards eachother
• What is the formula for weight?

  Weight = mass x gravity (mg)
