    A vector has direction and Magnitude
  • True or false? Time is a vector quantity
    False
  • What is the difference between a contact and non-contact force?
    Contact: Direct physical contact between objects. Non-contact: Acts at a distance without physical contact.
  • Explain the difference between mass and weight?
    Mass: Amount of matter in an object. Weight: Force of gravity acting on an object's mass.
  • What is the formula for calculating weight?
    Weight= Mass x Gravitational Field Strength
  • What is a free body diagram?
    A diagram that represents the forces acting on an object.
  • What is a resultant force?
    The overall force acting on an object, taking into account both magnitude and direction.
