Resultant force + Work

Cards (7)

  • what is resultant force
    a single force (the sum of all other forces acting on an object)
  • what is the equation for work done
    work done = force x distance
  • what is the units for the work done equation
    Work done = W, in Joules J,
    Force = F, in Newtons N
    Distance= s, in metres, m
  • what is work done
    energy being transferred from the object doing the work to another form
  • if a book is lifted 1m in the air, and 2m to the right...
    work is done (against gravity) when moving 1m vertically, as its going against the direction of gravity
  • work done compared to displacement
    one joule of work is done when a force of one newton causes a displacement of one metres
    1 joule = 1 newton-metre
  • what happens when work is done against frictional forces
    a rise in temperature of the object
