Question 1

formula for weight and units

Answer 1

weight= gravitational field strength x mass

weight = Newton (N) gravity = (N/kg) mass = (kg)

Question 2

formaula for work done (energy) and units

Answer 2

work done = force x distance

W.D = Joules force = Newtons distance = Metres

Question 3

formula with spring constant, force and extension and units

Answer 3

force = spring constant x extension

force = Neuton S.C= (N/m) extension (m)
