(a) Which force can be measured by a spring balance when a load is hanged at its lower
end? What is its unit?
(b) State the factors that determine the magnitude of force acting on an object?
(c) The reading on spring balance will give you a measure of which force when the block
shown in the figure just begins to move?
(d) If now an additional weight is put on the block what change will you observe in
reading of spring balance? Why?
Answers
Answer:
a) Spring balances provide a method of mass measurement that is both simple and cheap. The mass is hung on the end of a spring, and the deflection of the spring due to the downwards gravitational force on the mass is measured against a scale.
b) force
c) You need to apply some force. Note down the reading on the spring balance when the brick just begins to move. It gives you a measure of the of force of friction between the surface of the brick and the floor.
d) sorry mate, I don't about this.
