AIM
To verify Newton’s second law and to determine the friction force acting on the wooden block.
BACKGROUND THEORY
When a wooden block (cart) slides over a surface, the net force acting on the block is given by,
In the following set up, the applied is given by,
(‘m’ is the mass suspended)
The net force provides acceleration ‘a’ to the wooden block. Hence,
(‘M’ is the mass of the wooden block)
