Newton’s second law (to be discussed in Chapter 5) states that acceleration is proportional to the force acting on an object and is inversely proportional to the object’s mass. What are the dimensions of force?
Answer:
According to ’s 2nd Law,
acceleration a ◊force F --------------------- (1)
From equations (1) and (2),
Thus, the dimension of force is equal to the dimension of the product of m and a.
