Question

write about Newton's second law of motion and also obtain the expression of force​

Answer 1

Answer:

In equation form, Newton's second law of motion is a=Fnetm a = F net m . ... The weight w of an object is defined as the force of gravity acting on an object of mass m. The object experiences an acceleration due to gravity g: w = mg. If the only force acting on an object is due to gravity, the object is in free fall.
