Question

Describe an expression for force from second law of motion​

Answer 1

Answer:

In equation form, Newton's second law of motion is a=Fnetm a = F net m . This is often written in the more familiar form: Fnet = ma.  

If the only force acting on an object is due to gravity, the object is in free fall. Friction is a force that opposes the motion past each other of objects that are touching.
