Question

For a system of N particles write down the general formula for total internal force in terms of
summation notation How many terms the summation will have it expanded?​

Answer 1

Answer:

In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Accelerations are vector quantities (in that they have magnitude and direction). The orientation of an object's acceleration is given by the orientation of the net force acting on that object
