What does the law of conservation of energy state about energy in a closed system?

Newton's law of universal gravitation states that the force f between two masses, m1 and m2, is given below, where g is a constant and d is the distance between the masses. find an equation that gives an instantaneous rate of change of f with respect to d. (assume m1 and m2 represent moving points.)

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
