If two objects are moved closer together so that the distance between them is one-third the original distance what is the gravitational force after the object is moved

Iflow from a warmer object to a cooler object until both objects are the same temperature what am i?

Very large accelerations can injure the body, especially if they last for a considerable length of time. one model used to gauge the likelihood of injury is the severity index ( ), defined as =/ . in the expression, is the duration of the accleration, but is not equal to the acceleration. rather, is a dimensionless constant that = the number of multiples of that the acceleration is equal to. in one set of studies of rear-end collisions, a person's velocity increases by 13.7 km/h with an acceleration of 36.0 m/s2 . let the + direction point in the direction the car is traveling. what is the severity index for the collision?

Why is the energy that results from a roller coaster's position at the top of a hill referred to as potential energy?
