WebOct 27, 2024 · Since a change in either speed OR direction means a change in velocity, the object’s velocity is not constant. Is a falling object constant? The force of gravity causes objects to fall toward the center of Earth. The acceleration of free-falling objects is therefore called the acceleration due to gravity. It is constant at any given location ... WebThis try is the only laboratory determination of gravity that does not suspend the test mass from one support system.
