Tamsen and Vera imagine visiting another planet, planet X, whose gravitational acceleration, gX, is different from that of Earth
's. They envision a pendulum, whose period on Earth is 2.243 s, that is set in motion on planet X, and the period is measured to be 2.000 s. What is the ratio of gX/gEarth? Neglect any effects caused by air resistance.
Objects in motion tend to stay in motion unless acted upon by an unbalanced force. For example if the force of friction is not balanced with the applied force the object will accelerate in the direction of the applied force.
