What is the primary factor that affects the potential energy of an object elevated above the ground?, Speed of the object, Height of the object, Color of the object, Shape of the object, A 2 kg book is placed on a shelf 3 meters high. Calculate its gravitational potential energy (assuming g = 9.8 m/s²)., 19.6 J, 57.8 J, 58.8 J, 29.4 J, If two objects have the same height above the ground but different masses, how will their potential energies compare?, The object with greater mass will have more potential energy., Both objects will have the same potential energy., The object with lesser mass will have more potential energy., Potential energy is not dependent on mass., Why might an object with significant potential energy not cause damage if it falls?, It falls in a vacuum where air resistance is absent., It is held in place by an external force., It is very light and thus cannot cause damage., Its kinetic energy is absorbed by a cushion or soft material., Which of the following is a design of a simple experiment to demonstrate the conversion of potential energy to kinetic energy using household items., Roll a marble down a sloped board and measure its speed., Drop a feather and a stone simultaneously and observe their fall., Swing a pendulum and measure the height it reaches on each side., Freeze water in a balloon and drop it from a height to observe splatter..
