- Q1As a boulder rolls from the top of a hill to the bottom, how does its potential and kinetic energy change?potential and kinetic energy both increasepotential decreases and kinetic increasespotential increases and kinetic decreasespotential and kinetic energy both decrease60s
- Q2At which point in the rollercoaster's journey is its potential energy the greatest?YZXW60s
- Q3The pictures shows a light bulb attached to a hand generator. What energy transformation occurs as the handle of the generator is turned?Thermal to solarelectrical to lightSolar to lightMechanical to light60s
- Q4The drawing shows two identical airplanes at an air show. The airplanes are flying at the same speed. Airplane W is flying 50 m higher than Airplane X. Which statement best describes the energy of the two airplanes?Airplane W has a greater kinetic energy than Airplane X.Airplane X has more gravitational potential energy than Airplane WThe two airplanes have the same kinetic energy but different gravitational potential energiesThe two airplanes have the same gravitational potential energy but different kinetic energies120s
- Q5A teacher rubbed a match against a piece of sandpaper. The match started to burn. Which statement best describes the energy changes that occurred?The light energy and thermal energy stored in the match changed to chemical energyThe thermal energy stored in the match changed to light energy and chemical energyThe light energy and thermal energy stored in the match changed to mechanical energyThe chemical energy stored in the match changed to thermal energy and light energy120s
- Q6Which statement describes the energy changes that occur when water in a tea kettle is heated on a stove that uses natural gas?Some of the energy in the natural gas transforms into sound energy when the water becomes hot. Then some of the sound energy changes into light energy when the kettle becomes warmSome of the light energy in the natural gas transforms into chemical energy in the water. Then some of the chemical energy changes into kinetic energy when steam leaves the kettle and into sound energy when the water boilsSome of the chemical energy in the natural gas transforms into thermal energy, which heats the water. Then some of the thermal energy changes into sound energy when the water forms steam and steam leaves the kettleSome of the electrical energy in the natural gas transforms into thermal energy, which causes the water to form steam. Then some of the thermal energy changes into sound energy and light energy when the steam leaves the kettle120s
- Q7A stationary object may havepotential energyaccelerationvelocitykinetic energy120s
- Q8Which is the best example of something that has kinetic energy?a car parked on a steep hilla tennis ball rolling across the courta piece of coal before it's burneda picture hanging on the wall120s
- Q9Conservation of Energy means thatenergy can be created but not destroyedenergy can both be created and destroyedenergy can be destroyed but not createdenergy can neither be created nor destroyed120s
