- Q1What are the two types of energy transformation?Single and MultipleFirst and SecondGood and BadMaximum and Minimum30sMS-PS3-5
- Q2An example of a single transformation isrunning a race (chemical to mechanical to thermal)photosynthesis (electromagnetic to thermal to chemical)Starting a car (chemical to electrical to mechanical)toasting a bread (electrical to thermal)30sMS-PS3-5
- Q3An example of a multiple transformation iscooking food (themal to chemical)turning on the lightbulb (electrical to light to heat)Lighting a match (mechanical to chemical to thermal to light)30sMS-PS3-5
- Q4What is happening as the ball goes from point A to point DThe potential energy is the sameThe potential energy is doubledThe potential energy is decreasingThe potential energy is increasing30sMS-PS3-5
- Q5What is happening as the ball goes from point A to point DThe kinetic energy is the sameThe kinetic energy is increasingThe kinetic energy is decreasingThe kinetic energy is doubled30sMS-PS3-5
- Q6Which of these DOES NOT shows the Law of conservation of Energy?Energy is transformed from one form/type to anotherEnergy is not destroyed.Energy is transferred from one object to anotherEnergy can be created at some point30sMS-PS3-5
- Q7Why would an object thrown at a higher altitude go further than an object thrown at a lower altitude?Because the density is lower at high altitude and this causes less frictionBecause it is highThis is false because both objects will go the same distanceBecause the density is lower at low altitude causing gravity to act30sMS-PS3-5
- Q8Which of these waves require a medium to travel?Sound wavesX-raysRadio wavesMicrowaves30sMS-PS3-5
- Q9When the ocean waves break, where does the energy go?Back in the waterto the diversto the animalsAir and sea shore30sMS-PS3-5
- Q10At what point does the ball have the highest kinetic energy?DCBA30sMS-PS3-5
