- Q1Which of the following factors affects the potential energy of an object?The shape of the objectIts height above the groundThe color of the objectIts speed30s
- Q2What primarily affects the kinetic energy of a moving object?The color of the objectIts speedThe texture of the object's surfaceThe temperature of the object30s
- Q3Which of the following scenarios would increase an object's potential energy?Increasing its speedCooling it downRolling it down a hillLifting it to a higher elevation30s
- Q4What is the relationship between kinetic energy and mass?Kinetic energy is independent of massKinetic energy is only related to heightKinetic energy decreases with massKinetic energy increases with mass30s
- Q5How does increasing the speed of an object affect its kinetic energy?It increases the kinetic energy significantlyIt decreases the kinetic energyIt has no effect on the kinetic energyIt only slightly increases the kinetic energy30s
- Q6Which factor does NOT affect the potential energy of an object?The strength of gravityThe object's heightThe object's colorThe object's mass30s
- Q7What happens to the potential energy of a ball as it is thrown upward?It decreases as the ball gains heightIt is only affected by its massIt remains the same regardless of heightIt increases as the ball gains height30s
- Q8Which two types of energy are involved in the process of a roller coaster moving up and down?Thermal energy and nuclear energySound energy and light energyChemical energy and elastic energyPotential energy and kinetic energy30s
- Q9In which situation would an object's kinetic energy be the greatest?When it is moving at its highest speedWhen it is moving slowlyWhen it is at restWhen it is on a flat surface30s
- Q10What can be said about the relationship between potential energy and gravitational force?Potential energy only depends on speedPotential energy increases with height in a gravitational fieldPotential energy decreases with height in a gravitational fieldPotential energy is not affected by gravitational force30s
- Q11What happens to the speed of sound as the temperature of the air increases?The speed of sound decreasesThe speed of sound becomes unpredictableThe speed of sound increasesThe speed of sound remains the same30s
- Q12Which of the following temperatures would most likely result in the fastest speed of sound in air?15 degrees Celsius-10 degrees Celsius0 degrees Celsius30 degrees Celsius30s
- Q13At which temperature does the speed of sound in air reach approximately 343 meters per second?0 degrees Celsius50 degrees Celsius100 degrees Celsius20 degrees Celsius30s
- Q14How does a decrease in temperature affect the speed of sound in air?The speed of sound decreasesThe speed of sound increasesThe speed of sound doublesThe speed of sound remains constant30s
- Q15What is the primary reason why sound travels faster in warmer air compared to colder air?Molecules move faster in warmer airSound waves are louder in warmer airWarm air is denser than cold airThere are more air molecules in warmer air30s
