I-True or False

1.Kinetic energy is possessed by moving object.
2.It is affected by the mass of an object and the height/distance from the ground.
3.The bigger the mass,the higher is the kinetic energy.Thus,they are directly proportional.
4.Kinetic energy is also affected by the speed of a moving object.
5.A truck driven down a hill has a higher kinetic energy than a person running down a hill.
6.Sound is produce by a vibrating object
7.Particles move fast and have more kinetic energy when the temperature is high.
8.At daytime,sound travel slower at the nighttime
9.The factors that affect the speed of sound are humidity,temperature and density
10.Sound travels fastest when the temperature is high​
