<span> it is electromagnetic waves that are made up of oscillating magnetic and electric fields </span>
Kinetic energy:
1) A car traveling down the road has less kinetic energy than a semi-truck and traveling at the same speed because the car's mass is much less than the truck's.
2) A river flowing at a certain speed possesses kinetic energy because the water has a certain mass and it also has velocity.
3) An insect flying has a small amount of kinetic energy because its mass and velocity are relatively small.
Potential Energy:
1) The food we eat has chemical potential energy because as our body digests it, it provides us with energy for basic metabolism.
2) A stretched spring in a pinball machine has elastic potential energy and can move the steel ball when released.
3) When a crane swings a wrecking ball up to a certain height, it gains more potential energy and has the ability to crash through buildings.
To convert a quantity in kilograms to pounds, you simply multiply by 2.2 lb/kg.
(7 kg)(2.2 lb/kg) = 15.4 lb.
Constant velocity means............
applied force=frictional force=p=kinetic friction coefficient*mg=0.26*10*9.8=?
now we know .... work=force*distance=0.26*10*9.8*0.87joule
plz feel free to ask if u hv any confusion!!
