Potential energy is the energy which is stored in a body when a certain force is applied on a body or work done on it.
Stretching a rubber band or spring, punching a non elastic ball, binding a cracker with string. In this the energy is stored in the objects after applying force on them and when released it is converted to other forms of energy like kinatic energy, chemical energy or sound
Gravitational potential energy is the energy stored in the object when work is done or applied in opposition with the gravitational force acting on it. e. g. water stored in dam, ball thrown in air or an elevator going up.
Obviously gravitational potential energy is the subset of all potential energies stored in the body..
I'm sorry, I just saw this. I hope I'm not too late.
GPE = mass * gravity * height
height = GPE/(mass * gravity)
height = 50/(1/2 * 9.8)
height = 10.2041 Meters
Answer: 8.4 kW•hr
Explanation:
600 W • (14 hr) / (1000 W/kW) = 8.4 kW•hr
air beomes more dense
below dewpoint = a dew forms ... wet underfoot.
cold enough = frost ???
Answer:
Speed
Explanation:
If a vehicle hit any other object then its speed will slow down or some time the vehicle will stop its depends on the force exerted by other object on the vehicle.
The change in speed of vehicle is due to momentum because momentum is always conserved. So to conserve the momentum the speed of the vehicle decreases because after hitting the overall mass is increases.
