The mechanical energy is stored in the spring as potential energy within the pullback toy and when you release it, it gets converted into kinetic energy.
Hence cycle is
Mechanical --- Spring (Potential)--- Kinetic
gravitational potential energy --> kinetic energy
Assuming it just rolls down a slope, without the engines working: gravitational potential energy will be converted to kinetic energy. The kinetic energy will eventually be converted to heat energy.
The water runs down hill. That's why all rivers lead to the sea.
The act of rolling is showing kinetic energy because it is movement, but we should always look at energy change. As you go down hill, potential energy is converted to kinetic energy.
two, one is the resultant weight on the slope and = cosine (slope angle) * mass two is the force on the object and acts parralel to the the slope and = sin (slope angle) * mass
describe the wave pulse that travels down the slinky?
the change of rise over run. a positive slope goes up and a negative slope goes down
Assuming it just rolls down a slope, without the engines working: gravitational potential energy will be converted to kinetic energy. The kinetic energy will eventually be converted to heat energy.
Rolling down a slope.
rise
It's because of kinetic energy
It is called an avalanche
As gravity pulls water down a slope, the water's potential energy changes to kinetic energy that can do work.
Both kinetic and potential energy vanish.
From a stand still, going down a hill on skates you are converting potential energy into kinetic energy.
While a sled slides down a hill, it has kinetic energy(Ek = 1/2mv2).At the top of the slope, while not moving, it would have possessed gravitational potential energy. As it moves down the slope, however, some energy is converted to heat and sound in accordance with the Law of the Conservation of Energy which states that matter cannot be created or destroyed but is converted from one form to another.
=1 A landslide is a mass of earth or rocks that slides down a slope==2=
Once the skiers go uphill by a cable car or lift, they gain potential energy. This potential energy is converted into kinetic energy once the skiers start to ski down the slope.
