m=3 kg

g=9.8 m/s^2

h=2.5 m

P.E.=mgh

P.E.=3kg(9.8 m/s^2)(2.5m)

P.E.=73.5 J

What kind of force is bike skidding on road?

A bike skidding on a road is experience kinetic friction. This is a dissipative force, in that it takes energy out of a system when motion is in placed and puts the energy into heat.


Which types of heat transfer involve heat flow from hot objects to colder objects?

Yes! An object with a higher temperature will have a higher amount of thermal (heat) energy. The difference in amounts of thermal energy between a warmer and cooler object can be thought of as the difference in height of 2 coulmns or pillars of marbles. If you were to place a ramp across the 2 pillars and placed a marble on it then it would roll down toward the lower pillar. In the same way, heat energy is transferred from the hooter object to the cooler one. However as the heat energy goes from the hotter to the cooler, the temperature difference gets less (as more heat energy means hotter temperature). So the 2 objects will get closer and closer to the same temperature until they are both the same (we say they are in equilibrium). Going back to our pillar analogy, as more 'marbles' roll from the higher pillar to the lower pillar, the one gets shorter as the other gets taller in height until they are exactly the same height where the 'ramp' is flat and a marble would not roll in any direction. It might be important to note that this 'ramp' is known as a gradient, and that in nature, things will always wish to balance out if they can.


Is it true that the Ripple Effect describes the fact that an object placed in water displaces some of that water?

Yes. most of it. But at the end all that energy ends up as 'thermal energy' of the water.Before addressing the particular question let's first take a look at the 'big picture'of the situation of an object falling into water.Suppose an object originally rests at a given altitude over the water surface of aswimming pool. Then it's allowed to free drop to the pool and gets to rest in thebottom of the pool. (For simplicity's sake, object and pool's water are originally atthe same temperature and air drag on the object as it falls to the water's surface isnegligible).What is going to happen at the end, is that the object's original potential energy,measured from the bottom of the pool to the starting altitude, ends up in the pool'swater as thermal energy. Since we would most likely think of the experiment donewith an object not to big with respect to the pool like a bowling ball, and adropping height measured from the pools floor of just a few meters, the energy that the water will gain at the end once the water has recovered its originaltranquility, will be too small to be sensed by a household temperature.Now let's address the question 'in question', the description of the energy changes.1.- When the object free falls from its resting point to the water's surface, thekinetic energy developed comes from the potential energy lost at that point.2.- The object has a 'collision' with the water's surface and suffers a sharp drop ofof its kinetic energy. A 'collision' of two objects makes the particles that conformthe objects (atoms, molecules) vibrate (part of this vibrations are transferred to thesurrounding medium, e.g., air, as sound). Vibration of the atoms or molecules of abody are part of its 'thermal energy'. So, a rather small part of the kinetic energylost in the collision is transformed to thermal energy of the object and the waterinvolved in the collision. Most of the object's kinetic energy is invested indisplacing the water giving it motion (kinetic energy), local turbulence is developedand the 'outward ripples' (waves) on the water surface are consequence of thisaction.3.- The object will continue making its way to the bottom losing its remainingpotential energy, giving motion to the water surrounding it, and although in verysmall amount, some of it is invested in friction that ends as thermal energy in thesurroundings (the water).4.- In conclusion, all the mechanical energy that the object gives to the water inthis hypothetical experiment in a pool ends up in the pool's water thermal energy.

What is difference between potential and kinetic energy give two examples?

If the object is placed at height, it has potential energy and when this object falls down, this potential energy is converted to kinetic (kinesis means movement) energy. If we have to lift object at height , we have to spend energy, witch is released during fall of the object. Example is when water comes down in hydroelectric power station potential energy is converted into kinetic energy. Witch is used to rotate wheel, creating electricity.


How can potential energy be increased and decreased?

Potential energy is pretty much the potential for kinetic energy. The less kinetic energy there is, the more potential... On the other hand, if you need gravitational potential energy, then the higher the object is placed above the ground, the more GPE it has.


When is potential energy transformed into kinetic energy?

As soon as the object is allowed to move, potential energy starts getting transformed into kinetic energy. For example the object placed on height. As soon as it is allowed to fall, the potential energy starts getting converted into kinetic energy. It is maximum at the time the object touches the ground.

What is in potential?

A little complicated, but here are two examples: In electric fields, a potential of 5 Volts means that if a 1 coulomb charge were placed there, it would have a potential energy of 5 Joules. In gravitational field, a potential of 5 J/kg means that if a 1 kilogram mass were placed there, it would have a potential energy of 5 Joules.
