Using conservation of energy means that potential energy is being converted into kinetic enegy and you can set the two equations equal.
PE = gmh and KE = 1/2mV2 become
gmh = 1/2mV2
mass can be algebraically eliminated
gh = 1/2V2
(9.8 m/s2)(12 m) = 1/2V2
117.6 = 1/2V2
multiply through by 2
235.2 = v2
take square root both sides
15 meters per second = velocity
According to the scientific law of conservation of energy the energy can be sustained by the bouncy ball indefinitely
After the car is dropped, it has NO gravitational potential energy.Before it's dropped, you can calculate the potential energy as mgh (mass x gravity x height). You can use 9.8 for gravity.
Yes. Under ideal circumstances - no air resistance, elastic collision (i.e., perfect bounce), the ball should bounce back to the same height from which it was dropped, due to conservation of energy. In practice, some energy is always lost, both due to air resistance and to a non-perfect bounce.
it is the difference of the potential energy when the body is on the table and from the position where it is dropped.
Gravitational potential energy describes how much energy a body has in store by virtue of having been elevated to a specific height. The formula to calculate gravitational potential energy is:.U = mgh.Where:U is the potential energym is the mass of the objectg is the acceleration due to gravity, andh is the height the object will fall if dropped.
Kinetic Energy or Potential energy= mass x gravity x height
no,due to physics the rebound weight and energy
There are several ways to solve this. An elegant way is using conservation of energy: If you neglect air resistance, after dropping 30 meters, all the potential energy is converted to kinetic energy. So, just calculate the potential energy at the top, assume the kinetic energy at the bottom is the same value, and solve the kinetic energy equation for speed.
It's not possible to calculate the answer with the information given.An object with a mass of 15 kg can be dropped from a building of any height.
The potential energy it had at height x when it was not moving is equal to the kinetic energy it will have as it is falling. Why? Law of the Conservation of Energy. Energy before will equal energy after.
wight x height
Height & weight.
Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.
The higher the height the ball is dropped from, the higher the height it will bounce to.
Relative gravitational potential energy.
The change in potential energy is equal to mass*gravity*change in height
Multiply its weight by its height.
KINETIC ENERGY NOTE : If a object is at rest it will have the potential energy but the MOVING body will always have kinetic energy
The energy in the ball is converted into other forms of energy ( sound energy/heat energy ) when it bounced on the floor.
Weight and height. The potential energy of an object is its weight times its height. The potential energy is turned into kinetic energy as the object is dropped. Potential energy is weight times height, kinetic energy is one half mass times velocity-squared. Mgh = ½ M V^2 To reach a speed of 10 m/s this equation can be solved to show that the object must be dropped through a height of 5.1 metres.
PE = mgh potential energy = mass x gravity x height
