An object has a kinetic energy of 810 j after falling a certian distance if the mass of the object is 20 kg what is the speed of the object at this time?
The formula for kinetic energy, Ek, could not be simpler.
Ek = (1/2)mv2, where m is mass (in kg) and v is velocity (in m s-1). If you prefer, you could write Ek = mv2/2.
or, 810j=1/2*20Kg*v2
or,v2=810j*2/20Kg
or,v=sqrt of 81
so,v=9m s-1

What kind of energy possessed water falling from a dam?
Kinetic energy
A boulder falling through the air has what type of energy?
The boulder falling through the air has kinetic energy. This is the energy possessed by an object in motion.
What happens the the kinetic energy of a falling object?
As a falling object descends, its potential energy (due to its position above the ground) is converted into kinetic energy (energy of motion). This kinetic energy increases as the object accelerates towards the ground. When the object reaches the ground, all of its potential energy is converted into kinetic energy.
How is the increase in thermal energy of a cylinder related to the vertical falling distance?
The increase in thermal energy of a cylinder is not directly related to the vertical falling distance. The thermal energy change is primarily influenced by factors such as the material and mass of the cylinder, initial temperature, and heat transfer mechanisms. The falling distance may affect the kinetic energy of the cylinder, but this does not have a direct impact on its thermal energy change.
What form of energy is a falling rock?
That is a trick question, but I believe it is kinetic energy.

A falling rock has kinetic energy?
Yes, a falling rock has kinetic energy because it is in motion. As the rock falls, its gravitational potential energy is being converted into kinetic energy due to its movement and speed.
What is the distance between kinetic and potential energy?
Kinetic and potential energy are a type of energy, not a measurement of distance.
Does a strawberry have kinetic energy?
If the strawberry is moving, it has kinetic energy. Anything with a mass and velocity has kinetic energy.
What is energy possessed by moving or falling bodies?

What is energy from potenttial energy kinetic energy would be what?
A falling rock. In the air it has potential energy, as it falls it gets kinetic energy.
