At halfway, the forces are equal. At three quarters of the way down, it will have three times the kinetic energy as it does potential (having travelled three times the distance than is left). So at 7.75m into the fall it's kinetic energy will be triple it's potential energy.

What two properties does the amount of potental energy depend upon?
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.
Why would the final kinetic energy before impact be less the initial potential energy of an object dropped from a kilometer height?
It is easiest to think of initial potential energy as the "distance" the object is able to fall. If it has not fallen the distance yet, then of course kinetic energy would be less.
What characteristic is associated with potential energy rather than kinetic energy?
Potential energy is associated with height. Kinetic energy is associated with motion.
A girl throws a ball 15 m into the air the ball has the maximum potential energy at a height of?
The ball has the highest potential energy at its maximum height (15m in the air). At the beginning, the ball has only kinetic energy and no potential energy. But as the ball travels upward, kinetic energy is converted into potential energy. When the ball changes direction, there is no kinetic energy, as all of it is now potential energy. As the ball returns back down, potential energy is converted back into kinetic energy.
What happens to potential energy when rock falls?
When the rock is high up but has not been dropped yet, it has a lot of gravitational potential energy because of its position. PE = (mass) x (G) x (height) After it is dropped, the lower it goes, the less potential energy it has. That bit of missing potential energy has become the kinetic energy that it now has on account of its speed of descent. KE = 1/2 (mass) x (speed)2
What is the kinetic energy of a ball when it is dropped from a height and it falls on a table?
it is the difference of the potential energy when the body is on the table and from the position where it is dropped.
What happens to the object's potential energy when it is dropped?
When an object is dropped, its potential energy decreases. This is because potential energy is a result of an object's position or height above the ground. As the object falls, it loses height, which leads to a decrease in potential energy. At the same time, the object gains kinetic energy, which is the energy of motion.

Of the 7 different forms of energy which are potential and which are kinetic?
Potential energy is because of height. Kinetic energy is because of motion.
Why does a body exerts more force on ground when it is dropped from a certain height than when it at rest at the ground although in both the cases mass and acceleration is constant See discussion too?
Interesting question. But when the object is at rest the potential energy of the object is 0, on the surface that is. When it is on a height h it's potential energy increase and when it is dropped from that height all that potential energy gets converted to kinetic energy just before hitting the ground. This extra force comes from this kinetic energy.
Is kinetic energy a force motion or energy?
Kinetic energy is energy. It can be transformed to other types of energy. And as energy it can be applied to do work. If an elastic ball is dropped from a given height, it will develop kinetic energy at the expense of its potential energy. An instant before collision with the floor, its kinetic energy amounts to the original potential energy of the ball with respect to the floor. (if we can neglect air resistance).
What is the kinetic energy of an object weighing 65 kg dropped from a height of 40m?
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.

Is it possible to have kinetic and potential energy at the same time?
yes it is, but you can only have kinetic energy of the object is in motion and potential energy if the object is any height above zero
What type of energy is stored in thermal energy-kinetic or potential energy?
It consist both, the kinetic as well as potential energy. Justification: As per potential energy formula mgh m-mass in kg g- Acceleration due to gravity h - Height if any of the above parameters does not have zero value then their should be a potential energy. Kinetic energy does exist.
