Kinetic energy increases. The kinetic energy is related to the velocity, KE=1/2mv2. As an object falls freely the velocity increases and therefore the kinetic energy increases. or this will be a good answer to go by when an object has more potential energy. It will transform into kinetic energy.
The object has also potential energy
due to the presence of the gravitational field of the earth
E_pot = F_g h
Here h is height above ground and F_g=g m is the gravitational force
(g ... gravitational accelation 9.81 m/s^2, m=mass of object).
What is constant is total energy, i.e. the sum of potential and kinetic energy
E_total = E_kinetic + E_pot.
Indeed as the object falls, it is accelarated as its time-dependent speed obeys
v(t) = g t
hence
E_kinetic(t)l = m v^2/2 = m g^2 t^2 / 2.
At the same time, the potential energy decreases as the height above ground is getting smaller
E_pot(t) = m g h(t)
with
h(t)=h(0) integral_0 t dt' v(t) =h(0) - g t^2/2.
Now
E_kinetic(t) + E_potential(t) = m g^2 t^2 /2 + g h(0) - m g^2 t^2 /2 = g h(0).
An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly. An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly.
It will decrease if the object moves upward; decrease if the object moves downward.
The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
If the object's falling energy increases (this would happen if the object is already falling downward, and air resistance is small), then the kinetic energy will increase.
speed and potential energy
Temperature is the average Kinetic energy of molecules in an object. A hot object has more kinetic energy and a cold object has less kinetic energy.
An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly. An object has more kinetic energy when the temperature gets hotter. The particle's speed increase and begin to flow more rapidly.
Either the mass of the object or the speed of the object. However if the object is at rest, the increase of the mass will have no effect on its resting kinetic energy, which is zero.
It will decrease if the object moves upward; decrease if the object moves downward.
Increase.
The kinetic energy depends on both mass and speed. If either mass or speed increase, the kinetic energy will increase as well.
When there is an increase in an object or medium's temperature, its particles have increase kinetic energy. Temperature is the measure of the average amount of kinetic energy within an object or medium.
The kinetic energy of an object is proportional to the square of its velocity (speed). In other words, If there is a twofold increase in speed, the kinetic energy will increase by a factor of four. If there is a threefold increase in speed, the kinetic energy will increase by a factor of nine.
Increase its velocity
It speeds up.
If the object's falling energy increases (this would happen if the object is already falling downward, and air resistance is small), then the kinetic energy will increase.
