Gaining kinetic energy 'E' amounts to saying that the momentum of an object increases.
E = p^2 / 2m
where p is momentum and m is mass. (Momentum is just mass times speed.)
So, to increase the speed the kinetic energy has to change. In other words, if you set the kinetic energy to any value you like and keep it constant, there won't be a speed up.
What is the change in kinetic energy? You can just as well ask what is the change in momentum. Physicists have chosen the latter question and call the change in momentum 'the force'.
F = dp / dt
where F is force and d/dt means derivation with respect to time.
It is the pushing force acting on objects that makes them gain speed. Kinetic energy is usually something that you calculate at the end when you have found out what the forces in your problem are and what the momentum is as a function of time.

What is the speed of an object increases its kinetic energy .?
The kinetic energy depends on both mass and speed. If either mass or speed increase, the kinetic energy will increase as well.
What happens to an object as its kinetic energy increase?
It speeds up.
Object hanging on a tree a kinetic or potential energy?
Potential energy is the energy contained in the position of an object, so object hanging on a tree would be potential energy.
How do you make objects particles move faster?
Increase the kinetic energy by heating the object up.
What is the condition of an object if it has kinetic energy?
Kinetic energy is the energy of movement.
How does temperature increase or decrease?
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.
What makes an object have more 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.
What increase as an objects kinetic energy increases?
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.
What will happen to the kinetic energy of the object as it falls?
Increase.
What is the speed of an object increases its kinetic energy .?
The kinetic energy depends on both mass and speed. If either mass or speed increase, the kinetic energy will increase as well.
How do particles of matter react to an increase of temperature?
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.
What is the relationship between speed and kinetic energy?
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.
What do you have to change for an object to have more kinetic energy?
Increase its velocity
What happens to an object as its kinetic energy increase?
It speeds up.
What happens the the kinetic energy of a falling object?
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.
What two things do you need to increase the kinetic energy of an object?
speed and potential energy
What happens to an object kinetic energy if the object speed increases?
The kinetic energy will increase. Kinetic energy is defined by K=one half mv2 where m is the mass of the object, and v is the velocity of the object. The greater the velocity, the greater the kinetic energy. Since the velocity is squared, increasing it will cause the kinetic energy to grow much faster than if you increased the mass.
