The kinetic energy, Ek, of a body of mass, m, travelling at a speed, v, is given by;
Ek = 1/2 mv2
Ek can be increased by either increasing the mass of the object (but the additional mass must also travel at speed, v), or by increasing its speed. It is normally more practical to increase the speed of the object.

How does the addition of heat to a liquid affect its average kinetic energy?
Adding heat to a liquid increases the average kinetic energy of its molecules. This increase in kinetic energy causes the molecules to move faster, leading to higher temperature and possibly phase change from liquid to gas if enough heat is added.
What would increase a temperature of a substance?
An increase in energy input, such as heat transfer from a heat source or mechanical work, would increase the temperature of a substance. This causes the particles in the substance to move faster, leading to an increase in kinetic energy and temperature.
What would be the kinetic energy of particles of gas when it compressed in a cylinder?
When a gas is compressed, its temperature tends to increase. That means that the average kinetic energy per particle also increases.
If a stone is pushed from the top of the hill what kind of energy would it have halfway down the hill?
The stone would have a combination of potential and kinetic energy halfway down the hill. The potential energy would decrease as the stone moves lower, while the kinetic energy would increase as the stone gains speed.
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.
What would cause the greatest increase in an object's kinetic energy?
Increasing the object's velocity would cause the greatest increase in its kinetic energy. This is because kinetic energy is directly proportional to the square of the object's velocity.
Would increasing the speed of an object increase or decrease its kinetic enregy?
Increasing the speed of an object would increase its kinetic energy. Kinetic energy is directly proportional to the square of the object's speed, so as the speed increases, the kinetic energy will increase by a greater amount.
If you were able to increase the kinetic energy of the molecules inside your body your body temperature would?
increase as kinetic energy is directly related to temperature. The molecules would move faster, increasing collisions and thermal energy, causing an increase in body temperature.
How does the addition of heat to a liquid affect its average kinetic energy?
Adding heat to a liquid increases the average kinetic energy of its molecules. This increase in kinetic energy causes the molecules to move faster, leading to higher temperature and possibly phase change from liquid to gas if enough heat is added.
What would always lead to an increase in the average kinetic energy of a gas?
Heating it.
What was the effect on the skate's maximum kinetic when he was placed further down the ramp?
The skate's maximum kinetic energy would increase as it moves further down the ramp due to the conversion of potential energy into kinetic energy. As the skate descends, it gains speed and therefore its kinetic energy increases.
What would increase a temperature of a substance?
An increase in energy input, such as heat transfer from a heat source or mechanical work, would increase the temperature of a substance. This causes the particles in the substance to move faster, leading to an increase in kinetic energy and temperature.
What would be the kinetic energy of particles of gas when it compressed in a cylinder?
When a gas is compressed, its temperature tends to increase. That means that the average kinetic energy per particle also increases.
How can a trucks kinetic energy can be increased without increasing its speed?
Drive alongside it in another vehicle and then move stuff onto the truck. This will increase the mass of the [whole] truck and so increase its KE. This is dangerous so do not try it!
What will happen to kinetic energy if vilocity is doubled?
Kinetic energy = (1/2)mv2, that is, (1/2) x mass x speed squared. As you can see, it is proportional to the square of the speed. Twice the speed would cause four (22 or 2 x 2) times the kinetic energy.
Kinetic energy increases as?
Kinetic energy increases as speed or mass increases, or as potential energy decreases.Velocity increases(The kinetic energy of an object would also increase as its mass increases, but this doesn't usually happen.)
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.
