What two factors determine how much kinetic energy a moving energy?
Do you mean "a moving object"? Then the answer is mass & speed.
What has more inertia a fast moving object or slow?
no, if the have the same mass. if they don't, then if (a) the mass of A object and (b) the mass of B, while C the velocity of A and D the velocity of B you have to find this: Z=(a*C^2)/(b*D^2). if Z is greater than 1, object A has more kinetic eneregy. if it is equal to 1 they have the same kinetic energy, and if it is less than 1 then B has more kinetic energy.
The faster particles move the more energy they have?
In mechanics, a study within physics, when we talk about the energy of motion, we are talking about kinetic energy. When we look at an object's kinetic energy, it's energy of motion, we see it is related to how much mass the object has, and how fast it is moving. Naturally, there is an expression or formula for this: Ek = 1/2 mv2 The kinetic energy (Ek) equals one half the mass (m) times the square of the velocity (v).
How much does kinetic energy produce?
The kinetic energy of an object of mass M kg moving at velocity V meters/sec is 1/2 x M x V2 Joules
When is kentic energy the greatest?
Kinetic energy depends on an object's mass, as well as on its speed. Since an object's mass usually doesn't change much, the kinetic energy will be greatest when the object moves fastest.

What does kinetic energy do?
Kinetic energy tells you how much energy an object has due to motion. The faster an object is moving, the more kinetic energy it has. Moving objects also have more kinetic energy if they have more mass, because it takes more work to get them moving. The formula for kinetic energy is (1/2)mv2 where m is mass and v is velocity.

If an object's mechanical energy is equal to potential energy how much kinetic energy does the object have?
Mechanical energy is defined as the SUM of potential energy plus kinetic energy. If all of its mechanical energy is potential energy, it follows that it has no kinetic 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.

The kinetic energy of an object of mass M kg moving at velocity V meters/sec is 1/2 x M x V2 Joules
An object of mass 'm' is moving with the constant velocity 'v' how much work should be done on the object to bring it to rest?
An object with mass 'm' moving with velocity 'V' has kinetic energy of [ 1/2 m V2 ] .In order to bring it to rest, its velocity has to be reduced to zero, and in order toaccomplish that, the kinetic energy has to be drained off and sent somewhere else.An external force has to absorb energy from the object, i.e. do negative work on it,equal to its kinetic energy, or- 1/2 m V2
When is kentic energy the greatest?
Kinetic energy depends on an object's mass, as well as on its speed. Since an object's mass usually doesn't change much, the kinetic energy will be greatest when the object moves fastest.
If an objects mechanical energy is equal to its potential energy how much kinetic energy does the object have?
Mechanical energy is defined as the SUM of potential energy plus kinetic energy. If all of its mechanical energy is potential energy, it follows that it has no kinetic energy.
When does kinetic energy increase?
The kinetic energy (Ek) of a moving object will increase if it's mass (m) or velocity (v) increases.The equation for calculating kinetic energy in Newtonian mechanics is shown below.Ek = 1/2 m x v2Where it can be seen that variations in mass have a much smaller effect on kinetic energy than variations in velocity.
If an object's mechanical energy is equal to its potential energy how much kinetic energy does it have?
Mechanical Energy= Potential energy+ Kinetic energy, so for the mechanical energy to be equal to be potential energy, the kinetic energy must be 0.
