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.
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 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.
What 2 factors determine how much kinetic energy an object has?
Mass and Velocity
What is needed to calculate kinetic energy?
Mass of a body and its speed are needed to calculate kinetic energy. Kinetic energy of an object = mv2/2 This formula is useful only when object's speed is much less than speed of light.
What two factors determine how much kinetic energy a moving energy?
Do you mean "a moving object"? Then the answer is mass & speed.
Can an object have heat and thermal energy?
The answer is "partly". Thermal energy consists of the average kinetic energy of the particles (how much they move around, bumping into things and each other) and the average potential energy of the particles (tough to picture - how much they "shake back and forth", or oscillate, from their normal, resting position).
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).
What is kinetic energy?
Kinetic energy is the energy that an object has due to its motion or movement. For instance if a car drives into a wall the energy of its movement is what destroys the wall, That energy is kinetic energy. Note: Heat is also a form of Kinetic energy because heat is the movement (vibration energy) of atoms or molecules.
Mechanical energy is a term that is used to describe?
Mechanical energy is the sum of kinetic energy and potential energy of some object. So any object in motion, has potential to be in motion, or has both has mechanical energy. Your car in motion has kinetic energy and potential for more kinetic energy in the gasoline that it runs on. So your car has mechanical energy. Or you up on the three-meter diving board at the pool have potential for kinetic energy when you take a swan dive off that board. You have mechanical energy there. But, bottom line, pretty much any object that is either in motion or can be put into motion has a form of mechanical energy.
