Kinetic energy is possessed by moving bodies so that is easy. Potential energy comes in different forms - gravitational for instance due to height above the surface of the earth. Other forms like chemical, nuclear, elastic, are not so obvious, you need to know the properties of the material before it can be estimated.

How does the mass of an object affect its kinetic energy?
Mass is directly proportional to the amount of kinetic energy an object posses according to this formula. Ek= 1/2mv2. There are two factors, which can alter the amount of kinetic energy. 1. The velocity of an object, how much momentum does the object carry. 2. The mass, small or big. if an object with mass of 5kg travelling at 7m/s has an overall kinetic energy of 123j. directly if an object weighing twice to have the same kinetic energy, its mass should be 4.959kg. you can get this using v2=Ek/0.5m.
Can an object have kinetic energy and potential energy at the same time?
a body cannot have both kinetic and potential energy at the same time because, a moving body can only possess kinetic energy at a time, but potential energy is one possessed by a body with respect to its possition.
How is kinetic energy calcuated?
For an object with mass m travelling at speed v (assuming it is well below the speed of light), the kinetic energy is given by the mass multiplied by the square of the speed, divided by two. So: Kinetic energy = m v2 / 2 The potential energy is a little more complicated - this answer assumes you mean gravitational energy. The magnitude of the gravitational potential energy between any two objects is given by the product of their masses multiplied by the gravitational constant, divided by the distance between their centres of mass. Gravity is always an attractive force, so we give it a negative sign to indicate this. So: Potential energy = - G m1 m2 / r where G = 6.7 x 10-11 m3 kg-1 s-2 m1 and m2 are the two masses in kilograms (say the mass of the Earth and the mass of the Sun) r = the distance in metres between their centres of mass If you need the potential energy in a much simpler example, say by raising an object of mass m by a height h vertically, the solution is much easier. The potential energy then is given by: Potential energy gained = m g h i.e. mass (kg) x gravitational field strength (N/kg) x height (m) On Earth, the gravitational field strength is about 9.8 N/kg Kinetic Energy=1/2 times mass times velocity squared
What accounts for the aircraft carrier having a greater kinetic energy than the falling nickel?
The aircraft carrier has a greater kinetic energy because it is so much more massive. Kinetic energy = (1/2)mv2, where m is mass and v is velocity.
Where does a skater have the most kinetic energy?
At rest at top of slope, it is all potential energy(mass * g * vertical distance to bottom of slope). Ignoring friction losses, this will translate to all kinetic energy at the bottom. kinetic energy = 0.5 * mass * velocity squaredexample:mass of sled + rider = 100 kgg = 9.82 ((m/s)/s) acceleration due to gravityvertical distance = 20 metresso:potential energy at slope top = 100 * 9.82 * 20 = 19 640 joulesso:kinetic energy at bottom = 19 640 joulesso :19 640 = 0.5 * 100 * velocity ^2so:velocity = square root (19 640 / (0.5 * 100))velocity = 19.82 metres / sec
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 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.
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.
How do you determone how much kinetic energy an object has?
by finding it's mass and speed
What 2 factors determine how much kinetic energy an object has?
Mass and Velocity
How much kinetic energy is in a solid?

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).
