If the first object is just sitting there and not moving,
then it has zero kinetic energy.

Is anything that lifted off the ground has potential energy?
True. It has "potential energy", in that gravity could be used to convert that "potential" energy into actual kinetic energy.
What happens to the kinetic energy of the snowball as it rolls across the lawn and gaines mass?
Assuming the lawn is level, the kinetic energy is lost by: 1) Friction 2) The growth of the snowball, as snow sticks to it, its radius increases and this mean that the new snow has to be lifted to the top (from the base) along its direction of role. This converts the kinetic energy into potential energy and slows the snowball.
A 5kg object is being lifted to a height of 8 meters and is dropped what is the kinetic energy of the object at 2 m?
After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy. The potential energy (for the 6 meters) is mgh = (5 kg)(9.82 m/s2)(6 m) = 294.6 J, so that is also the kinetic energy, since potential energy has been converted to kinetic energy.After falling 6 meters, potential energy corresponding to those 6 meters will be converted to kinetic energy.

Is mechanical kinetic energy or potential energy?
Potential energy is the energy that can be released, but has not been released yet. Ex. Sitting at the top of a slide is potential energy. You will eventually have to go down. Kinetic energy is the energy that is being released at any moment. Ex. As you slide down the slide kinetic energy is released.
Does fire have Kinetic or potential energy?
A blazing bonfire is the release of chemical energy.Kinetic energy is that energy that is part of a body because of its motion.Potential energy is that energy that is part of a body because of its position in a gravity field. kinetic and potential energy can interchange.However the energy in a bonfire is trapped radiation energy (sunlight) stored chemically in the substance of the wood and released by a chemical reaction.
What type of energy does a rock have when it's lifted into the air?
Kinetic energy
What type of energy is present in a barbell lifted or a shot-pull being thrown?
kinetic energy being enacted. this energy is giving rise to potential energy too, as the item is being lifted into the air. When an item is lifted, it is given potential energy, as this potential energy is what fuels its future descent. So, when moved, kinetic energy is both moving the object, and storing potential energy for future use.

True. It has "potential energy", in that gravity could be used to convert that "potential" energy into actual kinetic energy.
What factors are responsible for kinetic energy and potential energy?
Potential Energy is converted to Kinetic Energy when, for example, an object with mass m kilograms falls from a height of h metres. The mass increases its velocity at a rate equal to the earth's constant gravitational acceleration, g metres per second per second: Ep=mghAfter falling from this height, the Potential Energy will have been completely converted to Kinetic Energy, and will be moving at a velocity of v metres per second. You can then calculate the Kinetic Energy: Ek=1/2mv2So we say that energy is stored as Potential Energy when a mass is lifted up - for example, a quantity of water in a Hydroelectric Power Station is raised vertically from one storage dam to another, higher up.

When jack and Jill fetch the the pail of water what kind of energy was that?
When Jack and Jill fetch the pail of water, it involves potential energy as the water is lifted against gravity. This potential energy is converted to kinetic energy as the pail is moved horizontally.
How does the average kinetic energy of the helium atoms in a balloon change as the helium gas is heated?
the theaory of gravity when lifted by a hot air substance is qiute simple if you think about it
When in a roller coaster ride does potential energy become kenetic energy?
Potential energy becomes kinetic energy when the car begins its downward descent from the top of one of the rollercoaster's peaks. It accumlates potential energy as it is lifted to the first and highest peak. It regains some of its lost potential energy each time it re-ascends one of the lower peaks, then loses potential and gains kinetic energy as it drops again.
What energy does a weight gain if it is lifted?
It's probably kinetic because you have to move your arms up and down.
A 0.5kg basketball is lifted 5m and thrown straight ahead with a speed of 2 ms What is the Kinetic Energy of the basketball?
At the time of the throw: Kinetic energy = 0.5*mass*(speed)^2 = 0.5*0.5*4 = 1J. There is also the potential energy at the time of the throw. If you want to know the kinetic energy at the time the ball hits the ground, that term must be added: Potential energy (with respect to the ground) at the time of throw = mass*gravity*height = 0.5*9.8*0.5 = 2.45 J.
