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.

∙ 14y agoTo calculate the potential energy, use the formula potential energy = mgh (mass x gravity x height). Use 9.8 for the gravity. When it falls half-way down, half of that potential energy will have been converted to 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.
Which object had more kinetic energy the one that has a mass of 2 kilograms or the one with the mass of 4 kilograms and was lifted at a rate of 3meters per second?
If the first object is just sitting there and not moving, then it has zero 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.
Do all objects have energy?
Potential energy is due to the height.And kinetic energy is due to motion.So if anything is at some height it will have potential energy and when anything is in motion it will have kinetic energy.
How are potential energy and kinetic energy different?
potential energy is any type of energy but just stored. It could be sound, light or electricity. kinetic energy could be kinetic potential energy (stored movement energy) or energy of something that is currently moving. Hope that helps.
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.

How do you calculate energy input for lifting objects by weight and height lifted?
When an object is lifted to a certain height, the mechanical energy of the person or system lifting the object gets transferred into the potential energy of the object. Thus if an object of mass/weight 'm' is lifted to a height 'h', then the potential energy possed by the object at height 'h' is given as: Potential Energy (P.E)= m*g*h, where g is acceleration due to gravity and whose value is 9.8 m/s2.
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.
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.

How do kinetic and potential energy differ?
Kinetic energy is the energy a body has because of its motion. Potential energy is stored energy inside an object that is contained.Example:stuffing stored in turkey
