kinetic energy
When an object falls down, potential energy is converted to kinetic energy.
potential because it is storing its energy
weight and mass
Ofcourse, actually, you have to have mass in order to calculate kinetic energy. Kinetic Energy = 0.5*m*v^2 Where m is the mass. Where v is the velocity. Mass is directly proportional to the kinetic energy, the more the mass, the more the kinetic energy.
Mass and velocity (weight and speed)
Kinetic energy is the energy of motion. The amount of kinetic energy an object has depends on the mass of the object and the speed of the object. The equation is: K= (1/2)mv^2, where K=kinetic energy, m=mass, and v=speed of the object.
at the top of the ramp the toy has a certain amount of potential energy. The amount of this energy depends on the height of the ramp and the weight of the toy. (The toy's weight is dependent on its mass and the force of gravity.) As the toy rolls down the ramp this potential energy is converted to two other types of energy: Kinetic energy and heat energy. The amount of heat energy depends on friction and air resistance. The lower the total resistance the more kinetic energy, and the more speed, the toy has at the bottom of the ramp.
Not weight - mass. On Earth the two are proportional, but it is better not to confuse the two.

kinetic energy. The formula for kinetic energy is 1/2 mass (weight) x velocity (speed) squared.
weight and mass
Blowing wind has kinetic energy. This can be transformed into electrical energy using a turbine to transform the wind into rotational kinetic energy and a generator or alternator to convert the rotational kinetic energy to electrical energy. Water above a dam has potential energy from gravity and also from the weight of the water around it. Once it is moving or flowing down through the pipes it then has kinetic energy.

Weight and height. The potential energy of an object is its weight times its height. The potential energy is turned into kinetic energy as the object is dropped. Potential energy is weight times height, kinetic energy is one half mass times velocity-squared. Mgh = ½ M V^2 To reach a speed of 10 m/s this equation can be solved to show that the object must be dropped through a height of 5.1 metres.
