In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

Amperes cannot be converted to joules, because they are two different units. One is current (molasses flow) and the other is work (bicycling). However, there is a relationship between them. To find it, you must know the amperage, the voltage, and the wattage (number of joules per second).

The joule ( jawl, jool; symbol: J) is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force's motion through a distance of one metre (1 newton metre or N⋅m).

To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in kilograms), c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius), and ΔT is the change in ...

J stands for joules and Hz stands for hertzs. The formula used in joules to hertzs conversion is 1 Joule = 1.509190311676E+33 Hertz. In other words, 1 joule is 1.509190311676E+33 times bigger than a hertz.

The amount of kinetic energy gained depends on the mass and the speed of the object. Find the kinetic energy of a 10 kg mass which is moving at 20 m/s. Ek = ½ x 10 kg x (20 m/s)2 = 2000 Joules When moving objects be stopped, all their kinetic energy must be transformed into another form of energy.

1 unit of electricity is equal to 3.6×10^6 joules or 3600000 joules. Joule: One joule is defined as the amount of energy used when a force of one newton is applied over a displacement of one meter.

The initial kinetic energy of m1 plus m2 is 3/2 Joule. The difference is 1/6th of a Joule which is lost in heat of the collision.

Energy = Power x Time Power = V x I = 200 x 10 = 2000 watts Energy = 2000 x 60 = 120,000 Joules or 120 kJ.

Where W is the work done calculated in Joules and Q is the heat change calculated in calories. J normally has a unit of J/cal. But in SI units calorie is converted to Joule, changing the magnitude too for J. Hence in SI system J becomes 1/4.18 times its previous value with dimensions Joule/Joule(no units hence).

If you're looking to find how much energy is in one gram of a given substance with mass, disregarding some math, just take mass and multiply it by c^2. So m = 1g = 0.001kg, E = mc^2 = (0.001kg)(299792458m/s)^2 = 8.987551787E13kgm^2/s^2 = 8.99 x 10 ^ 13 joules.

Substituting h with its value in J⋅s and f with its value in hertz gives the photon energy in joules. Therefore, the photon energy at 1 Hz frequency is 6.62606957 × 10−34 joules or 4.135667516 × 10−15 eV.

Rotational kinetic energy can be expressed as: Erotational=12Iω2 E rotational = 1 2 I ω 2 where ω is the angular velocity and I is the moment of inertia around the axis of rotation. The mechanical work applied during rotation is the torque times the rotation angle: W=τθ W = τ θ .
