How many joules are there in 1 kilogram?

One kilogram (kg) of mass is equivalent to exactly 89,875,517,873,681,764 joules (according to E=mc2 with m = 1 kg and speed of light c = 299,792,458 m/s).

What is the energy equivalence of 1 gram of mass?

If 1 gram of mass is converted into energy, then to determine how much energy is involved in ergs, you just multiply 1 gram by the speed of light squared, in units of centimeters per second. Energy in ergs = 1 gram x ( 30,000,000,000.0 cm/sec) x (30,000,000,000.0 cm/sec).

How much energy does it take to lift 1 kg?

Lifting Weights: On earth it takes about 10 Newton-meters (N-m) of energy to raise a 1 kilogram mass to a height of 1 meter. Since 1 N-m equals 1 Joule, that’s 10 Joules. If it takes 1 second to lift the weight 1 meter, than you have converted 10 Joules of energy to potential energy in one second.

How do you convert mass to joules?

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.

What is the amount of energy produced when 1 g mass is converted into energy?

Physical Science So, using this formulae, Energy released= [{1*10^(-3)} * (3* 10^8)^2] joules = 9*10^13 joules = 90 TJ.

How much energy is in a gram?

Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram.

How many joules does it take to lift 1 kg?

Unit of energy is Joules (J) or Kg m^2 /s^2. Therefore the energy required to lift the object of mass 1kg to the height 1 m is 9.8 Jules.

How much energy does it take to lift 1 ton?

Assuming you mean a tonne – ie a metric tonne, 1000kg – the energy required to lift one tonne to a height of one meter is given by the equation ‘mgh’ – mass times the acceleration due to gravity times the height, so that’s 1000 * 9.8 * 1, or 9,800 Joules.
