Energy Formula Physics Math

1 the mass of a baby elephant is 113 kg and it walks at a constant velocity of 0 5 m sec.

Energy formula physics math. Pe m g h. For one mole the energy is 2 394 x 10 5 j. Pe 0 98 kg m 2 s 2. E k 1 2 mv 2.

It still needs to be converted from j to kj for the final answer. U frac 3 2 nrt u 23. Physics formulas and math formulas. The formula for kinetic energy states that the kinetic energy of a body is directly proportional to the velocity of a body.

At 1 m above the ground it s potential energy is. Use the kinetic energy equation. Potential energy is measured in si unit of joule. The formula of mechanical energy is.

The potential energy of an object is due to its position and kinetic energy is due to its motion. The mass m 113 kg and the velocity v 0 5 m sec. Swap sides and rearrange. E k 1 2 113 kg 0 5 m sec 2.

The internal energy of an ideal gas has one of the simplest equations. E k 1 2 113 kg 0 25. Ignoring air resistance which is small for this little drop anyway that pe gets converted into ke. Formula dilution formula electron dot structures formula heat of fusion formula heat of vaporization formula lattice energy formula limiting reactants formula mass percent formula mole fraction formula osmotic pressure formula electric.

The formula for potential energy of a system depends on the forces at work and the constituents of a system. Kinetic energy formula questions. There is also a special equation for elastic potential energy which describes the energy stored in a compressed or stretched elastic material like a spring trampoline or a bow with a nocked arrow. M e mv2 mgh.

V velocity of that object. The potential energy of an object is zero when it is in the movement and kinetic energy is zero when the object is in rest. M mass of an object. Ek 1 2mv m is the mass v is the velocity work power energy exams and solutions physics formulas work power energy cheatsheet.

Note how the value retains the correct number of significant figures. V 2 ke m now put pe into ke and we get. Ke m v 2. M v 2 ke.

All macroscopic systems outside the atomic nucleus are either governed by the electromagnetic or gravitational forces. For internal energy the equation depends on the number of moles or molecules in the closed system and its temperature in kelvins. What is the kinetic energy for the baby elephant. Pe 0 1 kg 9 8 m s 2 1 m.

V 2 2 ke m. X k is the spring constant and x is the amount of compression or streching kinetic energy.
