The Kinetic Energy from Change in Velocity calculator computes the kinetic energy (KE) required to change the velocity of a object of a certain mass (m) from an initial velocity (V1) to a final velocity (V2).
INSTRUCTIONS: Choose the preferred units and enter the following:
- (m) Mass of Object
- (V1) Initial Velocity of Object
- (V2) Final Velocity of Object
Kinetic Energy (KE): The calculator returns the energy in joules. However this can be automatically converted to other energy units via the pull-down menu.
The Math / Science
This is a formula for Kinetic Energy (KE). Kinetic Energy is a scalar quantity. This equation uses as inputs the mass (`m`) and values for magnitude of its velocity (`V`).
Kinetic energy can be assigned a value knowing only the mass of the body and the magnitude of its instantaneous velocity relative to a specified coordinate frame, without regard for how this velocity was attained. Hence, kinetic energy is a property of the body. Since kinetic energy is associated with the body as a whole, it is an extensive property.
Energy Calculators
- Kinetic Energy: `KE= 1/2 *m * v^2`
- Kinetic Energy (change of velocity): `KE = 1/2*m*(V_1-V_2)^2`
- Relativistic Kinetic Energy: `E_K = (m*c^2)/sqrt(1 - v^2"/"c^2") - m*c^2`
- Potential Energy: `U(y) = m*g*y`
- Potential Energy of Gravity (two bodies): `U(G) = - (G*m1*m2)/r`
- Nuclear Binding Energy: `E = m*c^2`
- Quantum Energy (Planck's Equation): `E = h*f`
- Energy of a Particle in a Box: `E_n=(n^2h^2)/(8mL^2)`
- Molecular Kinetic Energy: `KE = 3/2 * k_B *T`
- Electrostatic Potential Energy: `E_(el) = k_e * (Q_1*Q_2)/d`
- Photon Energy from Wavelength: `E = (h*c)/lambda`
- Heat Energy to Change Material Temperature: `Q = C * m *DeltaT`
