Initial kinetic energy KE = 1/2 m1v12 + 1/2 m2v22 = joules. The following calculation expects you to enter a final velocity for mass m1 and then it calculates the final velocity of the other mass required to conserve momentum and calculates the kinetic energy either gained or lost to make possible such a collision.

The total momentum of the system is the same after the collision as before it as shown by the equation initial momentum = final momentum (where final momentum is the sum of all momentums present in the system). This principle is similar to the law of conservation of energy.

Gravitational potential energy changes into kinetic energy. The equation for gravitational potential energy is GPE = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 on Earth), and h is the height above the ground in meters.

This velocity calculator uses the equation that the final velocity of an object is equal to its initial velocity added to its acceleration multiplied by time of travel. ... This calculator can be used to find initial velocity, final velocity, acceleration, or time as long as three of the variables are known.

The formula for mechanical energy is mechanical energy = kinetic energy + potential energy. Mechanical energy, mechanical energy is the energy due to the position or movement of an object okay. And ther are 2 big forms of mechanical energy, kinetic energy and potential energy.

To calculate the magnitude of the velocity at any point in time, multiply the constant acceleration rate times the time difference and then add it to the initial velocity. As an example, if you dropped a rock off a cliff, its velocity increases by 32 feet per second, every second.

calculation of kinetic energy. To calculate the percent loss of kinetic energy, the kinetic energy after the collision was subtracted from the kinetic energy before the collision, and it was then divided by the initial kinetic energy before the impact and converted into a percentage by multiplying by 100%.

You can determine the kinetic energy the "meteor" will have at the time of impact by using the equation KE = (1/2)mv^2 where KE stands for kinetic energy in Joules, m is the mass of the "meteor" in kilograms, and v is the velocity of the "meteor" in meters per second.

The sum of the initial and final velocity is divided by 2 to find the average. The average velocity calculator uses the formula that shows the average velocity (v) equals the sum of the final velocity (v) and the initial velocity (u), divided by 2.
