You can derive it from accelerating an object to a certain speed. Assume constant acceleration (and therefore constant force), and calculate how much work (force x distance) you need to get the object to a specific speed.

What form of energy does a cross bolt hitting a target?

Kinetic energy equal to half the mass times the velocity-squared.


How is kinetic energy defined?

Kinetic energy is the energy an object possesses due to its motion. It is calculated as one-half of an object's mass multiplied by its velocity squared (KE = 0.5 * m * v^2). The faster an object is moving or the more massive it is, the greater its kinetic energy.


How do the mass and speed of an object affect the energy?

Kinetic energy is the mass times one half the velocity squared. KE = ½mv².


How do the mass and speed of an objects affect the kinetic energy?

You know that mass equals energy but how does energy equal mass?

E = mass x velocity of light to the 2nd power (or squared) or if you use mathematical notation. E=mc2


What is the kinetic energy of mass of 30 kilograms that moves with a velocity of 15ms?

Potential Energy equals One Half Mass times Velocity squared. 30kg X 15m/sec X15m/sec =6750 Joules


Is mass times acceleration equals velocity squared dimensionally correct?

No. Fortunately, that equation doesn't appear anywhere in Physics. [mass] times [acceleration] has the dimensions [mass] x [length/time2], and that's exactly [force] which makes everything beautiful.


What is wind-energy?

It is the kinetic energy in the wind, which is half the mass times the velocity-squared, summed up for every small element of air in the wind.


How do you calculate mass when given joules and velocity?

To calculate mass when given joules and velocity, you can use the formula for kinetic energy: KE = 0.5 * m * v^2, where KE is the energy in joules, m is the mass, and v is the velocity. Rearrange the formula to solve for mass: m = 2 * KE / v^2. Plug in the values for energy and velocity to find the mass.


How do you calculate impact energy of a flying object?

Kinetic Energy= 1/2 m vv ( v squared,I don't know how to do exponentials on my computer). or one half mass times velocity squared.


What is momentum divided by velocity?

Momentum = mass x velocity. If you divide out the velocity you get mass.


Does mass and velocity equal force?

No, mass and velocity do not equal force. Force is the product of mass and acceleration, not velocity. The equation for force is F = ma, where F is the force, m is the mass, and a is the acceleration.
