Dear Wiki Questioner,
To calculate the kinetic energy of an object, we use the following equation:
KE=(1/2) m v^2
Where KE is the object's kinetic energy in Joules
m is the object's mass in kilograms
and v is the object's velocity in meters per second
So for your question, we first convert the mass of the bullet into kilograms so we can use it in our equation:
25g (1 kg/ 1000 g) = .025 kg
The mass of the bullet is .025 kilograms!
Now we plug the numbers into the equation and solve:
KE = (1/2) .025 kg (500 m/s)^2 = 3125 kg m^2/s^2 = 3125 J
So the kinetic energy of your bullet is 3125 Joules
To determine the velocity of the bullet, we can use the formula for kinetic energy: KE = 0.5 * m * v^2, where KE is the kinetic energy, m is the mass, and v is the velocity. Given that the kinetic energy is 3150 joules and the mass is 60 grams (which is 0.06 kg), we can rearrange the formula to solve for v. Plugging in the values, we get 3150 = 0.5 * 0.06 * v^2. Solving for v, we find that the velocity of the bullet is approximately 250 meters per second.
The kinetic energy of the person can be calculated using the formula: KE = 0.5 * mass * velocity^2. First convert the mass to kilograms (1 gram = 0.001 kg), then plug in the values to find the kinetic energy. The result will be in Joules.

When a pendulum is released close to someone's nose, the energy transfer from the pendulum to the nose is mainly in the form of kinetic energy. As the pendulum swings down towards the nose, its potential energy is converted into kinetic energy, which can cause harm upon impact if not stopped. The amount of energy transferred will depend on the mass and velocity of the pendulum.
If all of the potential energy is transferred to the arrow's motion as kinetic energy,then when the shot is complete and before any effect of air resistance has kicked in,its kinetic energy is 50 joules.KE = (mass) x (speed)250 = (.01) x V2V = sqrt(5000) = 70.711 meters per second, as it leaves the bow.Oops! Please excuse us. We thought you were going for the arrow's speed as it leftthe bow. Now we notice that you only wanted its kinetic energy. That's 50 joules,and it doesn't make any difference what its mass is. That was a 10-gram red herring.
Conversions first. 124 grains (1 gram/15.43 grains)(1 kilogram/1000 grams) = 0.008036 kg ==============

The molecules in a gram of steam have more kinetic energy than the molecules in a gram of ice. This is because steam has a higher temperature and its molecules are moving faster compared to the slower-moving molecules in ice.

KE = 1/2 M V2 = (0.5) x (0.0605) x (273)2 = 2,254.5 joules (rounded)That's considerable KE ! It's roughly the same as a 220-pound man moving at 15 mph.That helps me understand how a bullet can knock a big person down, not to mentiondoing some damage to his infrastructure..
