# How to calculate loss of kinetic energy in a collision?

In order to calculate the loss of kinetic energy in a collision, you will need to know the following information: the mass of the object, the velocity of the object before the collision, the velocity of the object after the collision, and the angle of the collision. With this information, you can use the following equation:

KE = 1/2 * m * v^2

where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.

For example, let’s say that you have a mass of 10 kg and a velocity of 5 m/s. If you collide with an object at an angle of 45 degrees, your velocity after the collision will be 2.5 m/s. Using the equation above, you can calculate that the loss of kinetic energy in the collision will be:

KE = 1/2 * 10 kg * (5 m/s)^2

KE = 1/2 * 10 kg * 25 m^2/s^2

KE = 125 kg * m^2/s^2

KE = 62.5 kg * m^2/s^2

### Q: How do you find kinetic energy loss in a collision?

A: There is no simple answer to this question, as the amount of kinetic energy lost in a collision depends on a number of factors, including the mass and velocity of the objects involved, the angle at which they collide, and the type of materials they are made of. However, some basic principles can be used to estimate the amount of kinetic energy lost in a collision. For example, collisions in which the objects involved are of similar mass and velocity and collide head-on tend to result in the greatest amount of kinetic energy loss.

### Q: What is the loss of kinetic energy after collision?

A: The loss of kinetic energy after a collision is given by the equation:

loss of KE = 1/2 mv^2
