How do you get kinetic energy?

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

You can also ask how do you find final speed after a collision?

Solving for the final velocity, v=maua+mbubma+mb v = m a u a + m b u b m a + m b . Also, how do you find final momentum? The final momentum would be the mass of both balls times the final velocity, (4+6)(vf). We can solve for vf through conservation of momentum; the sum of the initial momentum values must equal the final momentum.

Can you have negative momentum?

Momentum is a vector quantity, given by the product of an object's mass and velocity. If the velocity of the object is negative, i.e. the object is traveling in what has been chosen as the negative direction, the momentum will also be negative. Then, how do you prove an inelastic collision? If objects stick together, then a collision is perfectly inelastic. When objects don't stick together, we can figure out the type of collision by finding the initial kinetic energy and comparing it with the final kinetic energy. If the kinetic energy is the same, then the collision is elastic.
