What is the speed of particle whose total energy is equal to double its rest mass energy?

This works out to be 2.828 • 10^8 m/s as the speed of the particle compared to light’s speed which is 3.00 • 10^8 m/s. This also means that the partcle will have to travel at 94.28\% of the speed of light c to have kinetic energy which is twice its mass’s rest energy !

How does the speed of a particle affect its kinetic energy?

The fast-moving particle slows down. When a particle speeds up, it has more kinetic energy. When a particle slows down, it has less kinetic energy. Energy transfers from a fast-moving particle to a slow-moving particle at the moment of impact.

What happens to the kinetic energy of an object if it is speed is double?

The change in the kinetic energy of the object as the speed changes is proportional to the square of the factor by which the speed changes. If the speed of the object becomes double, its kinetic energy changes to four times the initial kinetic energy.

Does speed or mass affect kinetic energy more?

Anytime matter is in motion it has kinetic energy. The faster an object moves, the more kinetic energy it has. The more mass an object has, the more kinetic energy it has.

What happens to the kinetic energy of a particle if a the speed V of the particle is made 2v B the mass m of the particle is made M 2?

M = Mass of object or particle , v = velocity of a moving object or particle. When speed of particle is doubled then kinetic energy becomes 4 times of the initial energy. When mass of object is made half then kinetic energy becomes half of the initial kinetic energy.

What happens to the kinetic energy if the mass is constant and the speed is tripled?

The equation KE = ½ mv² shows that the relationship between Kinetic Energy and mass is directly proportional. a)So if the mass triples then the KE triples too. The relationship between Kinetic Energy and velocity is also directly proportional but with the square of the velocity.
