Final answer:
When the velocity of an object is tripled, the momentum is changed by a factor of three and the kinetic energy is changed by a factor of nine.
Step-by-step explanation:
When the velocity of an object is tripled, the momentum is changed by a factor of three and the kinetic energy is changed by a factor of nine.
Momentum is given by the product of mass and velocity, so if the velocity is tripled, the momentum will also triple. On the other hand, kinetic energy is given by the formula 1/2 mass multiplied by velocity squared, so if the velocity is tripled, the kinetic energy will be changed by a factor of (3^2) which is equal to nine.
