If a particle’s speed increases by a factor of 3, by what factor does its kinetic energy change?
The factor by which the KE of a particle change if the speed of the particle increases by a factor of 3.
Answer to Problem 1CQ
Solution:
The KE increases by a factor of 9.
Explanation of Solution
Given Info:
The speed of a particle increases by a factor of 3.
Formula used:
The KE of a body of mass
Calculation:
When the speed increases by a factor of 3, the new KE is
Conclusion:
The KE of particle is directly proportional to the square of its speed.
