. The kinetic energy acquired by a mass m
a mass m travelling distance d, starting from rest, under the action of a constant force is directly proportional to:
A: m
B: m0
C: √(m)
D: 1/√(m)
Best Answer
Explanation:
Work done by external forces = Change in kinetic energy
Since a particle starts from rest, its initial Kinetic Energy is 0
Therefore,K.E=FD
It is given that force is constant.
We see that Kinetic energy is independent of mass.
Final answer:
The kinetic energy acquired by a mass m travelling distance d, starting from rest, under the action of a constant force is directly proportional to m0.
Therefore, Option “B” is correct.
