To answer the question, we will define the following measures using appropriate equations :
A) Weight = Mass × the gravitational acceleration.
This gives force.
B) Change of linear momentum with respect to time = mass multiplied with change in velocity with respect to time
Change in velocity with respect to time is known as acceleration.
Force = mass × Acceleration
C) Product of mass and acceleration = Force.
D) Work done per unit time = Energy used per second and it is given in joules.
The answer is thus D
