Which of these physical quantities varies as an object changes its velocity?
A. pressure
B. mass
C. weight
D. momentum
Answer (2)
The physical quantity that varies as an object changes its velocity is momentum, calculated as the product of mass and velocity. Other options like pressure, mass, and weight do not directly change with velocity. Thus, momentum is the correct answer to the question. ;
The physical quantity that varies as an object changes its velocity is momentum. Momentum is calculated as the product of mass and velocity, and it changes whenever the velocity changes. Therefore, the correct answer is D. momentum.
