Worked Solution & Example Answer:A constant net force acts on an object moving in a straight line - NSC Physical Sciences - Question 1 - 2021 - Paper 1
Step 1
Which ONE of the following quantities associated with the object will remain constant during the motion?
Answer
In this scenario, a constant net force acting on an object implies that the object is accelerating. Therefore, kinetic energy will change as the object speeds up and momentum will also change due to the increase in velocity. Consequently, the only quantity that will be constant is acceleration since the net force remains unchanged throughout the motion. Thus, the answer is:
C. Acceleration
