Complete the following statement: The term net force most accurately describes:
a) quantity that causes displacement
b) quantity that keeps the object moving
c) the mass of the object
d) the quantity that changes the velocity of an object
c) is not the right choice. I believe that answer is a) is this correct?
The answer is (d). The quantity that change the velocity of an object.
Net force could be zero, and displacement increasing (as in something in constant velocity).
Relook at d. Netforce=mass*acceleration
No, the correct answer is d) the quantity that changes the velocity of an object.
To understand why the correct answer is d), let's first define what net force means. Net force, in physics, refers to the overall force acting on an object. It takes into account all the individual forces acting upon an object, accounting for both the magnitude and direction of each force.
When multiple forces are acting on an object, they can either cancel each other out or add together to produce a net force. The net force determines the object's acceleration, or in simpler terms, how its velocity changes.
So, in other words, net force does not cause displacement (a); instead, it is responsible for changing an object's velocity. While it is true that net force can keep an object moving (b), it is more accurate to say that it changes an object's velocity rather than solely sustaining the object's motion. Lastly, net force is not directly related to an object's mass (c), as force and mass are separate physical quantities.
Therefore, the correct answer is d) the quantity that changes the velocity of an object.
