When an object exhibits inertia it?

Question

a) resists being set in motion
b) exhibits velocity in a specified direction
c) possesses direction and magnitude
d) responds directly to friction forces
e) resists friction and slowing down

Answer 1

Horrible question...where did you find it? All the options you give can be correct.

a. By definition inertia is the resistance of a mass to change in its velocity. But...

b. Inertia tends to keep a mass velocity traveling in a specified direction...a force is needed to change that velocity direction because of inertia.

c. Inertia, as measured by momentum (p = mv), possesses both direction and magnitude because momentum, a measure of inertia, is a vector.

d. When a force, like friction, acts on an inertial body, it can change it's momentum; so its inertia state is changed as it responds to the friction force.

e. Friction force always acts in opposition to the velocity vector of the body having inertia; so the body wants to go forward, in the direction of the velocity vector and that resists the slowing down forces of the friction.

So the real answer is that all are correct. But I suspect whoever asked the question is looking for a) since inertia is more or less when an object resists being set in motion. I say more or less because inertia is also when an object resists slowing down, changing direction, or speeding up if it is already in motion. Thus, a) is only partially correct.

Terrible question; shows a lack of precision and clear understanding of what inertia is all about.

Answer 2

Inertia is defined as an object's ability to resist changes in its movement.

Answer 3

the answer is yes...a,b,c,d,and e. any object possesses (exhibits) inertia.

Answer 4

a)
like you as regards study? high degree of inertia?
