Question

question ①
an object in mechanical equilibrium is an object ________.
select all that apply
□ moving with constant velocity
□ at rest
□ having no changes in velocity
□ moving in a circle
□ speeding up
□ changing direction

Explanation:

Mechanical equilibrium means the net force on an object is zero, so its acceleration is zero. This means the object's velocity does not change: it can be stationary (at rest) or moving at a constant velocity (no change in speed or direction). Moving in a circle, speeding up, or changing direction all involve acceleration (changing velocity), so these do not fit mechanical equilibrium.

Answer:

• moving with constant velocity
• at rest
• having no changes in velocity
