Question

Which of the following describes a possible state of motion for an object in mechanical equilibrium?

Options

• Moving in a circle at a constant speed

• slowing down to a stop

• Moving with increasing speed in a straight line

• At rest or moving with a constant velocity

Answer 1

At rest or moving with a constant velocity

Explanation:

Both being at rest (zero velocity) and moving with a constant velocity mean the object has zero acceleration, satisfying the condition for equilibrium.
