Question

An object is said to be in equilibrium if ___.

• A. it is moving at a constant speed
• B. it is moving with a constant acceleration
• C. no forces act upon it
• D. no net force acts upon it

Answer 1

The correct option is D

no net force acts upon it

An object is said to be in equilibrium if no net force acts upon it. This means all components of the forces acting on the body add up to zero. An object moving at a constant speed along a curved path has a change in direction. For changing directions, we need an unbalanced force. And hence, the object won't be in equilibrium.
