Question: 1 / 400

What is the effect of an unbalanced force on an object?

The object will remain at rest.

The object will accelerate in the direction of the net force.

An unbalanced force acting on an object results in a net force that changes the object's state of motion. According to Newton's second law of motion, when a net force is applied to an object, it causes the object to accelerate in the direction of that net force. This acceleration can lead to a change in the object’s velocity, which may involve increasing speed, decreasing speed, or changing direction.

When a force is balanced, such as when multiple forces acting on an object cancel each other out, the object does not accelerate and either remains at rest or continues moving at a constant velocity. However, an unbalanced force disrupts this equilibrium, clearly affecting the object’s motion and causing it to respond accordingly—this is fundamental to understanding dynamics in physics.
