Q:

# What is the meaning of unbalanced force?

A:

Unbalanced force occurs when two forces acting on an object are not equal in size, causing a change in motion. Unbalanced forces cause a still object to move or moving objects to slow down or speed up, stop or change direction.

A balanced force exists when opposing forces are of equal magnitude, ultimately canceling each other out and resulting in no motion. Unbalanced forces are not equal or opposite. When two unbalanced forces are exerted in opposite directions, the net force is equal to the difference between the two forces, resulting in motion in the direction of the larger force.

Newton's first law of motion states, "Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it." An unbalanced (or unbalancing) force is another name for an external force.

Balanced forces are forces that produce no change in motion, while unbalanced forces produce some type of acceleration. With balanced forces, any forces in a given direction are exactly matched by forces in the opposite direction. With unbalanced forces, the forces in one direction are greater than those in the opposite direction, resulting in a net force that produces acceleration.

According to Education.com, the pull of gravity acts more on an object rolling down a ramp inclined at a steeper angle, hence causing it to accelerate and move faster. For Dummies explains that when objects are rolling down an inclined plane such as a ramp, a component of the force of gravity causes it to accelerate downward.

The law of inertia states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The law of inertia is sometimes referred to as Newton's first law of motion.
