Balanced & Unbalanced Forces

Front

What is a balanced force?

Back

A balanced force occurs when two or more forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the forces acting on an object are not equal, causing the object to accelerate or change its motion.

Example of balanced forces in everyday life?

Back

A book resting on a shelf is an example of balanced forces, as the force of gravity pulling it down is balanced by the support force from the shelf.

Front

Example of unbalanced forces in everyday life?

Back

A car accelerating around a mountain curve is an example of unbalanced forces, as the engine force is greater than the frictional force.

Front

What happens to an object when unbalanced forces act on it?

Back

When unbalanced forces act on an object, it will accelerate in the direction of the net force.

Front

What is the net force?

Back

The net force is the overall force acting on an object after all the individual forces are combined.

Front

How do balanced forces affect motion?

Back

Balanced forces do not change the motion of an object; it will either remain at rest or continue moving at a constant speed.

Front

How do unbalanced forces affect motion?

Back

Unbalanced forces cause an object to start moving, stop moving, or change direction.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is directly related to mass.

Front

What is an example of inertia?

Back

A passenger lurching forward in a car when it suddenly stops is an example of inertia.
