Balanced and 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 in the direction of the net force.

Front

What is the effect of balanced forces on an object?

Back

Balanced forces do not change the object's motion; the object remains at rest or continues to move at a constant speed.

Front

What is the effect of unbalanced forces on an object?

Back

Unbalanced forces cause an object to accelerate, change direction, or change its state of motion.

Front

What is frictional force?

Back

Frictional force is a force that opposes the relative motion between two surfaces in contact.

Front

How does friction affect motion?

Back

Friction can slow down or stop the motion of an object, depending on the surfaces in contact and the force applied.

Front

What is an example of a balanced force in everyday life?

Back

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

Front

What is an example of an unbalanced force in everyday life?

Back

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

Front

What role does gravity play in balanced and unbalanced forces?

Back

Gravity is a force that can create both balanced and unbalanced forces, depending on whether it is countered by other forces.

Front

What happens to an object in motion when balanced forces act on it?

Back

An object in motion will continue to move at a constant velocity when balanced forces act on it.
