Balanced and Unbalanced Forces

Front

What are balanced forces?

Back

Balanced forces are forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Unbalanced forces are forces that are not equal in size or opposite in direction, causing a change in motion.

Front

Example of balanced forces in everyday life?

Back

A book resting on a table is an example of balanced forces; the weight of the book is balanced by the upward force of the table.

Front

Example of unbalanced forces in everyday life?

Back

A car accelerating is an example of unbalanced forces; the engine's force is greater than the friction opposing it.

Front

What happens when forces are balanced?

Back

When forces are balanced, the object remains at rest or continues to move at a constant speed.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the object will accelerate in the direction of the net force.

Front

How can you tell if forces are balanced or unbalanced?

Back

You can tell by observing the motion of the object; if it is at rest or moving at a constant speed, the forces are balanced.

Front

What is the net force?

Back

The net force is the total force acting on an object, calculated by combining all individual forces acting on it.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass affect inertia?

Back

The greater the mass of an object, the greater its inertia, meaning it will be harder to change its motion.
