Balanced and Unbalanced Forces Flashcard

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, resulting in a change in motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, there is no motion or change in the state of the object.

Front

What happens when forces are unbalanced?

Back

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

Front

Define force in physics.

Back

A force is a push or pull exerted on an object that can cause it to accelerate.

Front

What is the net force?

Back

The net force is the vector sum of all the forces acting on an object.

Front

How can you determine if forces are balanced or unbalanced?

Back

If the net force is zero, the forces are balanced; if the net force is not zero, the forces are unbalanced.

Front

What is an example of balanced forces in everyday life?

Back

An example of balanced forces is a book resting on a table, where the gravitational force is balanced by the normal force from the table.

Front

What is an example of unbalanced forces in everyday life?

Back

An example of unbalanced forces is a soccer ball being kicked, where the force of the kick is greater than the opposing forces.

Front

What role does friction play in balanced and unbalanced forces?

Back

Friction is a force that opposes motion; it can contribute to balanced forces when it equals the applied force, or to unbalanced forces when it is less than the applied force.
