Balanced and Unbalanced Forces Flashcard

Front

What is the definition of balanced forces?

Back

Two forces acting in opposite directions on an object, and they are equal in size.

Front

How can you explain balanced forces using an example?

Back

Balanced forces can be explained using the example of a book resting on a table. The force of gravity pulling the book downward is balanced by the upward force from the table, resulting in no motion.

Front

What is the definition of unbalanced forces?

Back

Forces that are not equal in size and opposite in direction.

Front

What conclusion can be made with the diagram of two people pulling on a rope?

Back

An example of balanced forces.

Front

How do balanced forces affect an object?

Back

They do not cause any change in the object's motion.

Front

What happens when unbalanced forces act on an object?

Back

The object will accelerate in the direction of the larger force.

Front

Can you give an example of unbalanced forces?

Back

A child pushing a swing; if the child pushes harder than the resistance of the swing, it will move.

Front

What is the net force when two equal forces act in opposite directions?

Back

The net force is zero, resulting in balanced forces.

Front

What is an example of balanced forces in nature?

Back

A bird hovering in the air, where the lift from its wings balances the weight of the bird.

Front

What is the effect of unbalanced forces on a stationary object?

Back

It will start to move in the direction of the unbalanced force.
