Examples of Balanced Forces:
A Book on a Table:
When you put a book on a table, gravity pulls it down with a force of about 9.8 newtons.
But the table pushes back with an equal force.
These forces balance each other out.
A Person Standing Still:
When someone stands still, gravity pulls them down just like it does with the book.
But the ground pushes up with the same force.
Again, these forces balance each other out.
Examples of Unbalanced Forces:
A Car Accelerating:
Imagine a car that wants to speed up.
The engine pushes it forward with a force of 2000 newtons.
But there is also friction that slows it down, which is about 1500 newtons.
The leftover force makes it move forward with a net force of 500 newtons.
A Soccer Ball Being Kicked:
When you kick a soccer ball, the force from your kick is much stronger than any opposing forces.
This unbalanced force sends the ball flying, often reaching speeds of 25 meters per second.
