What is an example of balanced forces in everyday life?

Back

An example of balanced forces is a book resting on a table; the weight of the book is balanced by the support force from the table.

What is an example of unbalanced forces in everyday life?

Back

An example of unbalanced forces is when a person pushes a shopping cart; if they push harder than the friction, the cart moves.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact.
