K_Hushii 🍁 4 years, 4 months ago

A force that does not change the state of rest or motion of an object is a balance force. So a balance force does neither make a body at rest to move nor make a body in motion to come in rest . it does not allow a body in motion to even change its direction or increases its speed too.
