Key Stage 3
Meaning
Balanced Forces are forces that are the same strength but acting in opposite directions.
About Balanced Forces
The 7N up is balanced by the 7N down. | The 4N left is balanced by the 4N right. | The 6N up is balanced by the 6N down and the 5N left is balanced by the 5N right. |
Key Stage 4
Meaning
Balanced forces are force vectors which add together to make 0N resultant force.
About Balanced Forces
- When forces on an object are balanced there is no acceleration (change speed or direction).
- Balanced forces are related to Newton's First Law of motion:
- An object in motion will tend to stay in motion and an object at rest will tend to stay at rest unless an unbalanced force acts upon it.
- If the resultant force on an object is zero, then the forces are balanced.
