GCSE Science/Balanced and unbalanced forces
Balanced and Unbalanced Forces
[edit | edit source]Resultant Force-The resultant force is the single force that, when applied to a body, produces the same effect as the combined effect of multiple forces acting on that body.
Balanced Forces- If the vector sum of all the forces acting on a body is zero.
- In such cases the acceleration of the object is zero, and its velocity remains constant.
- If the total force acting on the object is zero, the object either remains at rest or continues to move with constant velocity.
- FNet=0
Unbalanced Forces-If the net force exerted on an object is not zero, then the force acting on it is said to be unbalanced.
- Acceleration of the object is not zero and its velocity changes.
- If the total force acting on an object is not zero then such a force changes state of rest or the state of uniform motion.
- FNet≠0
