When forces are of equal size and opposite direction called?
Balanced forces
Balanced forces are equal in size and opposite in direction. When forces are balanced, there is no change in motion.
Is it true that forces that are equal in size but opposite in direction are called unbalanced forces?
Forces that are equal in size but opposite in direction are called balanced forces. Balanced forces do not cause a change in the motion of objects. Forces that cause a change in motion of objects are called unbalanced forces.
How are horizontal and vertical forces equal in size?
The horizontal forces are equal in size and opposite in direction. They are balanced, so the horizontal resultant force is zero. This means that there is no horizontal acceleration. The vertical forces are equal in size and opposite in direction.
How are unbalanced forces different from balanced forces?
forces that are equal in size and opposite in direction. Balanced forces do not result in any change in motion. unbalanced forces: forces applied to an object in opposite directions that are not equal in size. Unbalanced forces result in a change in motion.
When does a body exert a force on another body?
If body A exerts a force F on body B, then body B exerts an equal and opposite force −F back on body A. The mathematical expression for this is FAB = −FBA. The subscript AB indicates that A exerts a force on B, and BA indicates that B exerts a force on A. The minus sign indicates that the forces are in opposite directions.
When is the driving force greater than the resistive force?
This includes situations when the speed, the direction, or both change. For example, when a car accelerates, the driving force from the engine is greater than the resistive forces. The resultant force is not zero. The submarine above has both vertical forces and horizontal forces acting on it.
