Question

What are the unequal and opposite forces acting on a body, which change its state of rest or uniform motion called?

Answer 1

Hint:In physics, a force is any influence that, when unopposed, causes an object to change its velocity. A force can cause a mass item to change its velocity (which includes starting to move from a standstill), i.e. accelerate. Intuitively, force may be characterised as a push or a pull. A force is a vector quantity since it has both magnitude and direction. The SI unit of Newton is used to measure it (N). The letter F is used to signify force.

Complete step-by-step solution:
Unbalanced force is a force that occurs when two forces acting in opposite directions on a body are not equal in magnitude and size. A body changes its position in an imbalanced force, i.e., we may see a moving item alter its direction, either increasing or reducing its speed, and a body at rest begins to move, and vice versa. Unbalanced forces are unequal and opposing forces operating on a body to modify its condition of rest or uniform motion. Practically everything that moves is the consequence of uneven forces acting on it. If you kick a football and it bounces about, it's because it's being pushed around by uneven forces. Unbalanced forces can affect an object's motion in two ways. An item at rest will move if it is subjected to uneven forces. The net force on the item is larger than zero in both of the previous cases. Unbalanced forces caused motion to alter (acceleration), and the forces' recipients - the piano and the rope - moved. To get a non moving item to move, unbalanced forces are required. Second, when unbalanced forces are applied to a moving object, the object's velocity changes. Remember that a change in velocity might refer to a change in speed, direction, or both.

Note:This is what occurs when the forces acting on an item are imbalanced. The resulting force causes a stationary item to move in the direction of the force. In the direction of the resulting force, a moving item changes speed and/or direction
