When forces act on a body, they can cause the body to accelerate, decelerate, or change direction. Forces can be applied in different directions and magnitudes, and their effects on the body depend on the net force acting on it.

If multiple forces are acting on a body, they can be added together to find the net force. The net force determines the overall motion of the body according to Newton's second law, which states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Additionally, forces can be categorized as either balanced or unbalanced. Balanced forces result in no change in the motion of the body, while unbalanced forces cause the body to accelerate in the direction of the net force.

Overall, understanding the forces acting on a body is crucial in predicting and analyzing its motion and behavior.

Newton's Three Laws of Motion:

1. Inertia:
- Every object tends to remain at rest or in constant motion in a straight line unless acted upon by an external force.

2. Acceleration:
- The acceleration of an object is directly proportional to the net force acting on it, and inversely proportional to its mass. In equation form: F = ma

3. Action-Reaction:
- For every action, there is an equal and opposite reaction. This means that when an object exerts a force on another object, the second object exerts an equal and opposite force on the first.

Application to Forces Acting on a Body:

1. Inertia:
- An object will continue moving at the same speed and in the same direction unless an external force changes its motion. For example, a ball rolling on a flat surface will continue rolling until it encounters friction or another force that slows it down.

2. Acceleration:
- The net force acting on an object determines its acceleration. If the net force is greater than zero, the object will accelerate in the direction of the net force. If the net force is zero, the object will remain at rest or continue moving with constant speed.

3. Action-Reaction:
- When an object pushes on a wall, the wall pushes back with the same force. This is why a person can push off a wall and move forward. Similarly, when an airplane flies, the air pushes against the wings with a force equal to the force the wings exert on the air. This generates lift and propels the airplane forward.
