## What is Newton's Second Law of Motion?

How does this law relate force, mass, and acceleration?

## Newton's Second Law of Motion Explained

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This law can be mathematically represented by the formula: F = ma, where F is the net force applied on an object, m is the mass of the object, and a is its acceleration.

When applying Newton's Second Law of Motion, it is essential to understand the relationship between force, mass, and acceleration. The law helps us quantify how an object's motion changes when a force is applied to it.

If the mass of an object is increased, its acceleration will decrease for a given amount of force applied to it. Conversely, if the force acting on an object is increased, its acceleration will increase, assuming the mass remains constant.

For example, in the scenario provided, a wagon with a mass of 24 kg experiences a net force of 5 N south. By using the formula F = ma, we can calculate the acceleration of the wagon. Substituting the values: F = 5 N and m = 24 kg, we get a = 5/24 m/s^2. Therefore, the wagon's acceleration is approximately 0.208 m/s^2 south.

Understanding Newton's Second Law of Motion is crucial in predicting and analyzing the motion of objects under the influence of forces. By utilizing this law, we can make accurate calculations and predictions regarding the behavior of objects in motion.
