# Is m s2 a unit of force?

Answered by Michael Wilson

M/s^2 (metres per second squared) is not a unit of force. It is actually a unit of acceleration. The unit of force is the newton (N), which is defined as the amount of force required to accelerate a 1 kilogram mass by 1 metre per second squared.

To understand this better, let’s break it down. In physics, force is defined as the push or pull applied to an object to change its velocity. It is measured in newtons (N). Acceleration, on the other hand, is the rate at which an object changes its velocity over time. It is measured in metres per second squared (m/s^2).

The relationship between force, mass, and acceleration is given by Newton’s second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. Mathematically, it can be represented as:

F = m * a

Where F is the force, m is the mass, and a is the acceleration. From this equation, we can see that the unit of force (N) is equal to the unit of mass (kg) multiplied by the unit of acceleration (m/s^2).

So, while m/s^2 can be used to measure acceleration, it is not a unit of force. The unit of force is the newton, which is equal to 1 kg * m/s^2. It is important to distinguish between these units to accurately describe and understand different aspects of motion and forces in physics.

In practical terms, understanding the unit of force is essential in various everyday situations. For example, when lifting objects, we need to exert a certain amount of force to overcome the object’s weight and move it. This force can be measured in newtons, and knowing the relationship between force, mass, and acceleration helps us determine the required force for different tasks.

M/s^2 is not a unit of force, but rather a unit of acceleration. The unit of force is the newton, which is equal to 1 kg * m/s^2. Understanding these units and their relationships is crucial for accurately describing and analyzing forces and motion in physics.
