Force and Mass Relationship

Force (F) is defined as the product of mass (m) and acceleration (a) according to Newton's second law of motion. Mathematically, it can be represented as:

F = m * a

In this case, the force applied on the body is given as 4N and the mass of the body is 20kg. We need to find the acceleration of the body.

Given:
Force (F) = 4N
Mass (m) = 20kg

Calculating Acceleration:

To find the acceleration, we rearrange the formula for force:

F = m * a

a = F / m

Substituting the given values:

a = 4N / 20kg

a = 0.2 m/s^2

Therefore, the acceleration of the body is 0.2 m/s^2.

Explanation:

When a force is applied to an object, it causes the object to accelerate. Acceleration is the rate at which the velocity of an object changes with time. In simple terms, it determines how quickly the object speeds up or slows down.

In this case, a force of 4N is being applied to a body with a mass of 20kg. The relationship between force, mass, and acceleration is described by Newton's second law. According to this law, the force acting on an object is directly proportional to the mass of the object and the acceleration it experiences.

By rearranging the formula for force, we can calculate the acceleration. Dividing the given force (4N) by the mass of the body (20kg), we find that the acceleration is 0.2 m/s^2.

This means that when a force of 4N is applied to the body, it will accelerate at a rate of 0.2 meters per second squared.
