Understanding the Concepts

* Force (F): A push or pull that can cause a change in motion. Measured in Newtons (N).

* Mass (m): The amount of matter in an object. Measured in kilograms (kg).

* Acceleration (a): The rate of change of velocity. Measured in meters per second squared (m/s²).

* Newton's Second Law of Motion: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, it's expressed as: F = ma

Solving the Problem

1. Identify the knowns:

* Force (F) = 1.0 N

* Mass (m) = 1.0 kg

2. Apply Newton's Second Law: F = ma

3. Rearrange the equation to solve for acceleration: a = F/m

4. Substitute the values: a = (1.0 N) / (1.0 kg)

5. Calculate: a = 1.0 m/s²

Answer: When a 1.0 N force acts on a 1.0 kg object that can move freely, the object will accelerate at a rate of 1.0 m/s².
