Understanding the Concepts
* Force (F): The push or pull that causes a change in an object's 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
Newton's Second Law of Motion states the relationship between force, mass, and acceleration:
* Force (F) = Mass (m) × Acceleration (a)
Solving the Problem
1. Identify the given values:
* Mass (m) = 18 kg
* Acceleration (a) = 36 m/s²
2. Apply the formula:
* Force (F) = 18 kg × 36 m/s²
3. Calculate the force:
* Force (F) = 648 N
Answer: A force of 648 Newtons is required to accelerate a body with a mass of 18 kilograms at a rate of 36 m/s².
