Understanding the Concepts

* Force (F): The push or pull on an object. 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: F = m * a

This means the force acting on an object is equal to its mass multiplied by its acceleration.

Calculation

1. Rearrange the formula to solve for acceleration:

a = F / m

2. Plug in the values:

a = 450 N / 30 kg

3. Calculate the acceleration:

a = 15 m/s²

Answer: A 450N force acting on a 30-kg object will result in an acceleration of 15 m/s².
