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 at which an object's velocity changes (measured in meters per second squared, m/s²).

Newton's Second Law of Motion

The relationship between force, mass, and acceleration is described by Newton's Second Law of Motion:

* F = m * a

Solving for Acceleration

1. Rearrange the formula: To find acceleration (a), we need to isolate it:

* a = F / m

2. Plug in the values:

* F = 900 N

* m = 750 kg

3. Calculate:

* a = 900 N / 750 kg

* a = 1.2 m/s²

Answer: The acceleration of the 750 kg car from a force of 900 N is 1.2 m/s².
