Understanding the Concepts

* Force (F): The 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

Newton's Second Law of Motion states: Force = Mass x Acceleration (F = m x a)

Calculation

* Mass (m) = 1000 kg

* Acceleration (a) = 3 m/s²

Force (F) = 1000 kg * 3 m/s² = 3000 N

Answer

You would need a force of 3000 Newtons to accelerate a 1000 kilogram car at a rate of 3 meters per second squared.
