You're absolutely right! The force needed to accelerate an object is calculated using Newton's Second Law of Motion:

Force (F) = Mass (m) × Acceleration (a)

Here's how to apply it to your example:

* Mass (m): 1000 kg

* Acceleration (a): 3 m/s²

Force (F) = 1000 kg × 3 m/s² = 3000 Newtons (N)

Therefore, you would need a force of 3000 Newtons to accelerate the 1000 kg car at a rate of 3 meters per second squared.
