To increase acceleration (a), use Newton’s 2nd law: a = Fnet / m. So:
- Increase the force that the engine provides — yes (larger F → larger a).
- Decrease the mass of the car — yes (smaller m → larger a).
Do not:
- Decrease the force the engine provides — no.
- Increase the mass of the car — no.
Changing the top velocity does not directly change instantaneous acceleration. (In practice, changing gearing or engine tuning to raise top speed can trade off with acceleration, but top speed itself is not a direct way to increase acceleration.)
