Your specific task is calculate range, max height, and flight time of a projectile. Open the page, drop your input, get the result — typically under a second.
Your goal is calculate mechanical advantage and forces in pulley systems. Same approach: paste in, get the result, move on. No account, no upload.
Both tools live in the same category, so the choice depends on the exact subtask. Projectile focuses on calculate range, max height, and flight time of a projectile; Pulley focuses on calculate mechanical advantage and forces in pulley systems. Try whichever description matches your goal more closely — they're both free.
Yes — both tools are free for unlimited personal use. The Pro plan unlocks higher limits and batch features but the core functionality stays free forever.
Absolutely. Many users chain multiple tools together — process a file with one, then feed the result into another. Nothing is uploaded, so chaining is essentially instant.
No. Both Projectile and Pulley work without signup. We only ask for an email if you decide to subscribe to a paid plan.
