Physlet Simulations for First-Semester Physics
- When a force is applied for particular length of time, it's useful to think about impulse, the product of the force and the time it is applied.
-- Check out the Physlets simulation Physlet Simulations for First-Semester Physics (it's the first one listed under "Momentum").
-- The airbag works by applying a small force for a relatively long time (the opposite of what happens in a head-on crash without the airbag).
-- Ion drive works by applying a tiny force over a very long time.
