How to calculate , acceleration, force, momentum and impulse??? I'm supposed to be able to calculate all of these things: velocity, acceleration, force, momentum and impulse. However, the physics course I'm taking explains it horribly! I think the formulas are: distance over time= velocity, change in velocity over change in time= accleration, but i don't know if those are right and can't find the ones for force, momentum and implse. Please help!
