Forces and Newton`s Laws
... Does the amount of acceleration depend on the object or just the amount of force? Acceleration times time gives final velocity which (along with angle) determines how far a projectile travels. If you were to throw a gallon milk and a can of soda (with the same force), which would travel farther? ...
