Suppose you have a nearly empty jar of salsa that you want to pour into a bowl. Of course you will turn the jar upside down – but sometimes this is not enough to get the salsa out of the jar. Usually you will not only turn the jar over but also shake it up and down. Use Newton’s Laws to explain why shaking helps the salsa come out of the jar.
