An estimate is a rough educated guess at the value of a physical quantity based on prior experience and sound physical reasoning. Some strategies that may help when making an estimate are as follows: ...An estimate is a rough educated guess at the value of a physical quantity based on prior experience and sound physical reasoning. Some strategies that may help when making an estimate are as follows: 1) Get big lengths from smaller lengths. 2) Get areas and volumes from lengths. 3) Get masses from volumes and densities. 4) If all else fails, bound it. One “sig. fig.” is fine. 5) Ask yourself: Does this make any sense?
