Measurement and Error

Today we talked about standard units of measurement, why we have significant figures, and the two types of errors.

Notes: Measurement and Error

This weekend please get a lab notebook, preferably with graph paper pages.

Next week we’ll be doing little labs to get familiar with equipment. For homework, think of ways to measure the following that would reduce errors the most and write a short procedure:

• Time for a ball to fall a certain distance
• Distance a projectile travels
• mass of small objects
