Mass & Weight

LEARNING OUTCOMES:

By the end of the lesson students should be able to…

• State that mass is a measure of the quantity of matter in an object at rest relative to the observer
• State that weight is a gravitational force on an object that has mass
• Define gravitational field strength as force per unit mass; recall and use the equation g =W/m and know that this is equivalent to the acceleration of free fall
• Know that weights (and masses) may be compared using a balance
• Describe, and use the concept of, weight as the effect of a gravitational field on a mass
