Presentation transcript:

Do Now Heading: Weight vs Mass Pick up a lab from the front table Draw and Answer these questions in your journal. Two planets are initially 3 meters apart. The force between them is F = 1N. The planets are then moved 6 meters apart. What is the new for between the planets? A box has a mass of m = 15 kg. What is the force of gravity acting on this box?

Today’s Vocabulary WEIGHT mass

mass

WEIGHT

Spring Scales

Spring Scales

Rules for Using Spring Scales Always check the calibration When there is nothing on the hook, the scales needs to read 0 N. Make sure you hold the scale steady when reading it Bouncing it up and down will give you the wrong weight Read the scale at eye level Your eyes should be at the same height as the pointer

By the end of the period You will have weighed 5 different bags Recorded your data Filled in all of the lab procedures Found the number of pennies in each bag
