Today, we discussed different ways to make objects move or change speed. We moved our shoe boxes by pushing, pulling, and sliding it down an inclined plane, because gravity caused it to move. We also discussed why our boxes were harder to push up the slope when added rocks. We decided that we increased the friction in our boxes, which caused the shoe box to push down harder on our table. Friction causes things to slow down or makes things harder to move.
Homework for Tuesday:
Find objects around your house that work, use, or can make these different forces. Write 3-5 examples down in your journal for each force (Pushing, Pulling, Gravity, and Friction).
Here are some different examples of each force we explored today!
Pushing a basketball from your hands to make a basket.
Pulling coke tab open with your fingers
Skiing down a mountain because gravity is pulling you down.
Sliding into 2nd base and slowing down because of friction.
Watch this video about Forces on BRAINPOP. Start at 2:00.
