500
How could you use each of these simple machines to help you complete work? Draw a picture of how you would use each of these. a) pulley b) wheel and axle c) ramp
a) pulley - can be used to pull an item up by pulling on one side of the string (example: lifting a water bottle up or lifting a flag up a flagpole) b) wheel and axle - can be used to help move objects with less force (example: adding wheels to a book basket to move books with less force) c) ramp - can be used to help objects move with less force in the same direction as gravity (example: a slide helps you move down quickly)
500
When you are bouncing a ball what force is used most often. a. pushing b. pulling
a. pushing. You are pushing the ball down to the ground or away from your body.
