1. Form hypothesis: Suppose you already know how many ants it takes to lift an object straight up (using the 10-cm stick). How can you predict the number of ants that will be needed to lift
the object with an inclined plane of a certain length?
Hint: Play with the Gizmo. See how doubling the length changes the number needed.

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
