Observe some of the phenomena around your home. look for something that you can’t explain right away, but that you could test with an experiment. then, design an experiment that you could conduct at home. make sure to identify the independent, dependent, and controlled variables. you should also write your own hypothesis. you don’t need to perform the experiment, just identify the variables and write hypothesis

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.
