Two books are sitting on top of two different desks. Book A is sitting on a desk that is 4 feet high. Book B is sitting on a desk that is 6 feet high. Which book will make the louder bang if pushed off the desk? Explain in terms of energy.
what is book B because is has a greater amount of potential energy.
Nell uses a rubber band wrapped around the legs of a chair to launch a ball. She discovers that the farther she pulls back with the rubber band, the faster the ball will travel. Nell draws the following conclusion: Increasing the weight of an object will increase its speed. Is her conclusion correct in this experiment? Explain in terms of energy.
A student pushed a dime into another dime. They did this experiment two times. In trial 1 they pushed the dime gently. In trial 2, they used a stronger push. In terms of sound what prediction could you make about the results of this experiment?
what is trial 2 would produce a louder sound than the sound produced by the collision in trial 1
what type of energy does a bow have when you pull back the arrow?
what is potential energy
