Unit 4 Lesson 1 Kinetic and Potential Energy: PE Focus

A group of scientists wanted to know if the size of filter paper would impact the amount of time it takes the filter paper to rise during a chemical reaction. Several different sized filter-paper disks were soaked in a beaker with a solution and placed into another beaker with a solution where a chemical reaction took place that produced a gas. The gas bubbles collected on the filter paper, making the filter paper rise to the top of the solution.  What is the dependent variable for the experiment?

Which skier has more potential energy?

Blue or yellow?

0:43 - Which ball do you think will bounce the highest when dropped?

The diagram shows two of equal mass. Ball A is resting near the edge of a shelf. Ball B is resting on the ground below. Which of these statements best describes the diagram above?

What happens to the kinetic energy and gravitational potential energy of a ball during free fall?

Tom pushed the ends of a large spring together. He had to hold on tight so the spring did not expand in his hands. What type of energy of the spring was increased?
