This video discusses how to determine the amount of work done on a system for many scenarios, both graphically and using an algebraic equation. The definition of work is also used to derive an equation for the amount of energy stored in the gravitational potential energy account.

Spring Force vs Stretch Investigation

Below are 9 videos that can be used to determine the relationship between the stretch of a spring and the force exerted by the spring. The videos below are grouped by the type of procedure used to collect the force and stretch data.

Procedure #1: Hanging Masses on a Spring
Each video shows a spring hung vertically and various masses are used to stretch the spring. The gravitational force on each mass can be used to determine the amount of force exerted on the spring that is the same as the force exerted by the spring. A different spring is used in each video for variation in the collected data. The links for all 6 videos are below.

Procedure #2: Stretching a Horizontal Spring Attached to a Force Sensor
Each video shows a spring attached to a force probe/sensor that is stretched to different lengths. The force probe reading is shown in real-time on a computer screen and the meter stick can be used to estimate the spring’s change in length or “stretch”.
