3A20.15 - Compression Springs - Different K Same M

Title3A20.15 - Compression Springs - Different K Same M

​To demonstrate how compression springs follow Hookes' Law using the same mass and three different k-valued springs

Assembly Instructions

Need a camera and backplane.  Place a tape mark on the table so the professor can place the tube in the correct place each time they remove the spring from the tube assembly.  ​

Operation Instructions

Place one spring in the tube assembly.  Note the starting position.  Drop the mass in the tube assembly and observe the spring compression.  Remove that spring and put another one in the tube assembly.  Drop the mass in the tube assembly and observe the different amount of compression of that spring compared to the previous spring.  Optional: do it a third time with another spring for comparision purposes.​

​F = -kx
Larger the K, stronger the spring force, less compression occurs
