This is a classic introductory physics problem. Basically, you have a cart on a frictionless track (call this m 1) with a string that runs over a pulley to another mass hanging below (call this m 2).

Two masses, a spring, and gravity: A physics problem you need to solve! ⚖️🪢 In this video, we break down a classic physics scenario involving two masses attached to a spring, with gravity acting on ...

Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force found in a spring. And last are resistive forces: ...
