In the world of physics, force plays a crucial role in determining an object’s motion, equilibrium, and other aspects of its behavior. One such concept is the resultant force, which refers to a single ...

Tension is the force applied on a rope, cable, or wire that causes it to stretch when subjected to external forces. In simple terms, it is the measure of force needed to keep an object in static ...

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).

Listen to the full series on BBC Sounds. Newton's first law can also be used to explain the movement of objects travelling with non-uniform motion. This includes situations when the speed changes, the ...
