The video tutorial explains how force is influenced by an object's mass and acceleration. It introduces the concept of force as a push or pull, measured in newtons, and provides examples using a toy train and a real train to illustrate the calculations. The tutorial also demonstrates how to rearrange the force formula to find mass and acceleration, using practical examples with cars.
