Resistive Force - GCSE Physics Definition

Resistive force is a force that acts against the motion of an object, slowing it down or stopping it. It is often caused by friction, which occurs when two surfaces rub against each other, or by air resistance, which happens when an object moves through the air. These forces make it harder for the object to keep moving in the same direction and at the same speed. For example, when you ride a bicycle, friction between the tyres and the road, and air resistance pushing against you, are both resistive forces. Understanding resistive forces is important in physics because they affect how objects move and how much energy is needed to keep them moving.
