🌈 Rainbow Mindmap of Friction
Definition of Friction
Friction is a force that resists the relative motion between two surfaces in contact.
Types of Friction
Static, Sliding, Rolling, and Fluid friction – each type occurs under different conditions.
Causes of Friction
Friction is caused by the roughness of surfaces and the interlocking of microscopic bumps.
Advantages of Friction
Friction helps in walking, driving, writing, and holding objects.
Disadvantages of Friction
Friction causes wear and tear, reduces efficiency, and generates unwanted heat.
Reducing Friction
Lubricants, smooth surfaces, and ball bearings help reduce friction in machines.
Real-Life Applications
Used in car brakes, climbing gear, athletic shoes, and industrial machinery.
