Friction

This topic explains that if a force is applied along the left, friction acts along the right direction. If force is applied along the right, friction acts along the left direction. The force of friction always opposes the applied force. Let us learn it in detail here.

This topic discusses the various factors that affects friction. Friction is caused by the irregularities on the two surfaces in contact. It is explained by various activities to understand the concept.

This topic explains the frictional force. It describes different causes of friction force. We will also learn about the ridges and grooves on a surface that causes friction.

Do you know why we add powder on the carrom board? Because it reduces the friction. In this topic, we are going to discuss the methods to increase and decrease friction in detail.

This topic describes fluid friction. We know that air is light but yet, air exerts frictional force on objects moving through it. Similarly, water and other liquids exert force of friction when object moves through them.
