Sanidhya Jadaun? 7 years, 1 month ago

The closer the molecules are to each other, the less energy it takes for them to pass the sound to each other and the faster sound can travel. It is easier for sound waves to go through solids than through air because the molecules are closer together in solids.Thats why light travels faster in iron than air.....

Thermodynamics is the branch of physics which is concerned with the relationship between other forms of energy and heat. To be specific, it explains how the thermal energy is converted to or from other forms of energy and how matter is affected by this process. Thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.

Action an reaction forces are equal and opposite but they do not balance each other. Why?

Posted by Saksham Dubey 7 years, 1 month ago

CBSE > Class 11 > Physics

1 answers

Yogita Ingle 7 years, 1 month ago

Newton's third Law says: For every action, there's an equal and opposite reaction.

Action and reaction are equal and opposite but do not balance each other this is because the action reaction pair do not act on the same body. Since they don't act on the same body we cannot cancel the forces just because they are equal. Thus eventhough, Newton's 3rd law says each action has an EQUAL and OPPOSITE reaction they don't balance each other.
