Stress is a force acting on a rock per unit area. It has the same units as pressure, but also has a direction (i.e., it is a vector, just like a force). Strain is a change in shape or size resulting from applied forces (deformation). Rocks only strain when placed under stress.

ANSWER

I have a query in Conservation of momentum. Pls. help. We know that in both elastic & inelastic colission momentum is conserved. In inelastic collision, let sound is produced which means that particles in surrounding air are hit, thus they will move, so they will also have some momentum. My question is are these particles also included in the system?

Laws of limiting friction

Posted by Tarun Singh 8 years, 5 months ago

CBSE > Class 11 > Physics

1 answers

Abhi Bhai 8 years, 5 months ago

Laws of kinetic or limiting friction 1. The direction of limiting frictional force is always opposite the direction of motion. 2. Limiting friction acts tangential to the two surfaces in contact. 3.The magnitude of limiting friction is directly proportional to the normal reaction between the two surfaces. 4. The limiting friction depends upon the material, the nature of the surfaces in contact and their smoothness. 5. For any two given surfaces, the magnitude of limiting friction is independent of the shape or the area of the surfaces in contact so long as the normal reaction remains the same.
