Friction Problem

Two masses M1 and M2 are connected by a light rod and the system is slipping down a rough incline of angle theta with the horizontal. The frictional coefficiant at both the contacts is u fhnd the accelaration of the system and the force by the rod on one of the blocks. Friction problem from … Continue reading Friction Problem

Numerical Problem from Friction

“The friction coefficient between a road and the tyre of a vehicle is 4/3.find the maximum incline the road may have so that once hard brakes are applied and the wheel starts skidding,the vehicle going down at a speed of 10m/s is stopped within 5m”...

Solving problems from kinematics and friction

I just want to know how to easily solve problems related to kinematics and friction.

Misconception on Work and energy conservation

It is said that when work is done energy is lost. But when a man runs in a circular path and reaches the starting point, then the work done is zero but energy is lost. (Divyam asked) Answer: The work done here is not zero, work is done and energy is spent to overcome friction. [...]

The Physics of Figure Skating

To see physics in action in everyday life, look no further than figure skating. And as the men hit the ice to show off their spins and combinations Tuesday in the Winter Olympics, here's a perfect chance to watch examples of basic scientific concepts, such as friction, momentum, and the law of equal and opposite … Continue reading The Physics of Figure Skating
