How do static friction oppose motion ? Value of coefficient of friction depend on which factors ?
Meena applies the front brakes, while riding on her bicycle along a flat road. The force that slows her bicycle is provided by the
For the given figure, if block remains in equilibrium position then find frictional force between block and wall ........ $N$
When two surfaces are coated with a lubricant, then they
An army vehicle of mass $1000\, kg$ is moving with a velocity of $10 \,m/s$ and is acted upon by a forward force of $1000\, N$ due to the engine and a retarding force of $500 \,N$ due to friction. ........... $m/s$ will be its velocity after $10\, s$
Pulling force making an angle $\theta $ to the horizontal is applied on a block of weight $W$ placed on a horizontal table. If the angle of friction is $\alpha $, then the magnitude of force required to move the body is equal to
