The person sitting inside the crate has a mass of 61 kg. The washer is at rest with respect to the crate when the string makes an angle of 56 degrees with the top of the crate. However, it is impossible for the crate to slide down the ramp with a coefficient of kinetic friction of...
What is kinetic friction? What are the units of linear momentum? A 0.300 kg ball has a speed of 15.0 m/sec. What is its kinetic energy? If the speed were doubled, what would be its kinetic energy? What is its rotational kinetic energy?
What is law of equipartion energy? Show that energy per molecule per degrees of freedom is frac(1)(2) KT. View Solution A polyatomic gas with n degrees of freedom has energy per molecule given by : View Solution Exams IIT JEE
types: static friction force and kinetic friction force. In the first case, it is the friction force felt by an object that does not slide over another but is in a state of imminent motion. In the case of the second, it is the friction felt by a body moving on the surface of ...
Friction is the name given to the force that resists the initiation of sliding motion between two surfaces; it is all around us and it occurs at all length scales. Whereas friction between two macroscale surfaces is proportional to normal force, at the n
Static friction operates between two surfaces that aren't moving relative to each other, while kinetic friction acts between objects in motion. In liquids, friction is the resistance between moving layers of a fluid, which is also known as viscosity. In general, more viscous fluids are thicker,...
Hi, A child on a swing swings with a time period of 2.5s and an amplitude of 2m. What is the max. kinetic energy of the oscillation? I'm not sure how to...
There are essentially two kind of coefficients; static and kinetic. The static coefficient of friction is the coefficient of friction that applies to objects that are motionless. The kinetic or sliding coefficient of friction is the coefficient of friction that applies to objects that are in motion...
Identify the formula for rotational kinetic energy, which is given by $K = \frac{1}{2} I \omega^2$, where $I$ is the moment of inertia and $\omega$ is the angular velocity. Calculate the moment of inertia $I$ for the Earth, assuming it is a uniform sp...
Static friction (the force that must be overcome at the onset of kinetic motion) is proportional to the number of such links formed during the time of stick.doi:10.1007/BF00157970Günter ReiterA. Levent DemirelJohn PeanaskyLenore CaiSteve Granick...
