What is the meaning of topple in Physics? Explain how rubbing two objects together causes them to have equal and opposite charges. Is it true that cats cannot see objects unless they are moving? Can a body be in equilibrium, if it is in motion? Explain. ...
What does alpha mean in physics? What is meant by drift velocity? Define drift velocity. What is the meaning of divergence in physics? Give an example. What is meant by the term Moment of Inertia? What is the equation: x = x_0+v_{0t}+\frac{1}{2}at^2 used for (physics)?
Less friction means it is harder to stop. It is because of this reason that you hear of many accidents during monsoons. Even though the friction of the brakes is still there, the brakes may be wet, and the wheels are not in as much contact with the ground because of the water. Althou...
but because of friction from the surface, the wheel spins in a clockwise direction, meaning that the direction of friction is backwards (to the left). Answer should be C. If a torque is applied to the wheel, then the wheel is already spinning. Contact with the surface pushes the wheel ...
In physics, the torque is a perpendicular force that acts over a pivot point with the help of an arm. Rotational force is another name for the toque that clearly elaborates its meaning and function. Moreover, the rotational force or torque in cars play a significant role in internal combust...
What is viscosity? Learn the meaning and formula of viscosity with equations and examples. Understand the methods of measuring the viscosity of a...
In summary, my professor said that the moment of inertia of a system is equal to the sum of the moment of inertia of each of its masses. However, I don't see why we can use R here rather than the distance from the center of the pulley to the mass. Isn't the moment of inertia...
What does an Engineer need to Think About when Designing Products or Friction/Wear Experiments? What is GGB's Approach to Developing Bearing Solutions through Tribological Expertise? What are some of GGB's Achievements in the Field of Tribology as they Apply to Bearing Solutions?
Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
Neither is the levitation effect achieved in 2007 by countering Casimir force, a quantum force that essentially causes objects to stick to one another -- a type of nanofriction [source: ScienceDaily]. Antigravity, on the other hand, involves lessening the effects of gravitational pull on an ...
