Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could not brake. People would not be able to walk or stand, as the friction between the soles of sh...
The teacher said, “Certainly! When you put oil or smoothen the surface of the road, you slip. This is because the friction is less.” Nitin and Eeshan were walking back home. Nitin took two bananas out of his school bag and gave one to Eeshan. Eeshan said, “This banana peel is so...
1.The rubbing of one object or surface against another. 2.Conflict, as between persons having dissimilar ideas or interests; clash. 3.PhysicsA force that resists the relative motion or tendency to such motion of two bodies or substances in contact. ...
Respect the Laws of Physics, please, by utilizing these fun and informative demos. Could the Magnetic Accelerator be the basis of a perpetual motion machine? Great for open-ended discovery. Constructed from a single strand of thin, flexible metal, the Flow Ring is both a kinetic sculpture and...
In Figure 5, vx1 is the incident velocity component tangent to the strings, Rω1 is the tangential speed of the spinning ball, where R is the radius, and Vc is the contact velocity tangent to the strings where Vc = vx1 + Rω1. Friction acts opposite the direction of Vc and its dura...
The mitotic spindle is a highly dynamic bipolar structure that emerges from the self-organization of microtubules, molecular motors and other proteins. Sustained motor-driven poleward flows of dynamic microtubules play a key role in the bipolar organizat
The Physics Classroom serves students, teachers and classrooms by providing classroom-ready resources that utilize an easy-to-understand language that makes learning interactive and multi-dimensional. Written by teachers for teachers and students, The Ph

Evolving on a planet has warped our sense of physics.在一个星球上进化已经扭曲了我们对物理的感官。If I throw an object away from me, it comes back.如果我把一个物体扔出去，它会回来。That's bizarre! It should just keep going, moving away from me at a constant speed.这非常诡异的好吗！它...
