A uniform circ.ular moti.on is an accele.rated m.otion expl.ain it. State whet.her the accelerati.on is unifor.m or vari.able? Name the fo.rce resp.onsible to caus.e this acceler.ation. What is the direc.tion of the for.ce at any inst.ant. Draw a diagram to support the answer. |
|
Answer» Answer: • A uniform circular motion is an ACCELERATED motion because direction of the object changes at each point in the circular path and so the object get accelerated • As the direction and magnitude of the object is changing , the ACCELERATIONS said to be variable • The force responsible to cause this ACCELERATION is CENTRIPETAL force towards the centre • The direction of the force changes at each point Refer to the above DIAGRAM ! |

What is time? how it acts on motionless ? |
|
Answer» Answer: Time in physics is defined by its measurement: time is what a clock reads. In CLASSICAL, non-relativistic physics, it is a scalar quantity (often DENOTED by the symbol and, like length, mass, and CHARGE, is usually described as a fundamental quantity. Time can be COMBINED mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and SCIENTIFIC issues, and part of the foundation of recordkeeping. |

Friction between rigid rod of mass m and wedge of mass 2m is zero while coefficient of friction between groundand wedge is 0.1.A force Fis applied on the wedge so that rod moves with constant velocity vo = 5 m/s in upwarddirection as shown. The power delivered by force F will beW. (take m = 1 kg, g = 10 m/s2) |
|
Answer» Answer: In the situation shown in figure, a wedge of mass m is PLACED on a rough surface, on which a block of equal mass is placed on the inclined plane of wedge. The friction coefficient between the wedge and the block and also between the ground and the wedge is μ. An external force F is applied horizontally on the wedge towards the right, assuming block does not SLIDE on the wedge. Find the minimum value of Force F at which the block will START slipping. Explanation: N 1
=mg+mg=2 m g N 2 mgcosθ+m awithoutθ Here, f 1 and f 2 are the frictional force and force m awithoutθ ispseudo force and acceleration of the system is a F−f 1 =(m+m)a a= 2 m F−2μmg
If block start slipping then m acosθ=mgwithoutθ+f 2M acosθ=mgwithoutθ+μ ( m gcosθ+m awithouti ) a ( cosθ−μwithouti )=g(sinθ+μcosi )a= (cosθ−μwithouti ) g(sinθ+μcosi ) 2 m F−2μmg= (cosθ−μwithouti ) g(sinθ+μcosi ) F=2m[μg+ (cosθ−μwithouti ) g(sinθ+μcosi ) |
