Velocity of a body in circular or curved path is variable why give reasononly​

Physics
1 answer:
Svetradugi [14.3K]3 years ago
3 0

Because "velocity" means the speed and direction of the motion.

In circular motion, or motion on any curved path, the direction is constantly changing.  So even if the speed isn't changing, the <em>velocity</em> is.

What is the difference between a negative feedback system and a positive feedback system?
Anni [7]

Answer:

D

Explanation:

The negative feedback is responsible for maintaining equilibrium (stability) in a system as it lessens effects, which is contrary to positive feedback which increases reaction and moves a system further away from equilibrium (stability), It does so by amplifying the effects of a product or event and occurs when something needs to happen quickly. e.g

  • Insulin lowers down blood sugar levels, so when the body detects that it has too much sugar, the pancreas is prompted to release insulin and only stops when balance is achieved; hence, negative feedback.  
  •  When there is a tear on the skin, a chemical is released. This chemical causes platelets in the blood to activate, hence they release a chemical which signals more platelets to activate, until the wound is clotted, positive feedback.
