what will happen to the instantaneous velocity, instantaneous speed, average velocity and average speed when particle moves with non uniform velocity in staright line??
Answers
Explanation:
When a particle is moving with constant velocity then its magnitude and direction both are not changing means particle must travel in straight line. Also when particle is moving in straight line with no acceleration then distance covered and displacement both will be same in same interval of time.
Answer:
☆Potential:
it is the ability or something we can say stored in the object when it is at a height.
- it is because whenever we go any higher to the earth's surface , the strength of the earth,the gravity creates the pull, and it always acts on the object.
☆ but when it suddenly gets released from that height, the gravity will acts as it was acting previously.
it's the sole reason for coming down of object. So more the more object gets nearer to earth gravity gets higher.
(but we take the g constant, bcz in our ques the height is negligible compared to earth's radius)
- so it's accelerating with a constant rate of g, and as acceleration is acting , it will give some velocity to the object
- so its that what object possess after falling from a height,the velocity which it possess is a form of some energy right? and that's how the whole mgh is changed to KE.
hope it gets fit in your cerebrum! and clears the doubt !!
Good luck.
