sir in average speed and average velocity how the time taken is t2-t1 and why we shouldn't sum it as t1+t2..

Post your answer here

Sir, reference can also be related to earth's rotation; we move (rotate rather) alon with the earth in a rotation(day). This can also be related with the motion of a body in a bus or a car. One more point(though this point is not related) hanging in air(if possible) would take us to different countries without any motion and we could clearly see earth's movement! Though this is a query box, i just wrote these things as this box were a discussion box. THANK YOU ASHISH SIR for these videos and this opportunity.

sir is all lessons are completed and is they are sufficient for iit

5 years ago by Abhishek Jadhao

Post your answer here

if Velocity of a body at an instant is zero then its acceleration should also be zero at that instant because instantaneous acceleration is given as vdv/dx where v is the velocity at any instant. so on substituting v=0 in given formula instantaneous acceleration should be zero. but why is it not so? sir pls pls help me

how can we say that motin and rest are relative terms

6 years ago by SRI RISHITHA

Ans 1 ->

It depends on the frame of reference chosen....For example the same old case of sitting in a train...According to the people in the train,I am at rest whereas according to someone outside I am in a state of motion....Hope it helps

Sir the answer to the 12th question in QuSet 4 (on Motion in One Dimension) given is wrong. The answer should be a. whereas answer key given is c.

7 years ago by Abhijith S Raj

Ans 1 ->

c is correct answer because velocity is changing its direction after reaching maximum height

sir plz help a particle moving in a straight line with a constant acceleration.it changes its velocity from 10 ms to 20 ms while passing through a distance 135m in t secong.what is t

9 years ago by Hritwik Pareek

Ans 1 ->

it is 9 sec. find it using 1st and 2nd equation of motion

9 years ago by shashank pandey

Ans 2 ->

its so simple you will get 2 equations solve it answer is 9 seconds

9 years ago by Tanay Gawade

Ans 3 ->

it can be solved just by 1 equation i.e. s=(v+u)t/2

9 years ago by Meghansh Punjabi

Ans 4 ->

Beta your target is to find time. Now what is given in question you have initial velocity(u) as 10m/s and final velocity(v) as 20m/s and distance givengiven(s) is 135m. So let's write all euationseuations S=u×t+1/2at2 V=u+at V2=u2+2as So beta first find a from equation 3 and put it in eq2 to get your answer. Tips: Always read the question carefully Draw diagram Understand what has been asked and make that your target.

8 years ago by Gurpreet Singh

Ans 5 ->

Dear Meghansh Punjabi how did you got that formulae..s=(v+u)t/2..plz ..explain

what is the distance

10 years ago by niteesh kumar

Ans 1 ->

a scalar quantity always positive cannot be zero formula wise= speed * time also equal to displacement in some cases.

10 years ago by Dr.Upendra Singh

Ans 2 ->

it is the length of the path covered by a particle which is independent of initial and final states of the particle where as displacement depends on the initial and final state of the particle.

10 years ago by archana050968@gmail.com

Ans 3 ->

Length of path travelled

10 years ago by manish reddy yedulla

Ans 4 ->

Distance is the path length traversed by the body.

10 years ago by Dhanush K

Ans 5 ->

it is the length of the actual path traversed by a body between its initial and final positions.

10 years ago by mudit

Ans 6 ->

The length of the actual path travelled by a particle during a given interval of time is called as distance. The distance travelled is a scalar quantity which is quite different from displacement. In general, the distance travelled between two points may not be equal to the magnitude of the displacement between the same points.

10 years ago by Akshat Mathur

Ans 7 ->

Distance is the total length of the path traveled. It is a scalar quantity.

9 years ago by Vasu Goel

Ans 8 ->

A SCALAR isn't that simple????

9 years ago by Pranay Rahul Ganji

Ans 9 ->

distance is defined as total path length traversed
