motion in 1 dimension

motion in one dimenton

1. motion in one dimension - particle moves along a straight line.
2. sign convention -1.towards right= +ve 2.towards left = -ve
3. uniform velocity - body covers equal displacement in equal amounts of time.
4. variable velocity - body covers unequal displacement in equal amounts of time.
5. average velocity = total displacement / total time.
6. accelerated motion - velocity changes with time
7. uniform acceleration- equal change in velocity in equal amounts of time
8. variable  accelration-unequal change in velocity in equal amounts of time
9. av. velocity in accelrated motion =final vel - initial vel./
10. eq. of motion =>
1. 1 v = u+a
2. s=ut+14/2at 
3. v squared + u squared =2as
• p.s.-same method can be used to solve questions related to motion in 2 and 3 dimensions by applying the above equations in x y and z direction
• p.s.s. next post newtons laws of motion
