Straight line motion is hard to experience on earth because:
1. earth's gravity increases
2. friction and gravity change the motion
3. earth's magnetism get in the way

Why is there friction between objects

Determine the change in width a, height b, thickness t when a plate is subjected to the uniform distributed load and is made of material having modulus of elasticity e=230 gpa and poisson's ratio ν=1/3. given : a=400 mm and b= 300 mm also the uniformly distributed load in downward y direction of plate is 2 mn/m and in the positive x direction is 3 mn/m and t=20 mm

It is really hard for me right know
