2.1 Find the acceleration of a ball rolling down
an inclined angle iron by drawing a graph
between 2S and t2
Date ________________
In this experiment the motion of a body along an inclined plane is observed.
• The initial velocity 'vi ' of the ball at the time of release is zero.
• The acceleration 'a' during this motion is considered as uniform and is
obtained from equation of motion
S = vit + 1 at 2
2
then a = 2S
Since vi = 0 t2
If a graph is drawn between 2S and t2 then the slope 2S will be equal to
acceleration ‘a’of the ball. t2
