                        EXPERIMENT NO.13

OBJECTIVE:

           To construct a-t and v-t graphs from s-t graphs.

APPARATUS:

           Ball, Stop watch, Proctor, Adjustable Screw.

Figure 13.1: Inclined Plane Apparatus

THEORY:

An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load. Moving an object up an inclined plane requires less force than lifting it straight up, at a cost of an increase in the distance moved.

PROCEDURE:

Step#1: Set the inclined plane at an angle of 10⁰ with the help of adjusting screws.

Step#2: Place the steel ball at zero marked distance on the high point /position of the inclined plane.

Step#3: Allow the steel ball to roll on the plane, record the timings of the ball at 25, 50, 75 and 100 respectively.

Step#4: Draw s-t graph (change of position of ball with respect to time).

Step#5: From s-t graph establish v-t graph by measuring the slope  of the graph curve at intermediate points, or establish a mathematical relationship (equation) between S and t.

Step#6: From v-t graph the acceleration can be determined by measuring the slope   at intermediate points. Establish a-t graph.

Step#7: Repeat Step 1 to 4 for new values of angle 15⁰ and 20⁰ respectively.

 

OBSERVATIONS:

CALCULATIONS:

•    Calculate the velocity and acceleration on the basis of experimental values of time and distances.

•    Plot s-t, v-t and a-t graphs using Microsoft Excel.

PRECAUTIONS:

 

1.      The ball must be free from dust and grease and any other matter that may cause resistance in rolling.

2.      Stop watch must be high precision sec. Least Count (L.C.) is preferable.

CONCLUSION:

 Discuss:

•      The shape of curves in the s-t, v-t and a-t graph.

•      The effect of different angles on the result.
