IntroductionNewton’s Second Law

Newton’s Second Law of Motion

The acceleration of a body is directly pro-portional to, and in the same directionas, the net force acting on the body, andinversely proportional to its mass.

F = ma ................ (1)

Where,F = Forcem = mass of the objecta = acceleration of the object

Objectives of this Experiment

Objective

The main objectives of this are

1 To capture the motion of an object that is moving at thesame speed without changing direction.

2 To analyze the video using Tracker to extract the objectsposition and corresponding time, the experimental model.

3 To construct a computational model using VPythonprogramming that accurately describes the observations basedon physics principles (Newton’s second law).

4 To compare the experimental model with computationalmodel using spreadsheet.
