TITLE: NUMERICAL VERIFICATION OF NEWTON’S SECOND LAW OF MOTION

OBJECTIVES:
1. To numerically examine the relationship between force, mass and acceleration. 2. To find the acceleration of the cart in the simulator. 3. To find the distance covered by the cart in the simulator in the given time interval.

EQUIPMENT:
1. Newton’s Second Law of Motion Virtual Lab simulator. 2. Computer

INTRODUCTION:
Newton's laws are applied to objects which are idealized as single point masses in the sense that the size and shape of the object's body are neglected in order to focus on its motion more easily. This can be done when the object is small compared to the distances involved in its analysis, or the deformation and rotation of the body are of no importance. In this way, even a planet can be idealized as a particle for analysis of its orbital motion around a star. Newton’s second law of motion can be used conveniently to derive the equation of motion of a system under the following conditions: 1. The system undergoes either pure translation or pure rotation. 2. The motion takes place in a single plane.

3. The force acting on the system either have a constant orientation or are oriented parallel to the direction along which the point of application moves.

THEORICAL PRINCIPLE:
Newton’s second law of motion states that the rate of change of momentum of a body directly proportional to the force acting on it and takes place in the direction of the applied force.

The mathematical expression of Newton’s second law of motion is F (mv-mu)/t
F m(v-u)/t
F ma
Where m is the mass of a body, v is the final velocity of the body, u is the initial velocity of the body and t is the...
