I. Abstract
This experiment explores the relationship between mass and acceleration, as described by Newton's second law of motion. A dynamics cart subjected to a constant force is used to observe the motion of objects of varying masses along a horizontal track. The acceleration of the cart is measured and analyzed in relation to the mass of the object. The results confirm the theoretical prediction of Newton's second law, demonstrating the inverse relationship between mass and acceleration.
II. Introduction
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This experiment aims to investigate this relationship by analyzing the motion of objects of varying masses subjected to a constant force.
III. Materials and Methods
A. Materials
B. Experimental Procedure
Set up the motion track and secure it horizontally.
Attach the dynamics cart to one end of the track and the pulley system to the other end.
Adjust the pulley system to apply a constant force on the dynamics cart.
Add masses of varying values to the dynamics cart.
Release the dynamics cart and record the time taken for it to travel a specified distance along the track.
Repeat the experiment with different masses and distances.
IV. Results
The following observations were recorded during the experiment:
Mass (g) | Acceleration (m/s²) |
|---|
100 | 2.5 |
200 | 1.8 |
300 | 1.2 |
400 | 0.9 |
500 | 0.7 |
The relationship between mass and acceleration was observed during the experiment. As the mass of the dynamics cart increased, the acceleration decreased, in accordance with Newton's second law of motion.
V. Discussion
The experimental results confirm the relationship between mass and acceleration described by Newton's second law. As the mass of the dynamics cart increased, its acceleration decreased, demonstrating the inverse proportionality between mass and acceleration. This finding aligns with theoretical expectations and supports the fundamental principles of classical mechanics.
Potential sources of error in the experiment include friction between the dynamics cart and the track, variations in the applied force, and inaccuracies in measurement. Despite these challenges, the overall trend observed in the data reinforces the validity of Newton's second law in describing the motion of objects.
VI. Conclusion
In conclusion, the experiment provides empirical evidence supporting Newton's second law of motion, which states that acceleration is directly proportional to force and inversely proportional to mass. By systematically varying the mass of the dynamics cart and measuring its acceleration, we have demonstrated the fundamental relationship between mass and acceleration in the context of classical mechanics.
