Physics Newtons 2nd Law Lab
Newton`s Second Law – Lab Report
Name: Tasneen Ahsan Date: 19th November, 2012
Purpose
To show how the acceleration of an object changes when, the mass changes and the net force is kept constant and when the mass is the same..
Hypothesis
I predict that by changing the mass of the object will result in a change in the acceleration as Newton`s second law states that the magnitude of the acceleration of any object is directly proportional to the magnitude of the net force, and inversely proportional to the mass of the object. So if the total mass of an object is constant, the more net force acting on an object, the faster it will accelerate,. If the net force is constant and the mass is different, then the acceleration is inversely proportional to the mass of the object, which means the more mass the object gains, the slower it will accelerate.
Materials
* * Dynamics cart * Pulley * Clamp * Motion detector * Tapse * String * Set of masses * Cardboard piece * Computer interface
Procedure
Acceleration and Net Force 1. The equipment was set up like the diagram shown on page 150 figure 1 and the mass of the cart was measured 2. Placed 900g of weight on the cart and 100g of weight hanged from the string 3. The cart was held stationary and placed at its starting point 15cm away from the sensor. The cart was released in a way the motion detector can easily work to gather the data. Data were recorded by analyzing the graphs and finding the slope of the velocity-time graph. Print screened the graph for later use 4. Conducted the same process for second trial 5. Reduced masses from the cart and repeated the procedure again 6. Kept adjusting the masses on the cart and the suspended masses and repeated the process until enough data was collected
Acceleration and Mass 1. Used the same cart setup from Part A, with no mass on the cart and suspended mass of 200g
