# An experiment on newtons 2nd law force vs acceleration to determine the relationship between the for

We learned that our prediction at the start of this experiment was proven to be correct. Even though it is treated as frictionless, friction is always present everywhere, even if it is regarded as not present. Run the string over the smart pulley see figure 2.

Observe your two tables: Be sure the end stop is on the smart pulley end of the track to keep the cart from ramming the set up. Set the Sample Rate to Hz. Position the cart at the far end of the track. Record the combined mass of the cart and force sensor: Fix a 1 kg mass on the trolley with Blu-tack to make the total mass trolley plus mass of about 2 kg.

This will fit a straight line to your data. Complete the report in WORD. Sometimes it isn't enough to just read about it. Click on the Record button as your lab partner releases the cart; make sure to stop the cart before it crashes to the floor. You may wish to modify borders in the tables.

Include sketches, plots, and descriptions of expected results. Thus, if the direction of the acceleration is known, then the direction of the net force is also known. The track should be totally horizontal. We hypothesized that as the mass on the hanger increases, the air resistance, will decrease, thus the acceleration of the object towards the center of the earth would be increased.

The hanging mass should be just below the smart pulley. This will prevent toes or fingers from being in the danger zone. What is the tension in the connecting string in terms of m, M and g. Double, triple or quadruple the net force, and the acceleration will do the same.

In regards to the trial with the added weight, the calculated value of 0. Describe what measurements you made, and what methods you used to collect data. The aim of this datalogging experiment is explore the relationship between the magnitudes of the external force and the resulting acceleration.

Investigating Newton's second law of motion Demonstration A trolley experiences an acceleration when an external force is applied to it. In some experiments (such as Investigating Newton's second law of motion) the force accelerating the mass is provided by hanging masses; their weight provides the force. However, this assumes that weight is proportional to mass, and so the relationship that the experiment is designed to show is already assumed in the design of the experiment.

Testing Newton’s 2nd Law Goal: To test Newton’s 2nd law (ΣF = ma) and investigate the relationship between force, mass, and acceleration for objects. Lab Preparation To prepare for this lab you will want to review what a velocity vs. time graph law is supported by the experiment.

Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object.

The law states that external forces cause objects to accelerate, and the amount of acceleration is directly proportional to the net force and inversely proportional to the mass of the object. PWV #9: Collect force and acceleration data for a cart as it is moved back and forth.

Compare force vs. time and acceleration vs. time graphs. Analyze a graph of force vs. acceleration. Determine the relationship between force, mass, and acceleration.
