Furthermore, the qualitative relationship between mass and acceleration can be seen by a comparison of the numerical values in the above table.

The Direction of the Net Force and Acceleration As stated abovethe direction of the net force is in the same direction as the acceleration.

The difference between these, divided by the time between them, yields the acceleration. Pull the trolley back so that the mass is raised to just below the pulley. The slope of the graph without any added weights was 0. And similarly, rows 4 and 5 show that a halving of the mass results in a doubling of the acceleration if force is held constant.

If so, what is the value of the slope? Similarly, comparing the values in rows 2 and 4 demonstrates that a halving of the net force results in a halving of the acceleration if mass is held constant.

Analysis Depending upon the software, the results may be displayed on a bar chart as the experiment proceeds. Whatever alteration is made of the net force, the same change will occur with the acceleration. Double, triple or quadruple the net force, and the acceleration will do the same.

Use a ruler to help you to stretch the cord by a fixed amount, or extend the cords the full length of the trolley. Even though it is treated as frictionless, friction is always present everywhere, even if it is regarded as not present.

Click on the Set Current to Standard Value to set the 4. Do not use trolleys with bent axles through dropping. Then click the buttons to view the answers. Record the slope of the line, m, in Table 1 as the acceleration, a, of the cart.

Cart with No Blocks Describe your data collection techniques for recording the acceleration of the empty cart. See Answer The net force is to the left since the acceleration is to the left.

See Answer The net force is to the right since the acceleration is to the right. The law states that unbalanced forces cause objects to accelerate with an acceleration that is directly proportional to the net force and inversely proportional to the mass.

Thus, the stated hypothesis was confirmed that if the force was increased, the acceleration would also increase. Cart with Blocks Weigh a second, empty cart. You can find it in the Physics Interactives section of our website. This value could then be compared to the mass calculated from the force of the free hanging system.

Acceleration is directly proportional to net force.relationship between force, mass, and acceleration. Theory According to Newton’s Second Law, the acceleration, Experiment 5: Newton’s Second Law 31 PROCEDURE PART 1: Vary the Mass of the Cart, m a Determine acceleration for this heavier cart.

Trial #3 Remove m. According to NASA, this law states, "Force is equal to the change in momentum per change in time.

For a constant mass, force equals mass times acceleration." For a constant mass, force equals mass. 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. To observe the relationship between force and acceleration.

To test the hypothesis that force is equal to the mass times the acceleration (Newton’s Second Law) To define “inertial mass” as a slope.

Equipment: Determine the total mass of the two carts, the force sensor, and the blocks. The relationship we can see through this experiment showed that as the mass of the object became greater, while the net force stayed the same, the acceleration became less.

When the mass and acceleration are graphed (on the graph titles Mass and Acceleration) it doesn’t form a straight line, thus not proving Newton’s Second Law. The Second Law goes on to mathematically define the exact relationship between force and acceleration: The acceleration of an object is directly proportional to the sum of all the forces acting on it and is inversely propor.
