The Effect of Mass On a Spring
Aim:
I am doing this experiment to find out what effect mass has on a
spring. In order to find out how the spring extends we will need to
add various amounts of weights to the spring.
Apparatus:
Ÿ Stand
Ÿ Clamp
Ÿ Spring
Ÿ Weights (Newton's)
Ÿ Metre Ruler
Ÿ Goggles
Diagram:
Method:
Once I have all my apparatus set up like above, I will measure the
spring on its own to find its original length. Once I have written
down the measurement in mm's, I will add 1 Newton onto the bottom of
the spring. I will measure to see how long the spring has extended in
mm's. I am measuring the extension of the spring's length in mm's
because the results will be a lot more accurate. I will keep doing
this and measuring the spring to see how long it has extended from the
previous length and the original spring length. I will be doing this
test 4 times going up to 8 Newton's each time. I want to do the test 4
times because I would like to see if there is any pattern in the
extension of the spring.
Prediction:
I predict that the spring will extend each time we add a various
amounts of weights on to the bottom because it will be getting heavier
and heavier causing it to stretch.
Fair Test:
I will be keeping this experiment a fair test by using the same spring
each time I do an experiment and going up to 8 Newton's each time I do
the experiment.
Safety:
To keep this experiment a fair one, I will be wearing goggles because
the spring may flick up and it could catch you in the eye. I will also
be standing up whilst doing the test as the stand we are using may
fall on you. To prevent the stand from falling you could clamp the
3.) Divide your 30g of white substance into the 4 test tubes evenly. You should put 7.5g into each test tube along with the water.
The second test was to put 5 drops of the distillate into a test tube
The materials you will need to properly formulate this experiment are as follows: 1 container of C4 Extreme Pre-Workout w/ NO3, (although you will only need 12 scoops which is equal to 6 servings labeled on the pre-workout container) 3 shaker cups that have oz labels, (labeled oz must have at least 12oz marked on cup) 3 test subjects that are willing to perform the exercises indicated, 2 other persons that will be able to help you record the test runs, a chin up bar that is accessible, and some form of stopwatch that will track the time that is counted in this experiment.
Then, the weight hanger is removed, the platform is spun until the indicator bracket and disk realign, and the apparatus is timed for ten revolutions. To proceed, the radius is changed and the experiment is run identically until measurements are made for five different radii. For the second experiment with variable mass and fixed radius, the apparatus is set up similarly to the first experiment, but the side post stays at the same radius while the weights on the weight hanger are changed. Again, the indicator bracket and disk are lined up for each trial, the weight hanger is removed, and the apparatus is spun for ten, timed revolutions. Likewise, five different weights are measured. In order to calculate the unknown mass of the hanging
Table 1 represents the mass of the block that was used throughout this experiment, which was found to be 0.467kg. In Table 2, the normal force and peak static frictional force were found for the wooden block alone (Table 1) and when it had 500g or 1000g of additional weight. To calculate the normal force, the weight of the block (including the weights added if applicable) was multiplied by gravity. As shown in Table 2, when no additional weight were added to the block, the normal force was 4.58N and the peak static friction was 1.775N. When 500g of weight was added to the block the normal force was 9.48N and the average peak static friction was 3.688N. Then, when 1000g was added to the block the normal force was 14.38N and the average peak static friction was 5.391N. Figure 2 demonstrates the results of the average peak static friction values vs. the normal force,
Newtons second law can be indentified more easily using the equation F=ma. This is an equation that is very familiar to those of us that wish to do well in any physics class! This equation tells us many things. First it tells us the net force that is being exerted on an object, but it also tells us the acceleration of that object as well as its mass. The force on an object is measured in Newtons (I wonder where they got that from). One Newton is equal to one (kg)(m)/s^2. For example, if superman pushes on a 10,000kg truck and it is moving at a rate of 2m/s^2, then the force that superman is exerting on the truck is 20,000N. For those of us that wish to move on in the field of physics, Newtons second law (F=ma) will forever haunt us!

To make this test a fair one, when the light gate is used, we will
Newton’s 2nd Law of Motion states that acceleration is directly proportional to net force when mass is constant. This experiment dealing with variable forces has as its objective the verification of this law. In this experiment this law is tested for verification in straight forward way. Through the use of a Force Sensor and an Accelerometer, data collection of observations and measurements that a force exerts on a small cart along with the cart’s accelerations are to be determined. The sensors’ measurements will be employed to give meaningful relationships between the net force on the cart, its mass, and its acceleration under these conditions. The resultant measurements revealed will verify and determine the force and acceleration relationship as stated by Newton.

In the experiment these materials were used in the following ways. A piece of Veneer wood was used as the surface to pull the object over. Placed on top of this was a rectangular wood block weighing 0.148-kg (1.45 N/ 9.80 m/s/s). A string was attached to the wood block and then a loop was made at the end of the string so a Newton scale could be attached to determine the force. The block was placed on the Veneer and drug for about 0.6 m at a constant speed to determine the force needed to pull the block at a constant speed. The force was read off of the Newton scale, this was difficult because the scale was in motion pulling the object. To increase the mass weights were placed on the top of the ...
This summer when you go to weigh that fat juicy watermelon, think about the mechanics of how the scale works. The basket is attached to a spring that stretches in response to the weight of the melon or other objects placed in it. The weight of the melon creates a downward force. This causes the spring to stretch and increase its upward force, which equalizes the difference between the two forces. As the spring is stretched, a dial calibrated to the spring registers a weight. When designing scales one needs to take into account that every spring has a different spring constant (k). Bloomfield (1997) defines k as “a measure of the spring’s stiffness. The larger the spring constant-that is, the stiffer the spring-the larger the restoring forces the spring exerts” (p. 82).
