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
Possible sources of error in this experiment include the inaccuracy of measurements, as correct measurements are vital for the experiment.
Kinematics unlike Newton’s three laws is the study of the motion of objects. The “Kinematic Equations” all have four variables.These equations can help us understand and predict an object’s motion. The four equations use the following variables; displacement of the object, the time the object was moving, the acceleration of the object, the initial velocity of the object and the final velocity of the object. While Newton’s three laws have co-operated to help create and improve the study of
I am going to carry out an experiment to measure the change in mass of
Newton’s second law explains how the velocity of an object changes when it is subjected to an outside force. In the second law of motion, force is defined to be equal the change in momentum which is mass times velocity per change in time. Since Sir Isaac Newton was also advanced in mathematics, he created a formula to formulate his second law of motion. The formula that he created for his second law of motion is F = m X a. In the formula the F represents force. The M in the formula represents the mass of the object. Lastly, the A represent the acceleration. The entire formula is used to find the product of an object 's mass and its acceleration. Newton’s second law of motion enhanced individuals today to calculate how much force one object
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 ...
The laboratory experiment gives the experimenter a greater chance to control the conditions and enables you to measure behaviour with greater precision. This method also allows for quantative research and also enables greater control of variables. Although it gives the experimenter greater control, this can also seem daunting to the subject who may feel more uncomfortable and is less likely to ...
Before learning the methods from the computer tutorial, I was confused about certain test. B...
The materials used in this lab were an inclined plane, a block of wood, a set of weights, pulley, weight hanger, and a computer. In the first part of the lab, my group and I placed the plane in a horizontal position and the block on the plane and put the attached string over the pulley along with the hooked weights. We adjusted the pulley so that the string would be parallel with the plane. Then, we added weights until the force was sufficient to get the block moving. We repeated this procedure four times adding 100 grams every time. After each time, we plotted the graph on the computer. In the second part of the lab, we used the inclined plane to elevate it to the extent where the block would slide without any external force on it. We repeated this process while recording the angle of the plane and elevating the plane higher and higher. We used this data to determine the coefficient of static friction.
F = ma : where F is force; m is the mass of the body; and a is the acceleration due to that particular force

I’ll be thinking about this next time I feel compelled to check my news feeds. I hope you, sir, will too.
