We used a vernier caliper to obtain the diameter of those two and therefore, the radius. When adding all the numbers together, we found that the true radius(r) of the orbit was 0.139 m. To find our tension, we needed to find out how much weight we needed to pull the object towards away from the spring and on the tip of the pointer as shown below. The tension needed to pull the mass on the tip of the pointer 1.05 kg. In theory the force of acceleration needed to pull the mass to same exact spot should equal the force of tension multiplied by the force due to gravity. Using Newton’s second law, F=ma, we know that the
Upon this discovery, he leapt from his bath and ran naked through the streets shouting, "Eureka! Eureka!" Archimedes had used the concept of density to expose the goldsmith’s fraud. Purpose of the experiment: The objective of this experiment is to calculate the density of series of pennies, to plot experimental data, to interpret a graph constructed from the data and to predict the composition and the pennies and the time they were minted. The Hypotheses: If the mass and volume of a series of pennies is measured, then the density of the pennies can be determined because Density of pennies= Mass of pennies / Volume of pennies Materials and
Gravitational acceleration was found using this formula: g=2ht2 Impact speed of the falling objects was found using this formula: v=2ht Percentage error between calculated values and those obtained from the slope of the graphs were found using this formula: percent error=calculated value-slopecalculated value x100% PROCEDURE Firstly we placed the falling sphere apparatus on the table. Then we placed the meter scale next to the falling sphere
Analysis Isaac Newton is said to be one of the greatest physicists who has ever lived. It was from him that came some of the most significant and important theories, concepts, and laws in Physics, one of which is the Laws of Motion. In this particular experiment, we focused more on Newton’s second law of motion. The second law of motion states that if a net external force acts on a body, the body accelerates. The direction of acceleration is the same as the direction of the net force.
The conflict in this argument arises when individuals appear to have no regard for the environment and keep reproducing even though the earth is becoming severely crowded. The perception of this argument is founded in alarmism and not on the issue as a whole in a globalized world. This paper will refute the theory of overpopulation in favor of proving that the world is indeed under populated and that the idea of overpopulation concentrates, in a biased manner, on lesser developed countries. The intricacies of population cannot be blamed on a sole factor. Instead, the issues of governmental regulations, individual rights, immigration, the cost of children and the burden of a large aging population contribute to the population’s growth or stagnation.
Description: In these series of experiments the apparatus we used was a spring gun that for the first experiment shot a steel ball freely which eventually struck the floor. For the second and third experiments the gun fired the steel ball into a pendulum. To measure the velocity of the steel ball, when it was launched freely, carbon paper and a 2-meter ruler were used to determine the distance it travelled and then kinematics were used to calculate the balls initial velocity. When the steel ball was launched into the pendulum the laws of conservation of energy and momentum were utilized to determine the balls initial velocity. Theory: 3 Kinematic Measurement of Speed In this experiment the steel ball was moving in two dimensions both horizontally and vertically.
The scientific discoveries that he made have given way to new scientific ideas and realizations today. Isaac Newton created the 3 Laws of Motion. These laws explain the properties of motion, why objects move in a certain manner, and what causes them to move that way. The first law of motion, also called the law of inertia, states: “an object in motion stays in motion unless acted upon by an unbalanced force. An object at rest stays at rest unless it is acted upon by an external force.” This means that when an object is moving, it will stay moving unless a force interferes with it.
Tectonic Plates:- The movement of Continental plates, furthermore renowned as Tectonic Plates, is renowned as “Tectonic Movement”. It is a technical theory that recounts the large-scale movement of Earth's lithosphere i.e. the outer layer of earth. Geologically, the outer layer of earth, which is also renowned as “Crust”, is divided into “lithosphere” and “Asthenosphere”. This is founded on dissimilarities in mechanical properties and in the procedure for the transfer of heat.
What is the Big Bang' theory? What evidence does this theory rest upon? In your conclusion, indicate whether you think the Big Bang theory counts as 'history'. Over the history of mankind, people have been trying to explain the birth of the universe. Numerous theories were proposed by scientists or religions to explain the beginning of the universe.
Stephen Hawkings. Our Picture of the Universe Scientist describe the universe in terms of two basic partial theories- the general theory of relativity and the quantum mechanics. The first describes the force of gravity and the large-scale structure of the universe. Quantum mechanics on the other hand, deals with phenomena on extremely small scales. Unfortunately they are not consistent between each other, and that is one of the major endeavors of physics, to find a theory that unifies them both.
