A persons mind is unique. Every person has his or her own way of thinking and learning. Not to mention, people come from different origins, which leads to some people having a higher vocabulary. Why is all this important in physics? In the article, “Talking to Learn Physics and Learning to Talk Physics” it states, “the development of physics discourse and conceptual understanding are different processes that depend upon one another for successful physics learning (Harlow, Otero 1).” This article…
scales contain springs, although these are normally hidden from view. When you stand on a bathroom scale, the scale measures just how much upward force it must exert on you in order to keep you from moving downward toward the earth’s center. As in most scales, the bathroom scale uses a spring to provide this upward support. If you’re stationary, you’re not accelerating, so your downward weight and the upward force from the spring must cancel…
changed after we put the egg into warm water. The mass of the egg increased to 79.56 grams when it was left in warm water for 15 minutes. After the egg was left for 24 hours in warm water, the mass increased to 85.59 grams. When we put the egg into the corn syrup the next day and let it sit there for 15 minutes, the weight of the egg decreased to 80.94 grams. The mass of the egg drastically changed when it was left in the corn syrup for 24 hours. The mass of the egg went from 80.94 grams to…
Introduction This case study report is to outline the process of planning an activity in science understanding physical science for a 5 year old child with the expectation of learning the concept of motion, inertia, force, velocity, acceleration and gravity by using balls, blocks and tubes. The report will also outline the pedagogy approach adopted by educators to ascertain that the child will engage in a physical science activity, which will improve the child’s skills of problem solving,…
the investigation is incorrect and that momentum was not conserved. Results show that the momentum has increased; this is due to an increase in the mass, from 0.85 to 2.85. The velocity decreased from 0.59 to 0.44. Although the velocity decreased the momentum mainly increased because of the increase in mass. Body A and B, together had a greater mass than body A alone. Trial 3 also showed deviation from the previous two trials. The velocity before the collision was 0.26m.s-1 and was 0.7m.s-1…
Measurement of Static and Kinetic Friction Forces between Wood and a Table Purpose: In this experiment, a spring scale will help calculate the static friction and kinetic friction between a wooden block and table. Several factors impact the amounts of friction, and this experiment examines the factors and how they impact the sliding of the wooden blocks. Surface area of the blocks affect the friction, and the contact between the different surfaces varies for different objects and weights.…
Now on the other hand, using the triangle inequality and then (33) we have ∥u − uh∥ L1(Ω) ≥ ∥uI − uh∥ L1(Ω) − ∥u − uI∥ L1(Ω) ≥ ∥uI − Tpuh∥ L1(Ω) − ∥uh − Tpuh∥ L1(Ω) − ∥u − uI∥ L1(Ω) ≥ ∥uI − Tpuh∥ L1(Ω) − ∥uh − Tpuh∥ L1(Ω) − C2hp+1|u| Wp+1 1 (Ω); ≥ ∥uI − Tpuh∥ L1(Ω) − C∥u − uh∥ L1(Ω) − −C3hp+1|u| Wp+1 1 (Ω); from which we conclude that ∥u − uh∥ L1(Ω) ≥ C0∥uI − Tpuh∥ L1(Ω) − C3hp+1|u| Wp+1 1 (Ω) ≥ C0 vuut ΣN i=1 ∥uI − Tpuh∥2 L1(Ω∗ i ) − C3hp+1|u| Wp+1 1 (Ω)(36) ; where Ω∗ i is as in the proof of…
Part #1.- Adian and I created a carrier for two Ping-Pong balls that look like pair of glasses. To make this model we used four rectangular prisms and a cube. We used two long and skinny rectangular prisms to make the two temples of the glasses, and we used two rectangular prisms to make the two lenses. Then, we made a cube to be the bridge of the pair of glasses. We selected these shapes because when put together they resemble a pair of glasses, and we were familiar with the shapes. We also…
Projectile Motion Worksheet A ball rolls off a desk at a speed of 3.0 m/s and lands 0.40 seconds later. How far from the base of the desk does the ball land? How high is the desk? What is the speed and angle of impact? A slingshot is used to launch a stone horizontally from the top of a 20.0 meter cliff. The stone lands 36.0 meters away. At what speed was the stone launched? What is the speed and angle of impact? A ball rolls with a speed of 2.0 m/s across a level table that is 1.0 m…
this experiment, the objectives were to derive an equation for the tension in the string (which had a mass attached and was revolved in a vertical circle motion). In order to complete this, the velocity of the mass would have to be calculated using the measured tension, and this value would then be compared to the expected velocity. The second objective of this experiment was to observe how mass, velocity, and radius affect the tension of the string. These objectives were reached in this…
