Mass versus weight

Proportionality and Newton’s Second Law of Motion Abstract How does increasing the mass of an object affect its acceleration? Is acceleration dependent of the mass of an object? How do they relate? Defining and testing Newton’s second law of motion familiarizes us with this relationship. In this experiment, we use the mass of an object as an independent variable to come to a conclusion about force and acceleration. By increasing the mass of an object at an incline, one can observe the change in…

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…

Have you ever seen someone dive off the diving board? Do you enjoy swimming? Well now I’m going to give you a little more information on swimming and what the physics of it is. You will see swimming in a whole different way. Gravity is always affecting you while swimming. Even you don’t think it is. Force of attraction by which terrestrial bodies fall toward the center of the earth. Newton’s first law of motion has a part to do with swimming. An object in motion stays in motion until another…

Spring Scales People quantifying the material in an object by measuring its weight. Spring scales eventually became one of the simplest and most practical tools for accomplishing this task, and they are still found in bathrooms and grocery stores. These 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 weight 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…

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…

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. Kinetic friction occurs when two objects move against each other with their surfaces in contact, and the normal force helps calculate kinetic friction. Static friction is the force which must be overcoming to originally start moving an object.…

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…
