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…

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,…

Newton’s third law (If body A exerts a force on body B, body B will exert an equal force but opposite force on body A). Thus when objects collide or explode apart, equal forces are exerted on the objects but in the opposite direction. The time of which the forces are in contact with the object is the same for both objects therefore if one object loses momentum the other object must gain an equal amount of momentum. An isolated system is one which the only forces are between the bodies that are…

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…

We think that the lighter the rocket, the better it will fly. The mass of a rocket definitely can affect flight time. We can manipulate the amount of paper we put in the head of the rocket to make it heavier or lighter, and we can change how much tape we use to put the rocket together. We want the rocket to glide better…
