SCIENTIFIC REPORT PROFORMA YEAR 8 Task 1 2018 Student name: Jacob Teacher: Miss Bianchi Class: 8.5 Due: Tuesday 27th March 2018 TITLE: Bouncing Balls BACKGROUND RESEARCH: Physics: is the main part of science involved with the character and properties of matter and energy. Matter of physics includes: mechanics, heat, light-weight and alternative radiation, sound, electricity, magnetism, and also the structure of atoms. Physics has many things that help us or things we use and we…

Long Jump Procedures: The participant has to stand behind the line and has to jump off of both feet and attempt to jump as far as possible while landing on both feet. The participant gets three chances to jump as far as they can, then they record their data. Advantages: This test does not take very long to do and it does not require a lot of equipment. Disadvantages: It takes some form to know how to do this properly so some participants may have an advantage over others. Validity: it is a good…

Two factors are required for proper operation of a gas turbine. One is expressed by Newton’s third law. The other is the convergent-divergent process. Convergent means approaching nearer together, as the inner walls of a tube that is constricted. Divergent means moving away from each other, as the inner walls of a tube that flares outward. Bernoulli’s principle is used in this process. The venturi of the common automobile carburetor is a common example of Bernoulli’s principle and the…

“Bicycle, bicycle, bicycle. I want to ride my bicycle, bicycle, bicycle. I want to ride my bicycle. I want to ride my bike.” High pitched in all its glory—at the top of our lungs—it was “Bicycle Race” by Queen, or The Bicycle Song in the terms of an unknowing five-year-old. It started my morning for three years. Katherina would rock out to and sing this memorable song, even through its fiftieth time, with a joy that few siblings can muster. Sometimes loud, sometimes in a fit of giggles, but…

Objective: The lab we completed today was “Equilibrium of coplanar forces”. The objectives of todays lab was to study the composition and equilibrium as well as study the rectangular resolution and equilibrium of coplanar forces. Principles being examined: The main principle being examined in this experiment is the fact that several forces that line on a plane and pass through the same point can be balanced by a single force that is passing through the same point. We do this by finding the…

Asana. Now raise whole body towards sky in such a way that that only shoulder and head is on the ground .  While inverting yourself balance your raised body with the help of your hands holding the back with bent elbows on the the floor ,making broad base for supporting upright straight body.  Try to keep raised part of body straight as shown in picture.  During this maintain normal breathing and stay in the posture for a while.  Now slowly slowly bring down raised part of body on the…

Determining the effect of the mass on the drop time of a parachute Introduction and hypothesis The drop time of a parachute is dependent on multiple factors. Apart from mass, there is the obvious height, area of the parachute and other external factors such as wind. Mass is one of the main effectors of the drop time of a parachute, which can be proven through Newton’s second law, F=ma (Force=mass*acceleration). Rearranged, this gives a=F/m, where acceleration can also be gravity, if falling down…

air’s mass density are the factors that directly affect the drag force as they will affect the wave drag and skin friction stated above. Thus, to minimize the drag force, the aircraft is made to be more streamlined and the wings are narrower. The material used to make aircraft also need to have smooth surface. These are because the shape, size and surface roughness of the object will affect the drag. As these conditions decrease, the drag will…

In the chapter Kinematics of Particles, we studied about various relations among time, position, velocity and acceleration of a particle. When we have a relation between any two parameters, we can calculate remaining parameters. In Kinetics of Particles, we applied Newton’s second law of motion ƩF = ma. The fundamental concept is when external forces acting on a particle are balanced (zero resultant), the particle will be in equilibrium. But when external forces acting on a particle are not…

velocity changes. The equation for acceleration is: a=∆v/∆t in which the variable a represents acceleration, ∆v represents the change in velocity, and ∆t represents the time interval. In addition, gravity is the force that attracts a body towards any physical body that has mass. Galileo Galilei discovered that the distance a standard accelerating object travels is proportional to the square of the…
