Inelastic collisions occur when the kinetic energy of an object is not conserved, but converted into other forms of energy, such as heat or potential energy. As such, they still obey the conservation of energy principle that energy cannot be created or destroyed. When two bodies undergo an inelastic collision, their combined initial kinetic energy is not equal to the final kinetic energy of the system. When a tennis ball bounces on the ground, the kinetic energy that the ball possesses just…
The differences between barefoot and shod running
Humans have the ability to perform various movements, such as jumping, walking, running, etc. However, tend not to think the essentials of movement as they are not applying the mechanisms that allow them to move from one place to another. The amount of energy required to walk at a comfortable place is very small in comparison with other activities (Everett and Kell, 2010). The study of De Wit et al, (2000) concluded that,…
Critical analyze of the role of third Druk Gyalpo Jigme Dorji Wangchuk in the process of Democratization
Bhutan is a small landlocked country which has been remain isolated for decades and left backward, unrecognized and never known to the outside world. However, after Wangchuk dynastic and hereditary monarchy came into existence with Jigme Dorji Wangchuk as third hereditary monarch of Bhutan who was being born to Azhi Phuntsho Choden and second king Jigme Wangchuk at Thruepang Palace (Trongsa)…
II. 2. Hydraulic Jump
1. to create/generate hydraulic jump
2. To clarify questions about the fluid flow.
3. To determine the slatrility and characteristics of hydraulic jump, performed in the laboratory using impulse momentum and energy equations are specific.
4. to compare between the depth of flow measurements and the results of the theory.
2.2.2. Basic Theory
A hydraulic jump occurs when the flow of the flow at a high speed exposure at a low-speed flow that occurs at the…
1. Derive the mathematical expression for the Lorentz transformation equation.
relative orientation of the co-ordinate systems indicated in fig.2
A light-signal, which is proceeding along the positive axis of x, is transmitted according to the equation :
x - ct = 0 _______ (1).
Since the same light-signal has to be transmitted relative to K1 with the velocity c, the propagation relative to the system K1 will be represented by the analogous formula
x' - ct' = 0 _______(2)
How do speedometers work?
A: A speedometer is a gauge that measures the instantaneous speed of a vehicle. Speedometers became standard in all motor vehicles in 1910
Speedometers were created by the Croatian engineer Josip Belušić in 1855
Uses the rotation of the wheels to work
When the cars engine turns over the drive shaft spins to turn the wheels
The speedometer cable which is powered by the driveshaft also spins
A magnet located inside the speed cup (made of aluminum) of the car spins at the…
Lab 3: Technology
Section: General Physic Lab 3
The goal of this experiment was to learn how to apply computerized instruments in physics. In addition, this experiment aimed at enhancing practice on how to use three equipment in the lab: the rotary motion sensor, high resolution force sensor, and motion sensor. Further, this experiment sought to clarify the circumstances under which the instruments fail to comply with expectations.
Part 1: The…
Introduction: The purpose of this lab is to help students gain a better understanding of physical concepts such as work (which occurs when an applied force moves an object.) torque (defined as a twisting force), energy and rotational inertia (an object's resistance to rotation).
Experimental Design: My group’s testable question throughout the mousetrap car experiment was: If we add and subtract factors such as material, weight and shape, from the wheels of our car, how will it affect the…
Why did you lock up Isaac Newton?he didn’t do anything wrong he just creating a new math discovery called calculus.what is his backstory?how did he create this?,or why would he create this?
You may be wondering about Isaac Newton’s backstory?well I tell you how it all went down.Isaac Newton was born december 25,1642 Woolsthorpe,Lincolnshire.He was born only with a mother and a step father ,since his father had died before he was born.Then he was three his mother left him with her grandma when…
Projectiles, such as the ones shot from cannons, are affected by drag or air resistance. The amount of drag exerted on to an object is affected by many different factors, such as air density and the size of the projectile. It is important to understand drag, as it affects the distance an object is able to travel if it is not influenced by outside forces, such as a cannons projectile. The equation for drag is shown below.
p = The density of the air.
C = The drag coefficient of the…
