Case Study: Ping Ping Ball Launcher

Independent: • Mass of each of the balls will not change after various trials Dependent: • Time it takes for the ball to hit the ground might be different after each trial Controlled: • Height at which ball is dropped • Ball dropped at rest/initial speed   Method/Procedure: 1. Support 1m ruler vertically against the wall 2. Hold ball at 1m high from the ground at the top of the ruler 3. Start the timer at the instant the ball is released from your hands (make sure stopwatch is zeroed before each trial) 4.

Physics Lab Report Name – Shaurya A Singhal I.D – 13229 Grade – 12 Investigating the effect of the angle of incidence on the diameter of a Crater formed by a falling object Introduction When a bob is dropped into sand, a circular crater is formed due to the impact of the ball. The size of the crater varies with numerous factors, Mass of falling object Angle of incidence Velocity of object Rigidity and Tensile Strength of surface on which object falls Background Theory

One scientific theory related to this experiment is the Magnus Effect. The Magnus Effect is in action when the ball is pushed from high to low pressure, which makes it curve (The Physics of Kicking a Soccer Ball). During the Magnus Effect, the passing air is moving the same direction as the surface of contact on one side of the ball. Since the person in this experiment kicked with their left foot, the ball curved to the right a little because the air moved over the ball faster on the left side, causing less pressure on the other side of the ball. All of this air movement is what makes the ball slant in a different direction.

Construction Challenge #4 Explain what the challenge was… The challenge was to make, with your team, a 30 inch cantilever beam with 16 plastic straw, 5 of the straw wrappers, and 15 centimeters of tape. Each team was allowed to use scissors and a hole punch to put together the straws. Then, Mr. Milhous placed the beam 24 inches off the table 6 inches on the table.

This is because vectors can be used to describe things with magnitude and direction. A volleyball's displacement has both of magnitude (distance) and direction. The arms extended out can be modeled as planes, and by looking at how different angles affect the rebound trajectory of the volleyball, I can manipulate the angle of the plane in relation to the bumper to get the right direction of reflection towards the setter. The Problem How do I angle myself in relation to the setter when bumping a spike?

At long distances, two nuclei repel each other due to the positive protons and the electrostatic force. However, if two nuclei were to be brought close enough the electrostatic repulsion can be overcome by the attractive force of the nuclear force, which becomes stronger at nearer distances. In the diagram below, the electrostatic force between the positively charged nuclei is repulsive, but when the separation is small enough, the attractive nuclear forces is stronger. As a result, the requirement for fusion reaction to occur is that the two nuclei are brought close together for enough time for the nuclear force to

Hot Air Balloon Analysis In the duration of this project there were many factors that needed to be kept into consideration. The most important was the laws of gas, because the hot air balloon needed to be be constructed enough to withstand the air and have enough room for the hot air particles to move making the balloon have a successful flight. Due to the hot air particles move as a faster rate making then collide to each other which causes the balloon to have enough energy to take flight. While actually launching the ballon I began to see the balloon that did take flight and those who did not.

When two cosmic strings are pulled together, it is possible to distort space-time creating Closed time-like curve, wherein the space and time returns exactly the same as it was in the past. The interaction between two cosmic strings could propel itself into the past it will bend around the cosmic strings. In simple words, as stated by the theory of relativity, once the cosmic string moves in a light speed, time will drift slower for the cosmic string relative to its surroundings. A closed loop of cosmic string drifts in a more standard way. Since the universe is expanding, the cosmic string also forms a loops and their gravity is the responsible in making a galantic supercluster.

Therefore, the object is accelerating and this acceleration is known as centripetal acceleration (ac=v²/r, ac is centripetal acceleration, v is velocity and r is radius). Centripetal acceleration also have another name, G-force, are due to two factors one is the speed of the carriage and the other is the radius of the circle (how curved the track is). This acceleration is due to the unbalanced force called centripetal force (Fc=mv²/r, where Fc is centripetal force, m is mass, v is velocity and r is radius). Greater speed will result in a greater acceleration and therefore a greater net force, on the other hand smaller radius means a smaller acceleration and net force required. Both centripetal force and centripetal acceleration are towards the centre of the

The most violent shocks and subsequent destruction is caused by the L

Furthermore, the explosion of the firework isn’t the only occasion for the sound. For example, when you shoot certain rockets you’ll here the whistling sound as the firework goes up and then a bang as it explodes.

“Does the Mass of a Ball affect its bounce.” Yes mass does affect how high a ball will bounce. It does because the more mass a ball has the more kinetic energy it gets due to gravity. When the ball hits the ground its kinetic energy is turned into elastic energy and the more kinetic energy there is the when the ball is bounced the more kinetic energy it will have going back up.

The answer would be no. There cannot be a vertical motion of air possible with hydrostatic equilibrium because the gravitational force is balancing it out and without the force of gravity, the pressure gradient force would make the air accelerate into outer space. Furthermore, without the pressure gradient force, the gravity could cause Earth’s atmosphere to

Mega straws are two straws taped, the mega straws go on each edge of the pyramid. The genius behind this amazing design that came from my mind, is when it falls it will land. Without the egg (which is inside the pyramid) touching the ground, the straws are purposefully long for just that reason. The other great thing about it is, the straws go beside the egg, not directly pointing at the egg. Which means when the straws hit the ground the energy will go up through the straws, and not into the egg.

Many useful portions in this article that provide information about the catapult was found. There is information about what types of catapults there are and how they all function. This article tells how far a catapult from the medieval time could launch, which is a much larger scale than the ones that are built today. There is a lot more information about a catapult on this article that states how the catapult uses energy to launch projectiles at such a fast rate.
