Most of your weight is on your toes so you’re ready to push forward when hitting the ball. When you are in the correct position you have to create a platform with your arms by putting them together. You have to clutch your hands together so your palms are facing the roof and your arms in a relaxed position. As the ball is in motion coming towards you, calculate how much force needs to be applied to get it to the setter. As you push through with your legs, you use the momentum of your body to push through the ball with your arms getting the ball up high enough for the setter to get into position and execute the next pass.
The object of the vertical jump is to get up in the air by exerting as much force against the earth’s surface to gain a greater reaction from the earth (Carr, 2004). The countermovement vertical jump is a non-repetitive skill that does not always have a discrete beginning point due to environmental conditions; however, it does always have a discrete end point. For example, during a volleyball game the blocker has to position himself in relation to the opposing hitter, and respond to the direction of the hit. The countermovement vertical jump is a force producing skill that not only generates force throughout the legs
It is your preference whether you focus on the front of the basket, the back of the basket, an imaginary pair of lines leading upward from the side edges of the basket, the oval inside the basket, or another point of visual focus. The important thing is to be consistent with the one you use unless there is reason to change. The way you hold the basketball is also a very important step. Your hands should hold the basketball firmly enough to give you control of the basketball. As your arms raise the basketball, your shooting hand and it's elbow should move under the basketball.
In addition, the initial and final velocities due to the short range setting were smaller in comparison to the initial and final velocities due to the short range setting. Since no external forces are acting at the instant of the collision, momentum for these inelastic collisions is conserved. However, the kinetic energy loss was almost the same for both settings-96.1% for short range, 99.2% for long range). This is because kinetic energy is not conserved in inelastic collisions. Discussion: In this experiment, a spring trigger launches a steel ball, acquiring a certain initial velocity.
When a punch is thrown a boxer will remain in a balanced position. At the point of contact, the punch delivers a force that will knock their opponent off balance. The head, neck, or even the whole body can be moved with the force of a punch. Newton's second law is best stated with the equation F=ma. F stands for the net force acting on that body, m for the mass, and “a” for the acceleration of the body.
Once the results are found you can calculate the percent error of the uncertainty values. The uncertainty value is the acceleration of the ball falling down. That value will be compared to the gravity value to see how closely related they are. Introduction The formal lab “Uniform Acceleration”, studies uniform acceleration by rolling a ball down a ramp and dropping an object to calculate its acceleration. Also this lab teaches about measurement uncertainty can be calculated using the percent error equation.
Basketball: The Work Everyday Basketball player’s code: jumping, running, and shooting is what you need to be an efficient basketball player. Jumping; what goes into being able to jump and not be tired during a game? Running; how do you have enough endurance for a game? Shooting: how do you make yourself unstoppable? All this put together to make an unstoppable basketball player.
“K = ½mv2 where K = kinetic energy” (Koehler, J., The Science of Pocket Billiards) When you strike another ball with the cue ball it is almost a perfect elastic collision. An elastic collision is one in which total kinetic energy as well as total momentums are conserved within the system. This can be shown by the two basic equations; Conservation of “Kinetic Energy: ½m1v1i2 + ½m2v2i2 = ½m1v1f2 + ½m2v2f2 Conservation of Momentum: m1v1i + m2v2i = m1v1f + m2v2f where m = mass of object v = velocity” (Koehler, J., The Science of Pocket Billiard) Since the cue ball has virtually the same mass as the other balls and the velocity of our second ball will always be zero, since we are striking a static ball with the cue ball. In addition this is considered a two- dimensional collision. From this we know that momentum is saved within the y component and within the x component.
2. Answer: To see when a certain material of a ball is rolled from a certain angle at the various cm. It is also to see how the object picks up momentum. Also to see the distance of the cup when a objects weight will move the cup from the starting point. (3 points) |Score | | | 3.
The number of points the team gets depends on the points per base, or the batter getting a home run. In basketball, players shoot the basketball into the hoop on their team’s side of the court. The number of points scored depends on the shot
