Vertical jump Definition and 15 Threads

I've been bothered about this for a while now. As a volleyball player, I am constantly looking for ways to increase my vertical. So, my question is: Will an increase in muscle mass decrease my vertical? On one hand, I am getting stronger and therefore should be able to push harder off the...

I'm an mobile developer. I'm developing system that detects and counts jumps on a trampoline. I will describe in few words the architecture of system. The system consists of a trampoline, three-axis accelerometer attached to the bottom of the trampoline and a smartphone. All communication...

Homework Statement Okay so these are from movies. I am trying to prove them right or wrong using physics. how can I figure out the pounds of force of a vertical jump when I have the: height of the jump = 6 feet Time to reach top = .797 sec Mass of person = 100lbs 2. How can I figure out this...

Hi guys I've a problem calculating the vertical jump from ground reaction force. We tested a person with a force plate, and we got this curve as a result: Homework Equations These are the equations, sorry for the danish language, but just look at the equations and not the text...

Hi, I'm doing some research on developing a physics-based platform game and I want to see how the gameplay will feel if the environment and physics were made to scale as realistically as possible. Since one of the core features of a 2D platformer is jumping, I need some figures on how much...

Ok, so I'm using an arduino with an led matrix and a homemade pressure sensor to figure out the height of a vertical jump and then display the info back. First I get the amount of time between when the person left the board and when they land back on it. I then divide the time in half and use...

Hi If a person jumps(countermovement jump) then there would be 2 impulses that is the 1st impulse would be when person sits down, getting ready to jump and the 2nd impulse would be when he jumps back on to the ground. 1)I want to know the relationship between these 2 impulses. 2) How can we...

Imagine an athelete that weighs 180 pounds (81.6 kg) is able to jump 20" (0.51 meters) vertically. How high could he jump if he were able to decrease his weight to 170 pounds (77.1 kg)? I think the basic idea here is to find out, given the mass, what force is required to reach the specified...

I'm working on a problem that analyzes vertical jump kinetics. I have a data file that has force plate data and corresponding time steps when a person jumped straight up and then landed on a force plate. I also have the vertical distance that the person jumped. I want to calculate: 1. The...

Homework Statement Imagine that you are prospecting for rare metals on a sperical asteroid composed mostly of iron (which density is 7800 kg/m^3). The radius of the asteroid is about 4.5 km. You've left your spaceship in a circular orbit 400 meters above the asteroid's surface and gone down to...

I am a coach for athletes in various sports and have a problem that I can't figure out, but I'm hoping will be easy for someone here. I am looking to determine the height of a vertical jump from some limited information via an accelerometer. The accelerometer is attached near the center of...

Surprisingly, very few humans can jump more than 2 feet (0.6 m) straight up. Solve for the time one spends moving upward in a 2-foot vertical jump. Then double it for the "hang time" - the time one's feet are off the ground. b) Calculate the vertical height of Michael Jordan's jump when he...

Ok :smile: , I had to test my maximum vertical jump. I did three trials and here's what I got: -Maximum standing height (ie without jumping reaching with one hand) = 221.5 cm -Maximum jumping height with one hand (best of three) = 270 cm -Net Height 270-221.5 cm = 48.5 cm, 0.485m My...

Okay, here's the deal: Basketball player Darrell Griffith is on record as attaining a standing vertical jump of 1.2 m (4 ft). (This means that he moved upward by 1.2 m after his feet left the floor.) Griffith weighed 890 N (200 lb). (B) If the time of the part of the jump before his feet...

A Standing Vertical Jump. Basketball player Darrell Griffith is on record as attaining a standing vertical jump of 1.2 m (4 ft). (This means that he moved upward by 1.2 m after his feet left the floor.) Griffith weighed 890 N (200 lb). 1.) Use Newton's laws and the results of part (B) to...
