Trampoline By Hooke: The Equation Of Temp

520 Words3 Pages

A trampoline is a piece of that you jump on to have fun. The physics in jumping on a trampoline is Newton's 2nd and 3rd laws, Hooke’s Law, kinetic energy and Gravitational and Elastic potential energy.

Hooke’s law is similar to Newton’s third law, it states that for a spring to stretch an x amount of distance an x amount of force has to be applied to it. The equation, Fspring=-kx shows this linear relationship (The force a spring can exert is equal to negative the spring constant multiplied by the displacement of the bobject on the spring). What this means is if you jump harder on the trampoline, you will go higher because you are applying more force onto the springs which will cause the springs to push back that force towards you.

When someone jumps (by adding force) on the trampoline, the trampoline pushes them out and gravity brings them back down. By doing this the trampoline is pushing the person to their equilibrium, where there is 0 elastic potential, and the force of gravity is the restoring force that brings them back to the equilibrium point. …show more content…

This is calculated by the equation PE=½ kx2. In this equation, x is how far the springs can go and k is the spring. This concept also ties in with Newton's 3rd of motion, “every action has an equal and opposite reaction”. In order to start jumping on the trampoline and for the elastic potential to build up, there has to be a force applied to the springs. The action of applying force onto the trampoline to bounce creates the equal and opposite reaction of the springs going down, which causes you to jump. The more force you apply on the trampoline the lower springs go and the higher you

Information from the flow chart created in Activity 2.2.1 might be helpful. For the voluntary activation, the acceleration was higher ranging from numbers in the sevens to numbers in the fours. The voluntary reflex is manually kicking when you hear something or come in contact with your knee. The involuntary reflex is an automatic process that your body goes through when it comes in contact with a specific spot. The body must go through something for each reaction to occur.

Physics was observed during a DHS girls lacrosse game by Newton’s Laws and in free-fall. Newton’s Laws consist of 3 different laws, the law of inertia, F=ma, and action-reaction forces. Free-fall was observed in the game when the lacrosse ball falls, and only gravity acts upon it. All in all, Newton’s Laws and free-fall was portrayed during the lacrosse game.

Chapter 4 Elasticity What is elasticity? Elasticity means the ability of an object to resume its normal shape after being stretched, or the ability of something to change and adapt. Some examples of elasticity is a bungie cord and rubber bands. Then there things that can be the opposite of elastic; which is called inelastic.

However, they may have different amounts of it when they both bounce because of the way they are made. One’s rubber may be stretched or compressed in a way that gives it more elasticity or bounce so that when it hits the racquet or court it bounces higher. Tennis balls have less elastic energy than golf balls so one may think they have less elastic potential energy than racquetballs on average. Also, with the tennis ball weighing more and still having enough elastic energy to bounce as high as the lighter racquetball it is right to say that the tennis ball has more elastic potential energy. Finally, gravitational energy is the last main type of energy that affects tennis.

For this experiment, I used the online Mass & Springs PhET simulator to perform the experiment. First, I positioned the ruler so that 0 was on the line at which the end of the spring was at rest. Then, I put a 50g weight on the end of the spring and let the spring come to rest. After that, I pulled the spring down 10cm and released. I recorded the point at which the spring’s rebound stopped.

Without the spring floor, gymnasts cannot excel. This affects two of the four events in gymnastics: floor and beam. The spring floor allows gymnasts to perfect and advance skills, which directly results in higher scores at competitions. On top of that, a new skill on the balance beam is rare, for a spring floor is where the skill starts in an adolescent phase and it progresses to the beam only when it is flawlessly performed on the floor. Therefore, the potential of these athletes cannot be reached because the gymnasts rarely get to practice on the spring floor.

The stored elastic energy contributes to force production by storing energy in the series elastic component, if you quickly produce a concentric force after an eccentric force. This will result in a more forceful contraction (Joao and Veloso, 2013). The involuntary contraction of the muscle spindle during a rapid stretch causes a greater recruitment of muscle fibers, which adds for a more forceful contraction because of the stretch reflex. 2.

Roller Coaster Project Report

As the marble slides down the first drop it will lose much of its potential energy corresponding to the loss of height. The marble subsequently gains kinetic energy – kinetic energy is contingent to the mass and the velocity of an object. The marble speeds up as it loses height, consequently, their potential energy is transformed into kinetic energy. Newton’s Second Law states that an object’s net external force is equal to its mass times its acceleration; simply, the acceleration is proportional to the force applied and also the mass of the object.

How Do Different Surfaces Affect How High A Basketball Bounces

When the ball hits the ground its kinetic energy is turned into elastic energy this makes the ball flatten out. Then that elastic energy is converted right back into kinetic energy when it goes up. So the more kinetic energy a ball gets when it is dropped the more energy it will have when it hits the ground which will give it more energy when it is headed back up therefore making it bounce higher.

The more mass an object has, the greater its gravitational pull. This applies to momentum as well, more mass = more momentum. Doubling an object’s mass will double its momentum and gravitational pull as well, so dancers with different masses will be able to jump or leap at the same height. For my experiment, I decided to put the things I learned about momentum in the dance studio.
