How does friction affect a javelin?
It will have to be making a forward force on the ground through friction, as well as a downward force on the ground. The forward horizontal force made on the ground through friction (dragging) will make the ground exert, by reaction, a backward reaction force on the foot (see figure 2).
How is friction used in netball?
In Netball, friction is a beneficial force. Friction prevents netball players slipping, sliding and stepping, if a player does step then the other team will get the ball so this is a big component in a game.
How is friction involved in basketball?
Friction is helpful to the game of basketball. It enables players to stop quickly and start running in the opposite direction. Without friction players would slide uncontrollably around the court when they tried to stop running.
What affects the flight path of a javelin?
The flight path and distance of the javelin depends on the angle of attack, which is the difference between the: angle of attitude: the orientation of the javelin to the ground. angle of velocity vector: the flight path of the javelin’s centre of mass (not the tip).
What makes a good javelin?
To be a javelin thrower, one needs a good throwing arm; to become a great javelin thrower, one needs to use the entire body. To throw really far, athletes need to become fitter, more flexible and increase their event-specific strength through the entire throwing range of motion.
Does a javelin have a parabolic flight path?
A projectile is anybody which is thrown or jumped into the air. Once it has left the ground it will follow a flight path called a parabola until it once more comes back down to earth. This applies to balls, javelins, discus, long jumpers, high jumpers, and horses showjumping.
What flight path does a javelin have?
For most objects the optimal flight angle is 45 degrees. Do to the javelin’s aerodynamics and speed its release angle should be around 36-40 degrees. This is calculated from the path of the javelin’s center of gravity.
How fast does a javelin travel?
At release, a javelin can reach speeds approaching 113 km/h (70 mph). The javelin throw consists of three separate phases: the run-up, the transition, and the delivery.
What is the best javelin grip?
Fork or “V” Grip Fork grip is great for those new to javelin. The javelin is held across the palm of the throwing hand, with the top of the cord resting between the index and middle finger.
