Gravity and elastic force.
When bungee jumping, people go head first because the bungee cord is attached to their feet, and if they reamined in an upright position until they reached the end of the cord, it would flip them upside down with a very large amount of force. This would create a painful whiplash and greatly increase the risk of injury to the jumper, especially in to their spine.
No, a bungee cord cannot be used as a force meter because the elasticity of a bungee cord is not that much, compared to a force meter.
The rope stretching during a bungee jump helps to absorb and dampen the jumper's kinetic energy, reducing the impact force on the body when they reach the bottom of the jump. This stretching process also allows for a smoother deceleration, which is crucial for the jumper's safety and comfort.
yes, stretching is a force!
Bungee jumpers use ropes with small force constants because they need the rope to stretch and absorb the energy of their fall gradually, rather than stopping them suddenly. A smaller force constant allows for a longer period of deceleration, which reduces the stress on the body during the jump.
Gravity, rope, and friction
A stretching force, also known as tension, is a force that elongates or stretches an object. A pulling force is a force exerted on an object to move it towards the direction of the force. Both forces involve pulling or stretching an object.
A stretching force is called tension. It is a force that pulls or elongates an object without changing its shape.
