Hi there, would someone be able to tell me if this is right or almost right or really not right?!
The scenario being explaining the transfers and conversions of energy of a diver. from walking up the steps to standing at the top of platform to jumping into pool and to start swimming.
So i have - CHEMICAL -INTERNAL & KINETIC - POTENTIAL & GRAVITATIONAL
(transfered from body to steps then once reached the top of steps)
POTENTIAL & GRAVITATIONAL - CHEMICAL - KINETIC & GRAVITATIONAL - SOUND&HEAT
( From board to a dive into the pool and on entrance to the pool)
CHEMICAL - KINETIC& HEAT & SOUND
(whilst swimming)
Thank you
It is hard to tell, there is so little explaination of your terms. If I were your teacher, I would mark it as inadequate.
I am trying to gain a understanding of the transfers and conversions of energy whilst the subject (being a diver) goes through its motions.
Maybe i should be clearer ....
SO as the diver makes his way to the top of the steps chemical energy is transferred from the body to the steps(unsure of transfer) Work? converting into kinetic energy. as the diver reaches the top of the steps the kinetic energy converts to potential and gravitational energy?
From the board chemical energy converts to kinetic and gravitational and on entrance to the water sound energy? as the diver starts to swim chemical energy converts to kinetic and internal energy and sound as the diver swims through the water?
from the body to gravitational potenial energy by moving up the steps. At the top, his new larger GPE is released when diving, and is converted to KE on the way down. When he hits, the KE is converted to sound and frictional heat. As she starts to swim, body chemical energy is converted to work by arms moving water backwards, giving a forward motion to the swimmer. The work being done is mostly converted to friction in the water, but some of it becomes swimmer KE.
but kinetic is used to get to the top of the steps?
There is some kinetic energy, but most of the body's work is going into GPE. One does not move very quickly up steps, but I admit, some of the energy is going into kinetic energy.
Ok thanks, so the transfer of energy is work done by the body?
to clarify ...
As the diver walks up the steps chemical energy is transferd through work and converts into GPE and kinetic energy.
what is the energy transfer to begin the dive? chemical? once the dive has begun GPE is converted into kinetic and on entering the pool sound and internal energy . chemical energy starts the process of swimming and kinetic and internal energy are then present?
Based on the scenario you described, let's break down the transfers and conversions of energy for a diver:
1. Walking up the steps to standing at the top of the platform:
- The energy transfer starts with chemical energy stored in the diver's body.
- This chemical energy is converted to internal energy and kinetic energy as the diver moves their muscles to ascend the steps.
- Additionally, there is potential energy and gravitational energy involved as the diver moves upward against the force of gravity.
2. Jumping into the pool and starting to swim:
- As the diver jumps off the platform, there is a conversion of potential energy and gravitational energy into kinetic energy and gravitational energy.
- At the same time, there is also a conversion of chemical energy as the diver propels themselves forward during the dive.
3. Swimming:
- Once in the water, the main source of energy for the diver's movement is chemical energy stored in the muscles.
- This chemical energy is converted into kinetic energy, allowing the diver to move through the water.
- Some of the chemical energy is also converted into heat energy due to the body's metabolic processes and friction with the water.
- Additionally, as the diver moves through the water, sound energy is produced through splashes and movements.
Overall, your understanding of the transfers and conversions of energy for a diver seems to be mostly correct. The main points to note are the involvement of gravitational energy, the conversion of chemical energy during the dive, and the additional conversion of heat, sound, and kinetic energy while swimming.
