A person parachuting from a plane has already acquired potential energy by rising to whatever altitude the plane is at-this energy has been obtained from the fuel used by the plane. This energy is then turned into kinetic energy as a result of the earth's gravitational attraction, and the parachutist goes into freefall. Braking the speed of fall to make a safe landing, the kinetic energy is returned to the air which is slowing the parachute. The net change when the person lands is zero.

What energy transformations in a person running?
When a person is running, the chemical energy stored in their muscles is converted to mechanical energy to move their body. Some of this energy is also converted to heat due to muscle movement and friction with the ground.
What energy tranformations occur in ringing bell?
When a bell is rung, mechanical energy from the person ringing the bell is transferred to the bell causing it to vibrate. The vibration of the bell produces sound energy as it moves through the air, creating the ringing sound. So, the energy transformations involved are from mechanical energy to sound energy.
What are the energy transformations of a slingshot?
When a slingshot is pulled back, the energy used comes from the person's muscles (kinetic energy is transformed into potential energy). When the slingshot is released, the potential energy is converted into kinetic energy in the slingshot and projectile. Finally, when the projectile is in motion, some of the energy is lost as heat due to air resistance and friction.
How was energy transformed to another form?
Energy can be transformed from one form to another through various processes such as combustion (chemical to thermal), a generator converting mechanical energy to electrical energy, or a person converting chemical energy from food to mechanical energy while exercising. These transformations follow the principle of conservation of energy, which states that energy cannot be created or destroyed, only changed from one form to another.
What type of energy is a person lifting a chair?
The energy used by a person to lift a chair is mechanical energy. This energy is converted from the chemical energy stored in the person's muscles to the kinetic energy of the chair and the person as they perform the lifting action.
What energy transformations happen when a person lifts a chair?
Chemical energy from the person's muscles is turned into potential energy.

What role does friction have in the energy transformations of a person skiing downhill?
Friction plays a crucial role in the energy transformations of a person skiing downhill by converting some of the skier's kinetic energy into thermal energy. As the skis glide over the snow, friction between the skis and the snow surface generates heat, which can slow the skier down. While this energy loss can reduce speed, it also helps control the skier's descent, allowing for maneuverability and stability. Overall, friction is essential for balancing speed and control while skiing.

How many people do you need to build an airplane?
A single person can build an airplane.
What is the coolest airplane?
This answer will vary from person to person, but I always thought the Pilatus PC-6 "Porter" was a very cool airplane.
How do we call person fly airplane?
The person who flies an airplane is called a "pilot". Sometimes, they are assisted by a "co-pilot" and/or a "navigator".
