What energy transformations happen when a person lifts a chair?
Chemical energy from the person's muscles is turned into potential energy.
Explain the role of friction has in the energy transformation of a person skiing downhill?
Friction and air resistance cause some of the mechanical energy of an object to change to thermal energy so the mechanical energy of the object is not destroyed. Rather, it is transformed into thermal energy. the total amount of energy always stays the same. ur welcome. you have to give me 5 bucks.
What energy transformations occur when a person parachutes out of an airplane?
When a person parachutes out of an airplane, the potential energy in the form of the person's gravitational potential energy is converted into kinetic energy as the person falls. When the parachute is deployed, some of the kinetic energy is transformed into air resistance and heat energy due to friction with the air. This allows the person to safely descend to the ground at a slower speed.
What form energy is used when a person pushes a wooden block across the floor?
Friction is produced and kinetic energy is used
What lung sound will you hear in a person with pleural friction?
lung sound in a person with pleural friction
Name two ways heat is produced by a person pedaling a bicycle?
His muscles gets hot as they turn chemical energy into kinetic energy. Kinetic energy turns into heat in the bearings and the brakes on the bike due to friction.
Describe the energy transformations that occur when a person pushes a bike to the top of a hill and coasts down?
First it's chemical energy from eaten food that turns into heat, a little bit of kinetic energy and potential energy(pushing the bike uphill). Then it's potential energy turning into kinetic energy and a little bit of heat, along with some further chemical energy being used up.(coasting down)
What is the difference between friction and gravity?
FRICTION is the energy generated when two bodies have some physical interaction with each other. GRAVITY is the force of a mass which pulls an object towards its center. *Friction produces heat but not Gravity
What are the advantages and disadvantages of having friction in sport?
These are a few of the great many advantages and disadvantages of having friction in sport: Friction allows a running person to stop, change direction, jump, catch a ball, and throw a ball. Friction between a ball and the air limits how far it can be thrown (although gravity has an even greater effect). Runners require energy to overcome the friction between their feet and the ground.
Can a person with two hip replacements still go downhill skiing if they are careful?
possibly,yes!
How does friction affect a person's spin?
Friction slows things down thus the spin of one is slowed.
What can a person do to help prevent blisters?
A person can wear moisture wicking socks which decrease friction. Friction between the foot and the shoe is what creates the blister after running .
