What if a boy eats an apple then lifts weights and sweats what forms does the energy in food transform to?
From chemical energy to mechanical energy and heat energy.
How can mechanical energy can be converted into electricity?
That is what an electric motor does. A relay also does this, as does a big lifting electromagnet in a junkyard.
Why is stretching different from lifting weights?
Because lifting weights requires actual weights it puts resistance on the muscles to make them stronger bigger and more durable unlike stretching, these two are completely different from each other.
A mechanical device requires 420 j of work to do 230 j of work in lifting a crate what is the efficiency of the device?
The efficiency is (output energy)/(input energy) = 340/400 = 85%
Can an object have both mechanical and kinetic energy?
If an object has kinetic energy, then almost BY DEFINITION it has mechanical energy. "Mechanical energy" is the sum of kinetic energy and potential energy.
Mechanical energy examples?
Riding a bike, running, lifting weights
Discuss the production and dissipation of mechanical energy in a lifting weight holding up lowering the weight slowly?
1: Humans intake chemical energy in the form of food 2. when blood flows in to the tissues, energy and heat is released in tissues. 3. when lifting weights, this energy is used to perform work(lifting weights) and some amount is also lost as heat. 4.When weights are lifted, the energy is stored as potential energy. 5.when weights are lowered, muscles do work against gravity..this energy is used to increase the temp of muscles, part of it results in muscle wear.
What following constitutes a good anaerobic workout?
Lifting weights
Can lifting weights be an exercise?
Lifting weights is an exercise
What does Lifting an ax higher when chopping wood adds to the of the ax?
potential mechanical energy
What if a boy eats an apple then lifts weights and sweats what forms does the energy in food transform to?
From chemical energy to mechanical energy and heat energy.
What is the subject and predicate of Lifting weights builds muscles?
Lifting weights = subject builds muscles = predicate
What does lifting free weights mean?
it just means lifting weights that is not on a machine like using a curl bar
What describes the energy transformation that takes place when a boy eats an apple and then lifts weights?
Chemical energy is converted to mechanical and heat energy
Do you get fat if you quit lifting weights?
This answer depends on your diet. If you continue to consume the same amount of calories after you quit lifting, then yes you may get fat. Lifting weights burns calories and muscles need these calories to build more muscle. If you quit lifting weights, your body no longer needs as many calories. Also, your metabolism will slow after you quit lifting weights. Now, if you quit lifting weights and also cut calories, you will not get fat.
Can a person lifting a weight be chemical energy to mechanical energy or a dark light bulb starting to glow or food being heated in an oven or a ball rolling down a hill?
Lifting wieghts
What is the kinesthetic effect?
it's the feeling you get after lifting weights where everything feels lighter and werid. not only after lifting weights but also putting leg weights on etc.
