Why are you doing work when you lift something but not when you carry it?
Its just due to the "physical" definition of work. In order for a force to do work on an object it must move (at least some component of it) parallel to the force. So when lifting, the force is up and the movement is up and the force does work. In carrying, the force is up but the movement is horizontal. They are perpendicular and the force does no work. False
What are the two main types of forehead lifts?
The classic, or open, forehead lift involves a long incision along the top of the forehead and lifting of the skin of the forehead. The second type of forehead lift, known as an endoscopic lift, is performed with special instruments
Are weightlifter lifting dumbbells balanced or unbalanced?
No
How do you measure weight of lifting object?
By NEWTONS.
What is The slowest type of mass movement which involves the lifting and contracting of soil particles over time is call?
creep
The slowest type of mass movement which involves the lifting and contracting of soil particles over time is called?
Creep is the slowest type of mass movement that involves the gradual lifting and contracting of soil particles over time. This process causes the soil to move downslope slowly, with a speed typically ranging from a few millimeters to a few centimeters per year.
Is lifting weights mechanical energy?
Yes, lifting weights involves the conversion of chemical energy (from food) into mechanical energy (used to move the weights). The muscles contracting to lift the weights produce mechanical energy.
What type desert erosion involves the lifting and removal of loose material?
Aeolian erosion involves the lifting and removal of loose material in arid deserts. This process is primarily driven by wind, which transports sand grains and other particles to create features like sand dunes.
What is the name of the movement if you were to lift you arm away from your body?

Abrasion and deflation are forms of what type of erosions?
They are forms of wind erosion, where abrasion involves the wearing away of rock surfaces by particles carried in the wind, and deflation refers to the lifting and removal of loose particles by wind action.
What is the proper form for a bicep curl concentric movement?
The proper form for a bicep curl concentric movement involves slowly lifting the weight up towards your shoulders while keeping your elbows close to your body and not swinging the weight.
How does the muscle system work to facilitate movement and support the body's structure?
The muscle system works by contracting and relaxing to move the bones of the body. Muscles are attached to bones by tendons, and when a muscle contracts, it pulls on the bone, causing movement. This movement helps support the body's structure by providing stability and allowing for various activities like walking, running, and lifting objects.
If you were lifting a dumb bell would your muscle be contracting isometrically or isotonically?
Isotonically - The load your are lifting is equal to or less than the force generated by your muscle. Your muscle shortens when it contracts allowing you to lift the dumbbell.
