Yes, require to spend energy
For an object to require potential energy a force must be acting on it in a certain direction. Even though the object doesnt move doesnt mean it has potential energy. The most common force of otential energy is Gravity. When an object is lifted off the ground gravity becomes stronger. For a formula of proof then use E=FxD (Energy=Force applied x Distance travelled). If a ball has been lifted by 10 Meters with a force of 500 Newtons then it has a Potential Energy of 5000 Newton Meters,
no it doesnt
"Kinetic energy" is energy related to movement. If there is no movement, there is no kinetic energy.
A pulley on its own does not require any energy, as it's not doing anything.
no there must at least be an initial input to get it started.
no it does not require energy.
endothermic reactions require energy
All of your cells require energy. Without energy you wouldn't be alive.
thinking, dreaming require energy
All living organisms (not dead) require energy
Endocytosis is the bulk transport of materials into a cell, using energy in the form of ATP. It is an active process, and the energy is used to move the membranes around the materials to form the vesicles that are needed, and to move the vesicles into the cell.
No, it does not require energy use from the cell.
All living organisms (not dead) require energy
Yes, require to spend energy
no it doesnt you dont have to count
