Energy-free movement of materials through a cell membrane is called passive transport. This process includes diffusion, osmosis, and facilitated diffusion, where molecules move from an area of high concentration to an area of low concentration without the input of energy.
A system that allows energy but not matter to pass through is a selective permeable membrane. This membrane allows the transfer of energy in the form of heat or light, but prevents the passage of physical particles or substances. This process is commonly seen in technologies such as solar panels or insulating materials.
Materials with high thermal resistance, such as insulation or materials with low thermal conductivity, can slow the movement of thermal energy by reducing the rate of heat transfer through them. Additionally, the presence of air pockets or vacuum layers can also impede the transfer of thermal energy by limiting the movement of molecules.
A saw can exhibit kinetic energy when it is in motion, such as when cutting through materials. The movement of the saw blade results in kinetic energy being transferred to the object being cut.
The movement of water molecules without the use of energy is called passive transport. This is a process where water molecules move across a cell membrane from an area of higher concentration to an area of lower concentration, known as osmosis. In this way, water can move freely through a cell membrane without the need for energy input.
The process of generating electricity through the movement of light charge particles is called photovoltaic effect. This involves converting light energy into electrical energy using materials like silicon in solar panels.
it is the movement of materials through cell membrane using energy

Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
It's called passive transport for a cell's membrane. (I checked with my science teacher)
This type of movement is called simple diffusion.
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
active transport
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
