thermel energy
Electric energy is typically used to power the motors that generate force to lift an object, such as in elevators or cranes. This electric energy is converted into mechanical energy to lift the object against the force of gravity.
The tension rope pulley can be used to efficiently lift heavy objects by distributing the weight of the object across multiple pulleys, reducing the amount of force needed to lift it. This allows for a mechanical advantage, making it easier to lift heavy objects with less effort.
Scissors use mechanical energy when they are used to cut objects. The energy is transferred from the user's hand to the blades of the scissors, enabling them to perform cutting action.
A lever is used to lift heavy objects because it magnifies the input force applied to it. By using a lever, a person can apply a smaller force over a longer distance to lift a heavier load over a shorter distance. This principle allows for the efficient lifting of heavy objects with less effort.
Kinetic energy is the movement of objects that can be used to do work. When an object is in motion, it possesses kinetic energy which can be transferred to other objects to perform tasks or create changes in their positions. The amount of kinetic energy an object has is dependent on its mass and velocity.

because we can't lift it with our hand
levers are used to lift up objects

Yes, a pulley is a simple machine that is commonly used to lift heavy objects by reducing the amount of force required to lift them. It works by changing the direction of the force applied and distributing it evenly among multiple ropes or cables, making it easier to lift heavy loads.
The pulley was discovered to lift objects that would otherwise be too heavy to lift. Much in the way a crane is used to lift cargo onto ships.
kinetic energy
No energy= no movement
A pulley can be used to lift heavy objects, lower objects, or to change the direction of a force. It is commonly used in various applications such as construction, manufacturing, and transportation to make tasks easier and more efficient.
