work
The work done by applying a force through a distance is known as mechanical work. It is calculated by multiplying the magnitude of the force by the distance it is applied over, and it results in the transfer of energy to the object being moved.
The work done is directly proportional to the distance through which the force is applied. This is known as the Work-Energy Principle, where work is equal to force multiplied by distance. So, increasing the distance over which a force is applied will result in more work being done.
The process described, changing the energy of a system by applying a force over a distance, is known as work. Work is calculated as the product of the force applied and the distance over which the force is exerted. This work can result in the transfer of energy to or from the system being acted upon.
When a simple machine helps reduce force, the distance the object moves increases. This is known as a trade-off between force and distance in mechanical systems. By applying less force over a longer distance, simple machines make it easier to perform work.
The child pushing the toy car is applying a force known as a contact force, specifically a pushing force. This force is directly applied through physical contact between the child and the toy car.
We do work when we apply a force through a distance.

The product of the force applied and the distance moved in the direction of the force is known as work. Work is calculated as the force multiplied by the distance, and it represents the amount of energy transferred to an object when force is applied to move it over a certain distance.

The quantity that measures how much a machine multiplies force or distance is known as mechanical advantage. It is calculated as the ratio of the output force to the input force, or the ratio of the input distance to the output distance in a machine.
Gravitational force depends on the masses involved, and on the distance. There is no known way to "block" the gravitational force.
When you lift a book, you are applying a force against gravity to increase its height. Work is done when a force is applied to move an object over a distance in the direction of the force, so lifting the book requires work to be done against gravity.
The size of the turning effect of a force, or torque, depends on the magnitude of the force and the distance from the pivot point at which the force is applied. The longer the distance from the pivot point, known as the moment arm, the greater the turning effect produced by the force.
