Work is the transfer of energy that occurs when a force is applied to an object and causes it to move a certain distance.
The work done on a sled is directly related to its change in kinetic energy. When a force is applied to the sled, it gains kinetic energy and the work done on the sled is equal to the change in its kinetic energy.
The work done on a sled and its kinetic energy are affected by the force applied to the sled, the distance the sled moves, and the mass of the sled. The direction of the force also plays a role in determining the work done and the change in kinetic energy.
The work done on a sled can be calculated by multiplying the force applied to the sled by the distance the sled moves in the direction of the force. This can be represented by the equation W = Fd, where W is work, F is force, and d is distance.
Work is a scalar quantity, meaning it only has magnitude and no direction. This is because it is the product of two scalar quantities (force and distance) and does not depend on direction for its calculation.
