Work is defined as the transfer of energy from one object to another. It occurs when a force is applied to an object, causing it to move in the direction of the force.
Work and kinetic energy are closely related. The work done on an object is equal to the change in its kinetic energy. This means that when work is done on an object, its kinetic energy increases and vice versa.
The formula for calculating work is W = F x d, where W represents work, F represents the force applied, and d represents the distance the object moves in the direction of the force.
Kinetic energy is calculated using the formula KE = 1/2 x m x v^2, where KE represents kinetic energy, m represents the mass of the object, and v represents the velocity of the object.
Yes, work can be negative. This occurs when the force applied to an object is in the opposite direction of the object's motion. This means that the work done on the object results in a decrease in its kinetic energy.
