Constant Force: Work is calculated as the dot product of force and displacement. The formula is W = Fs cos theta.Variable Force: When force changes with position, work is the integral of the force-displacement function. This is graphically represented as the area under a Force-Position graph.Sign Convention: Work is positive if the angle is acute, negative if obtuse (like friction), and zero if the force is perpendicular to motion (like centripetal force). Energy and the Work-Energy Theorem

Power measures how fast work is being done. It is a scalar quantity measured in Watts. work energy power neet notes pdf download

Work is done when a force acts upon an object to cause a displacement. In physics, work is a scalar quantity, but its value can be positive, negative, or zero depending on the angle between the force and displacement vectors. Constant Force: Work is calculated as the dot

Collisions involve the interaction of bodies over a short time interval. Energy and the Work-Energy Theorem Power measures how

Energy is the capacity to do work. For NEET, focus heavily on Mechanical Energy, which is the sum of Kinetic and Potential energy.
