Atwood Machine
A system consisting of two masses connected by a string over a pulley, used to study motion and forces. Energy Conservation
A principle stating that the total energy in an isolated system remains constant over time. Kinetic Energy
The energy possessed by an object due to its motion, calculated as 1/2 mass times velocity squared. Potential Energy
The energy stored in an object due to its position in a force field, such as gravitational potential energy. Gravitational Potential
Energy an object possesses due to its position in a gravitational field, often relative to a reference point. Non-Conservative Forces
Forces that cause energy dissipation from a system, such as friction, not present in this problem. Pulley
A wheel on an axle designed to support movement and change of direction of a taut cable or belt. Initial Velocity
The velocity of an object at the start of a time interval, zero in this problem as the system starts from rest. Final Speed
The speed of an object at the end of a time interval, calculated as 2.56 m/s for both blocks in this problem. Height
The vertical distance of an object from a reference point, 3 meters for Block B initially. Mass
A measure of the amount of matter in an object, 5 kg for Block B and 4 kg for Block A in this problem. Acceleration
The rate of change of velocity of an object, same for both blocks due to their connection. String
A thin piece of material connecting two objects, transmitting force and motion in the system. System
A set of interacting components considered in a problem, such as the blocks and pulley in this example. Equation
A mathematical statement that asserts the equality of two expressions, used to solve for final speed.
