AC changes direction periodically while DC flows in one direction continuously.

• AC changes direction periodically, while DC flows in one direction continuously

• AC is commonly used in household appliances and power distribution systems

• DC is commonly used in batteries and electronic devices

• AC voltage can be easily converted using transformers, while DC voltage requires more complex conversion methods

Grounding is the process of connecting an electrical circuit or device to the earth or to a reference point that is at the same potential as the earth.

• Grounding helps to prevent electric shock and protect equipment from damage.

• It provides a path for excess electrical current to flow safely to the ground.

• Grounding also helps to reduce electromagnetic interference and improve the performance of electrical systems.

Newton's 2nd law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

• F = ma (force equals mass times acceleration)

• Acceleration is in the same direction as the net force

• The greater the force applied to an object, the greater its acceleration

• The greater the mass of an object, the smaller its acceleration for a given force
