Force is an interaction that causes an object to change its velocity, direction, or shape, measured in Newtons.

• Force is a vector quantity, meaning it has both magnitude and direction.

• Common examples include gravitational force, frictional force, and tension.

• Newton's second law states that Force = mass × acceleration (F = ma).

• A force can cause an object to start moving, stop moving, or change direction.

Force is a push or pull on an object, while torque is a rotational force around an axis.

• Force is a vector quantity, measured in newtons (N), acting in a straight line.

• Torque is also a vector quantity, measured in newton-meters (Nm), and causes rotation.

• Example of force: Pushing a car to move it forward.

• Example of torque: Using a wrench to tighten a bolt, where the force applied creates rotation.

Laser beam machining is a non-traditional manufacturing process using focused laser beams for cutting, engraving, and material removal.

• Uses high-intensity laser beams to melt or vaporize materials.

• Commonly used for cutting metals, plastics, and ceramics.

• Offers high precision and minimal thermal distortion.

• Applications include aerospace, automotive, and electronics industries.

• Examples: Laser cutting of sheet metal, engr

An air compressor is a device that converts power into potential energy stored in pressurized air.

• Air compressors work by drawing in air and compressing it to increase pressure.

• They are commonly used in various applications, such as powering pneumatic tools.

• Examples include portable air compressors for inflating tires and industrial compressors for manufacturing.

• Compressors can be categorized into positive displacement
