Free fall: Free fall is when an object accelerates due to a gravitational field, with air resistance and other forces not included.An object undergoing free fall will accelerate at g, regardless of its mass. This is because: is the force acting, from . therefore, so Acceleration is directly proportional to force and inversely proportional to weight.

Turning - A single-point turning tool moves axially, along the side of the workpiece, removing material to form different features, including steps, tapers, chamfers, and contours. These features are typically machined at a small radial depth of cut and multiple passes are made until the end diameter is reached.
Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO 2) or steel balls), acting as grinding media and rotating shell to create centrifugal force.In this process, graphite (precursor) was breakdown by randomly striking with grinding media in the rotating shell to create shear …

• Static indentation tests: A ball, cone, or pyramid is forced into the sur-face of the metal being tested. The relationship of load to the area or depth of indentation is the measure of hardness, such as in Brinell, Knoop, Rockwell, and Vickers hardness tests. • Rebound tests: An object of standard mass and dimensions is bounced
