Gravity problems are presented along with detailed solutions. Problem 1: An object is dropped, with no initial velocity, above the surface of planet Big Alpha and falls 13.5 meters in 3 seconds. The radius of planet Big Alpha is 5.82×10 6 meters. a) What is the acceleration of the falling object? b) What is the mass of planet Big Alpha?
Apply Newton’s laws of motion to solve problems involving a variety of forces. Use trigonometric identities to resolve weight into components. Normal Force. Weight (also called force of gravity) is a pervasive force that acts at all times and must be counteracted to keep an object from falling.
Cohesive forces between molecules cause the surface of a liquid to contract to the smallest possible surface area. This general effect is called surface tension. Molecules on the surface are pulled inward by cohesive forces, reducing the surface area.

12 lut 2020 · Surface tension is a phenomenon in which the surface of a liquid, where the liquid is in contact with a gas, acts as a thin elastic sheet. This term is typically used only when the liquid surface is in contact with gas (such as the air).
Examples of Surface Tension. Surface and interfacial tensions can have a strong influence on several essential phenomena in everyday life. As a result, many chemicals and techniques have been developed for modifying the surface and interfacial tensions. 1. A Drop of Liquid
