Explaining The Universe on Instagram: "Centripetal force is the inward-directed force that keeps an object moving along a curved or circular path instead of flying off in a straight line. Whenever something turns—like a car rounding a corner, a ball being swung on a string, or a planet orbiting the Sun—it requires a constant pull toward the center of the circle to maintain that motion. This inward force can come from different sources, such as friction, tension, or gravity, depending on the situ

Science on Instagram: "Density is a characteristic physical property of a liquid, defined as its mass per unit volume (  ρ=mass/volumerho equals mass / volume 𝜌=mass/volume ). It determines how closely the molecules are packed together and dictates whether a liquid will float or sink when layered with another substance. Key Characteristics and Factors The density of liquids is relatively constant compared to gases, as liquids are nearly incompressible under normal pressures. Molecular Makeup:
