When an object is immersed within a fluid, for example air or water, the volume of the fluid displaced will contribute to an upward force. The amount of fluid displaced will cause a force of equal …

Objects that float have something known as buoyancy which is an upward force that exists when the specific object has less density than the surrounding medium. The mass of the object is important, …

When pressure is exerted it will act and then resolve to equilibrium quickly. If you squeeze toothpaste it will come out the other end and then stop moving. Pressure coming from a tire jack can have …

Fluids behave and interact with forces differently than solids might. A fluid cannot sustain a shear force (a force parallel to the surface). When you’re talking about a fluid it is also more useful …

The Earth travels around the sun in an elliptical pattern, but it is still fairly close to a circular orbit. The seasons on Earth are determined by the angle of sunlight that hits the planet …

In space there is potential energy that is gravitational, similar in some ways to the potential energy associated with height on earth, but also different. Two objects must be present and the …
