The force of gravity acting on an object is also that object's weight. When you step on a scale, the scale reads how much gravity is acting on your body. The formula to determine weight is [source: Kurtus]: weight = m x g where m is an object's mass, and g is the acceleration...
A method is used for simulating a gravity acting on an object in space. The method comprises inducing a magnetic moment in the object via generation of an external magnetic field in an environment of the object. A device is used for generating a force acting on an object. The device ...
Sir Isaac Newton developed laws to describe both. Newton's Second Law (_Fnet= ma_) applies to any net force acting on an object, including the force of gravity experienced in the locale of any large body, such as a planet. Newton's Law of Universal Gravitation, an inverse square...
Weight is the downward force caused by gravity acting on an object. If force (F) is mass (m) times acceleration (a), the weight (W) of the fluid displaced is given by its mass (m fluid ) times the acceleration due to gravity (g). The density of the fluid ( fluid ) is ...

Engine using gravity and buoyancy acting on objectsA Gravity-Buoyancy Object Turbine (GBOT) is provided to generate kinetic energy using gravitational force and buoyancy force exist in the nature. The turbine of the invention has a gravity (air) chamber and a buoyancy (liquid) chamber, arranged...
13. Therefore, the present study focuses on the effect of groundwater leakage on the strength of soil mass, on water pressure acting on retaining structure, and on the self- gravity tress of soil mass. 这表明目前在原状土体在开挖过程中水土与支护结构相互作用、水土之间相互作用机理的认识还不够...
2. Gravity has a significant impact on objects, causing them to attract each other and hold together. (重力对物体有重大影响,使它们相互吸引并保持在一起。) 3. Free fall is when an object is in a state of gravity without any external forces acting upon it. (自由落体是物体在没有外部力作用...
In this example, we have a pie chart representing the forces acting on an object. The “Gravity” segment is the largest, indicating that gravity is the dominant force. Visualizing Gravity with Journey Diagrams Another way to visualize the effects of gravity is through journey diagrams. A journe...
The net force acting on an object can be written as F net, obj = W obj + (- F B ) = W obj - F B where the negative sign in front of the buoyant force indicates it acts in an opposite direction to the weight of the object. Substituting for W obj and F B , the equation...
