In summary, the force that determines who wins in a tug-of-war is the force that is exerted by the person against the car. The greater the force, the more likely the person is to be injured. Oct 22, 2007 #1 St@rbury 29 0 Physics Quiz...very Urgent! 1.As a rocket rises ...

To get the 'just enough' condition- so you start to get motion, you just have to replace the Equation with an Inequality - giving the same numerical answer. Sep 8, 2014 #136 CWatters Science Advisor Homework Helper Gold Member 10,544 2,323 bobie said: Specific question: the ...
Perhaps the most fundamental aspect of physics is the relationship between an applied force and the motion of an object. Because forces and motion permeate so many levels of physics, they allow a plethora of hands-on activities for students. Students just introduced to the material can benefit f...
SummaryA number of possible mechanisms have recently been proposed for driving the motions of the lithospheric plates, such as pushing from mid-ocean ridges, pulling by downgoing slabs, suction toward trenches, and coupling of the plates to flow in the mantle. We advance a new observational meth...
External forces act from outside of the system, and the work that they do on a system changes the mechanical energy of the system. For example, the friction force will always act to oppose motion so it is an external force.What is External Force? A force is something that acts on an ...
Summary: The objective of this study was to measure the resultant force in the human bone–patellar tendon–bone graft after reconstruction of the anterior cruciate ligament under various conditions in vitro. Seven fresh-frozen cadaver lower extremities were used. Force measurement was made with a ...
Or in general, it is any action that can change the motion of an object. If an object has no forces on it, and then you apply a force by, for example, pushing it, the object will accelerate. An acceleration is a change in the velocity of an object over time. So if the forces ...

A schematic of the three stages of cell movement, based on [1,12]: after determining its direction of motion, the cell extends a protusion in this direction by actin polymerization at the leading edge. It then adheres its leading edge to the surface on which it is moving and de-adhere...
