Is static friction the same as the centripetal force? Why is centripetal force the sum of all forces? How is centripetal force generated? In the centripetal force equation, what is the mass equal to? Does an increase in centripetal force increase acceleration? What forces provide centripetal forc...
Is acceleration an applied force? Why does the normal force not cause any acceleration? Does static friction depend on the normal force? Define normal force Does the normal force always oppose the force of friction? Force equals mass times ...
Newton's first law of motion(运动) says 27 no acceleration(加速)can happen without an unbalanced force. Here, acceleration means“change in motion" and force means “ a push 28 a pull". Another way to say Newton's first law is this: Objects which are at rest don't move unless an ...
manner using technical terminology where appropriate) Man pulls (backward) on the support Due to N3 the support exerts a (opposite) force on the man This force is a resultant/unbalanced/net force on man Due to N1/N2 the man will accelerate With the same acceleration/speed/velocity as the ...
A model of inertia is given where inertia is a result of unbalanced radiation absorption during acceleration. The unbalance is ascribed to a combination of the Doppler effect and the quantum nature of photons. With a systems model for the cause of remote forces, various experiments to achieve ...

Homework Statement Consider an airplane of wing area 29 m^2 (both wings combined) flying through air of density0.549 kg/m^3 . From the plane’s point of...
A force can be a push or a pull. A force acting on a body tend to produce a change in velocity or acceleration of the body.
In a gasoline engine, the motion of the piston is simple harmonic. The piston has a mass of 2 kg and stroke (twice the amplitude) of 10 cm. find maximum acceleration and the maximum unbalanced force on the piston, if it is making 50 complete vibrations each minute. ...
