... 2. What is the velocity of an object that has a momentum of -30 kg m/s and a mass of 3.0 kilograms? If p = mv, then v = p/m = (-30 kg m/s)/(3.0 kg) = -10 m/s 3. Two objects have equal momentum but one has four times the mass of the other. What is the relationship ...

... internal forces, and the internal forces can not exert a net force on the system, only an external force can do that. Whenever a system exists without external forces—a system that we call a closed system—the net force on the system is always zero and the law of conservation of momentum always holds ...

... in its volume, the normal force per unit area is called bulk stress or volume stress. 13. Bulk stress is equal to pressure or change in pressure also called hydraulic pressure. 14. Shearing stress or Tangential stress : When a tangential force is applied on a body such that there is a change in shap ...

... 3) If you stand on a pair of bathroom scales, explain how the readings change as you shift your weight gradually from side to side. What rule governs the readings on the scales? Answer: The equilibrium rule guides the scale readings. That is, the total of the readings adds to equal your weight. The ...
