... We’ve been solving physical problems treating objects as sizeless points with masses, but in realistic situations objects have shapes with masses distributed throughout the body. Center of mass of a system is the average position of the system’s mass and represents the motion of the system as if all ...

... The last stage of a rocket is traveling at a speed of 7600 m/s. This last stage is made up of two parts that are clamped together, namely, a rocket case with a mass of 290.0 kg and a payload capsule with a mass of 150.0 kg. When the clamp is released, a compressed spring causes the two parts to sepa ...

The physics of negative mass
... there is no evidence that any anti-particles have negative mass. In fact, the idea that antiparticles, such as the positron, are regular particles, such as the electron, going backwards in time is probably no more than a convenient fantasy, since both positrons and electrons have positive mass. This ...
