(I) Lengths and time intervals depend on the factor

according to the theory of relativity (Eqs. and . Evaluate this factor for speeds of: (a) (typical speed of a satellite); b) (c) ;

NEWTON’S SECOND LAW ● an object’s change in motion (acceleration) is directly proportional to applied force ● an object’s change in motion (acceleration) is inversely proportional to the object’s mass ● mass is just a measure of inertia, an object’s stubbornness or resistance to change in its motion ● a = f/m ● mass is a property of the object ● force is an outside influence on the object ● weight is an example or special case of force ● this is why everything falls alike = all objects have the same law of weight/mass
