1.Near the surface of the Earth, an object in free fall in a vacuum will accelerate at approximately 9.8 m/s2, independient of its mass. With air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (195 km/h or 122 mph) for a human skydiver.
3.An object with constant velocity travels the same distance in the same direction in each time interval. The motion diagram in Figure 2.9 shows equally spaced images along a straight line.
4.Negative acceleration always indicates that the acceleration is in the direction opposite to that of the motion of the body. Hence, negative acceleration (or retardation) always means that the body is slowing down.
