Final answer:
The term 'accompanying driver' does not apply to the context of external forces in physics. True, external forces act on an object from outside the system. False, objects in space move according to Newton's laws without external forces. Newton's First Law explains the constant velocity of a car on a straight road.
Step-by-step explanation:
The statement 'An accompanying driver must stay outside the vehicle at all times' when referring to the context of external forces is not relevant as it seems to mix driving rules with concepts of physics. However, to address the items presented:
- 39. True or False - An external force is defined as a force generated outside the system of interest that acts on an object inside the system. The answer is True.
- 46. True or False - An external force is required to set a stationary object in motion in outer space away from all gravitational influences and atmospheric friction. The answer is False. In outer space, the lack of opposing forces means that an object at rest will remain at rest, and an object in motion will continue in motion at a constant velocity (newton's first law).
- 33. If a car is moving on a straight road at a constant speed in a single direction, it means that the net force acting on the car is zero according to Newton's First Law of Motion.
- 3. True or False - A planet-satellite system must be isolated from other massive objects to follow Kepler's laws of planetary motion. This statement is too strict; while significant perturbations can affect orbits, many planet-satellite systems are not completely isolated yet still approximately follow Kepler's laws.
