Final answer:
The radial velocity of an object with respect to a given point is the rate of change of the distance between the object and the point.
Step-by-step explanation:
The statement True. The radial velocity of an object with respect to a given point is indeed the rate of change of the distance between the object and the point. This means that if the object is moving closer to the point, its radial velocity will be positive, and if it is moving away from the point, its radial velocity will be negative. For example, if a car is driving towards a traffic light, the radial velocity of the car with respect to the traffic light will be positive as the distance between them is decreasing.
