Final answer:
Acceleration is the rate of change of an object's velocity over time. When an object is accelerating towards a point, it means that its velocity is changing and it is getting closer and closer to that point.
Step-by-step explanation:
Acceleration is the rate of change of velocity over time and is a vector quantity, meaning it has both magnitude and direction. When an object is accelerating towards a point, it means that its velocity is changing and the rate of change is such that it is getting closer and closer to that point.
For example, if a car is accelerating towards a stop sign, its velocity is decreasing over time and it is getting closer to the stop sign. Similarly, if a ball is thrown upwards and its velocity is decreasing due to gravity, it is getting closer to its highest point.
It is important to note that acceleration can be positive or negative depending on the direction of the change in velocity. A positive acceleration indicates an increase in speed or a change in direction towards the point, while a negative acceleration indicates a decrease in speed or a change in direction away from the point.
