How to determine according to the graph of the dependence of the projection of speed on time: 1) module of movement; 2) the path covered by the point?
1) the module of movement according to the graph of speed versus time can be determined by calculating the area under the graph.
2) the path covered by the point, according to the graph of the dependence of speed on time, can be determined by summing up the areas under the graph.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
