. The Diaoyu Islands is China's territory since ancient times, and straight line
distance between Diaoyu Island and Wenzhou is 356km. One day morning, China Marine Surveillance ship to safeguard China’s sovereignty over Diaoyu
Island, departed from Wenzhou at 8:00am to Diaoyu Islands, sailing 480km, which lasted 8hours and 20mins to arrive Diaoyu Island. Which of the following statement is correct. ( )
8:00 means the time length during
8hours and 20mins means the time instant
the displacement of the ship is 480km, distance is 356km
the distance and displacement are the same size.
which of the following statement is correct( )
the start price of Taxi is 10.00RMB (less than 2km), the “2km” means displacement
when we analyze movement of a man when he is walking along a straight road, the man can be regarded as a particle
distance and displacement can be the same direction.
shown in the given diagram, projected a particle vertically upward from 3m high above the ground, it moves up for 5m to the height position, then falls back to ground. What is the displacement and distance if set ground as origin.
3m, 5m
3m, 13m
-3m, 5m
-3m, 13m
GPS on the car shows in a given diagram, which of the statement is not correct ( )
when we use GPS, car can be seen as a particle.
the 11.6km in “备选方案二” means displacement
22mins in “时间最短方案”means time length.
