One airplane travels due north at 300 km/h while another travels due south at 300 km/h. Select the false statement.
The airplanes have the same speed The airplanes have the same velocity
The airplanes have the same speed -true
The airplanes have the same velocity-false
Same speed
the velocity is the same
To determine which statement is false, we need to understand the difference between speed and velocity.
Speed is a scalar quantity that refers to how fast an object is moving, irrespective of its direction. It is given by the formula: speed = distance / time. In this case, both airplanes are traveling at a speed of 300 km/h.
Velocity, on the other hand, is a vector quantity that includes both speed and direction. It is given by the formula: velocity = displacement / time. Displacement is the change in position of an object, which takes into account its starting and ending points.
In this scenario, since one airplane is traveling north and the other is traveling south, they have different directions. Therefore, the false statement is "The airplanes have the same velocity."
