Question

speed and velocity - 7.7a, 7.7b
select two correct answers. both trains have the same-
speed
distance
time
velocity
direction

Explanation:

Step1: Understand the concepts

Speed is a scalar quantity (only magnitude). Velocity is a vector quantity (magnitude + direction). Distance is how much ground an object has covered. Time is the duration. Direction is the path orientation.

Step2: Analyze the trains

Assuming they are moving in the same line (from the track setup in the image - same path direction). If they are moving, and the problem is about basic motion properties. If we assume they start from the same point (as per the track alignment in the image) and move along the same track (same direction). If we consider a time - interval (say we are comparing their motion over the same time period). For speed: if they cover equal distance in equal time (from the track - same length of train movement assumed in the image's track setup, same time frame as per the problem's context of comparing their properties). For direction: same track implies same direction.

Answer:

speed, direction
