FAQs

Question: What is uniform motion?
Answer: Uniform motion refers to the motion of an object moving at a constant speed in a straight line.

Question: How do I calculate relative speed?
Answer: Relative speed is calculated by adding or subtracting the speeds of two objects depending on their direction of motion.
