Answers
Answer:
1) the action or process of moving or being moved is called motion.
the rate at which someone or something moves or operates or is able to move or operate is called speed.
The time period is the time taken by a complete cycle of the wave to pass a point, Frequency is the number of complete cycle of waves passing a point in unit time is called time period.
movement back and forth in a regular rhythm is called oscillation.
2) speed=distance/time
d=√(x^2 - x^1)^2+(y^2-y^1)^2
time=distance/speed
3) The basic difference between uniform and non-uniform motion is that: In uniform motion, a body moves with a constant speed such as Motion of earth around the sun. While in non-uniform motion a body moves with a variable speed such as Horse running in the race.
