The correct answer is Important Points
**Motion**is the change in position of an object with respect to time and its surroundings.- The motion of an object can be
**uniform or non-uniform**based on its velocity(whether is constant or changing). **Distance**covered by a body is the actual length of the path travelled the body.- The distance travelled by a body in unit time is called
**speed.**
Key Points
- When the distance travelled by an object is directly proportional to the time, it is said to travel with
**constant speed.** - An object is said to be in uniform speeds when the object travels
**equal distances in equal interval of time.** - Uniform and non-uniform motions of objects can be shown through graphs.
- The speed of an object can be determined from the
**distance-time graph.** - The
**velocity**of an object is the displacement per unit time. - The acceleration of a moving object is the rate of change in velocity.
