Uniform motion: When an object covers equal distances in equal intervals of time, it is said to be in uniform motion.
Non-uniform motion: Motions where objects cover unequal distances in equal intervals of time. Speed: The distance travelled by an object in unit time is referred to as speed. Average speed: For non-uniform motion, the average speed of an object is obtained by dividing the total distance travelled by an object by the total time taken.
Velocity: Velocity is the speed of an object moving indefinite direction. Acceleration: Change in the velocity of an object per unit time. Graphical representation of motions i Distance-time graph For a distance-time graph, time is taken on x-axis and distance is taken on the y-axis. RD Sharma Class 12 Solutions. Watch Youtube Videos.
