EQUATIONS OF MOTION
SCERT CLASS IX PHYSICS PART 1 CHAPTER 2
Term | Definition |
---|---|
EQUATION SHOWING VELOCITY-TIME RELATION | v = u +at |
EQUATION SHOWING POSITION-TIME RELATION | s = ut +1/2 at^2 |
EQUATION SHOWING POSITION-VELOCITY RELATION | v^2 = u^2 + 2as |
WHAT IS A GRAPH? | Two dimensional diagram. It can be depicted connecting two values. A graph will have two axes. The horizontal axis is the X-axis and the vertical Y-axis. |
POSITION-TIME GRAPH OF A BODY MOVING WITH UNIFORM SPEED WILL BE | Straight line |
POSITION-TIME GRAPH OF A BODY MOVING WITH NON-UNIFORM SPEED WILL BE | Not a Straight line |
IN VELOCITY-TIME GRAPH | Displacement of a body within a definite interval of time is equal to the area of the portion. |
