Explanation:
it has no retardation means negative accelertion it has positive eccelation
Question :
Show the velocity time graph to object in uniformly acceleration motion show that slope of velocity time graph give the acceleration of object.
The object starts from point D in the graph with velocity u. It's velocity keeps increasing and after time t, it reaches the point B on the graph.
Given:
- The initial velocity of the object = u = OD.
- The final velocity of the object = v = OC
- Time = t = OE
Solution :
CD = at .... ( i ) ( OC - OD = CD )
We need to draw parallel to Y axis passing through B. This will cross the X axis in E. Draw a line parallel to X-axis passing through D. This will cross the line BE at A.
From the graph.... BE = AB + AE
V = CD + OD...... ( AB = CD and AE = OD )
V = at + u.......... ( from (i) )
therefore, V = u + at
This is the first equation of motion.
Remember !
The velocity of an accelerated object changes with time. Change in the velocity can be due to a change in direction or magnitude of the velocity or both.
