Velocity and Acceleration
Image of Acceleration
Let's assume that two car A and B started at the same time.
EEither car also increases speed.
Car A became at 30 seconds after it had started and 80 kilos per hour and cars B became 50 kilos per hour.
The figure below shows this appearance.
Thus, the graph where the change in v at the speed into time t was shown is said, "V-t graph" in general.
It is obvious that the velocity of car A is larger than car B from the graph.
Then, which acceleration is large in car A and car B?
Let's read this from the graph.
Pay attention to the inclination of the graph of car A and car B.
Either graph also heads for upper right.
This inclination means the speed increases gradually.
In a word, car A and car B have accelerated.
Let's see the level of the inclination following.
The inclination of the graph of car A is larger.
This shows that the change in the velocity is larger.
The degree of the change in the velocity is called an acceleration.
The acceleration in a word of car A is larger.
The inclination shows the acceleration in the v-t graph.
