Answers
The relation between the distance and time:
The relation between the distance and time when a body is moving in two different condition is either proportional or not proportional.
When the body moves with a uniform velocity i.e., it does not change its speed or direction over the travel, the relation of distance and time is proportional, that is distance travelled remains proportional with the time.
When the body moves with variable velocity i.e., it changes speed or direction over the travel, the relation becomes non proportional that is distance travelled is not proportional with the time.
Answer:
1.) Velocity of a particle is equal to the slope of its displacement- time graph
2.) Acceleration of a particle is equal to the slope of velocity time graph
3.) Displacement of a particles in a given time interval is equal to the total area under the velocity time graph in the given time interval
4.) velocity of. a particles in a given time interval is equal to the total area under the accelerattion time graph
