​

Answer 1

According to the given displacement time graph,

Question: What is the displacement taken after every second?

Answer: Displacement taken after every second is 3 m.

Question: Is velocity uniform? Give a reason? Why?

Answer: Yes, the velocity is uniform in the given displacement time graph as the slope of the graph is straight.

Question: If displacement time graph for a particle is a straight line parallel to the time axis, what will be the velocity of the particle?

Answer: If displacement time graph for a particle is a straight line parallel to the time axis then the velocity of the particle must be zero as it is not moving from a distance to another in the time. $\:$

Additional information:

→ In a velocity-time graph, the slope of graph tell us about the acceleration. Yes, the acceleration can be negative or zero too even we know that acceleration can be positive too. If the slope is high then the acceleration is positive, if the slope is low then the acceleration is negative and if the slope is parallel to time axis then there is no acceleration taking place as if the velocity is constant then ofcourse the acceleration is zero.

↪️ A v-t graph parallel to x axis, represents, uniform motion of a body that have a constant speed

↪️ The slope of D-T graph gives the _____ of the object in motion.

• The slope of Distance Time or Displacement Time graph give the speed of the object in motion.

↪️ Distance or displacement are same in the matter of graphs in motion

↪️ Speed and velocity are same in the matter of graphs in motion

↪️ The slope of V-T graph gives the _____ of the object in motion.

• The slope of Velocity Time graph give the acceleration of the object in motion.

↪️ The area under curve of V-T graph gives the _____ of the object in motion.

• The area under curve of Velocity Time graph gives the distance/displacement of the object in motion.
