4. What do you infer if?
1 Distance -time graph is straight line
2 Velocity –time graph is curved
3 Displacement -time is zig zag
Answers
Explanation:
If Displacement time graph is straight line then velocity is constant !
Velocity time graph is curved accerleration is keep changing.
Displacment time graph is zigzag then velocity is changing fastly
Answer:
Distance -time graph is straight line : Speed is constant
Velocity –time graph is curved: Acceleration is not uniform
Displacement – time is zigzag -Non uniform velocity
Explanation:
Distance -time graph is straight line : Speed is constant
If the distance and the time graph is straight line then the speed of the object is constant
Velocity –time graph is curved: Acceleration is not uniform
If the velocity and time graph is curved then the acceleration of an object is not uniform
Displacement – time is zigzag -Non uniform velocity
If the displacement and time is zigzag then the velocity of an object is non uniform.
Speed is constant:
We refer to an object as travelling at a constant speed when its speed is constant and neither rises nor falls.
Acceleration is not uniform
When a feather hits the ground during a strong storm, its velocity fluctuates, sometimes decreasing and other times increasing unevenly over the course of equal time intervals. As a result, it can be used as an illustration of non-uniformly accelerated motion.
Non uniform velocity
When something moves in a specific direction over uneven distances at equal periods of time. It is considered to be travelling with a non-uniform or variable velocity if the direction of motion changes.
