Answer the following questions:
The changes in the velocity of a car in specific time intervals are given in the following table.
Explain For all uniformly accelerated motions, the velocity-time graph is a straight line.

For all uniformly accelerated motions, the volcity time graph is a……..

Answer the following questions: The changes in the velocity of a car in specific time intervals are given in the following table. The velocty-time graph in figure shows that, For nonuniformly accelerated motions, the velocity-time graph may have any shape depending on how the acceleration changes with time.Explain.

Answer the following questions : What is escape velocity ?

Answer the following questions: What is velocity ?

Answer the following questions: Define time period.

Answer the following questions: The changes in the velocity of a car in specific time intervals are given in the following table.The velocty-time graph in figure shows that, The velocity changes by equal amounts in equal time intervals. Thus, this is uniformly accelerated motion. How much does the velocity change in every 5 seconds? Find the distance covered by the car in the time interval 10 seconds to 20 seconds.

Answer the following questions: What is accelerated motion?

Answer the following questions : What is the periodic time of AC in India ?

Answer the following questions : Write a short note on escape velocity.

Answer the following questions : Express escape velocity in terms of g and R.
