### NCERT Solutions for Class 11 Physics Chapter 3: Points to Remember

To help guide students in their exam preparations for NCERT 11th Physics Chapter 3 Motion in a Straight Line, we have provided some of the important points to remember below:

• Average speed is the ratio of the total distance to the total time.
• Average Velocity is the ratio of the total displacement to the total time.
• Instantaneous Velocity is the rate of displacement with respect to time
• Average acceleration is the ratio of total change in velocity to the total time taken.
• Instantaneous Acceleration is the rate of change of velocity.
• The slope of the distance-time graph gives speed.
• The slope of the displacement-time graph gives velocity.
• The slope of the velocity-time graph gives acceleration.
• The area under the velocity-time graph gives displacement.
• The area under the speed-time graph gives distance.
• The area under acceleration time gives change in velocity.

## FAQs on NCERT Solutions for Class 11 Physics Chapter 3

Q.1: Why should you solve NCERT solutions for Class 11 Physics chapter 3, Motion In A Straight Line?

Ans: You must practice this chapter as it is an important one and help you score better in your exams and boost you during your practice.

Q.2: What are Instantaneous Speed and Instantaneous Velocity?

Ans: The speed of an object at an instant of time is called instantaneous speed. The instantaneous velocity of a particle is the velocity at any instant or any point of its path.

Q.3: What are the types of motion?

Ans: Motion can be classified as:
a) When a particle moves along a straight line, or a path is said to undergo one-dimensional motion. For example, the motion of a train along a straight line, freely falling body under gravity, etc.
b) A particle moving in a plane is said to undergo a two-dimensional motion—for example, the motion of a shell fired by a gun, carrom board coins, etc.
c) A particle moving in space is said to undergo three-dimensional motion. For example, the motion of a kite in the sky, the motion of an aeroplane, etc.

Q.4: What is the difference between Distance and Displacement?

Ans: Displacement has direction whereas Distance does not have Direction. The magnitude of displacement can be both positive and negative however, Distance is always positive. It never decreases with time.
