What is straight line motion class 11?
A particle moving along a straight-line or a path is said to undergo one dimensional motion. For example, motion of a train along a straight line, freely falling body under gravity etc. (ii) Two dimensional motion. A particle moving in a plane is said to undergo two dimensional motion.
What is a straight line in motion?
What is Motion in a Straight Line? If an object changes its position with respect to its surroundings with time, then it is called in motion. It is a change in the position of an object over time. Motion in a straight line is nothing but linear motion.
What are the topics in motion in straight line Class 11?
The topics covered in these notes are Speed, Uniform Speed, Variable Speed, Average Speed, Instantaneous Speed, Velocity, Uniform Velocity, Variable Velocity, Average Velocity, Uniform Motion in a straight line and Relative Velocity.
What is the formula of motion in a straight line?
Key Equations
Displacement | Δx=xf−xi |
---|---|
Instantaneous speed | Instantaneousspeed=|v(t)| |
Average acceleration | ˉa=ΔvΔt=vf−x0tf−t0 |
Instantaneous acceleration | a(t)=dv(t)dt |
Position from average velocity | x=x0+ˉvt |
What is meant by motion in a straight line write an example of such a motion class 9?
The motion which is in the same path or direction without changing it path or directions is called straight line motion. EXAMPLE = 1)the car moving in the same path.
Is motion in straight line important for NEET?
Important notes of Physics for NEET, JEE for Motion in a Straight line are useful for all aspirants preparing for entrance exams including JEE, NEET. Important notes are also helpful for revision when you have less time and have to study many topics.
What is meant by motion in straight line give some example?
Examples of motion in a straight line or rectilinear motion are: (i) A bus moving on a straight road, (ii) A train moving on a straight track, (iii) A runner running along a straight track, (iv) A ball moving along a straight path, and.
What are the examples of motion in straight line?
If the motion of the object is only in one direction, it is said to be the motion in a straight line. For example, motion of a car on a straight road, motion of a train on straight rails, motion of a freely falling body, motion of a lift, and motion of an athlete running on a straight track, etc.
What are types of motion?
According to the nature of the movement, motion is classified into three types as follows:
- Linear Motion.
- Rotary Motion.
- Oscillatory Motion.
Is motion in a plane important for NEET?
Important notes of Physics for NEET, JEE for Motion in a Plane are useful for all aspirants preparing for entrance exams including JEE, NEET. Important notes are also helpful for revision when you have less time and have to study many topics.
Is there NEET in 2021?

Which of the following is an example of motion in a straight line?
The correct answer is A ball thrown straight up and falling back straight down. Linear motion involves an object moving from one point to another in a straight line.
What is Class 11 physics all about?
This chapter of NCERT Class 11 Physics will be covering simple but essential topics such as comparing the objects as a point object. We will be plotting graphs and determine values according to them.
Which relations are correct in NCERT solutions for Class 11 Physics?
Only the relations (c), (d) and (f) are correct. For students of Class 11, the topics that come under the NCERT Solutions for Class 11 Physics Chapter 3 Motion in a Straight Line are important as they lay out the foundation for the topics to follow in the future.
When is an object said to be in motion?
“An object is said to be in motion if its position changes with time”. The concept of motion is a re’ live one and a body that may be in motion relative to one reference system, may be at rest relative to another.
Is it correct to say that the particle moves in straight line?
It is not correct to say that the particle moves in a straight line for t < 0 (i.e., -ve) and on a parabolic path for t > 0 (i.e., + ve) because the x-t graph does not represent the path of the particle. A suitable physical context for the graph can be the particle is dropped from the top of a tower at t =0. Q. 18.
