Give reason. If so, give an example. Which one will rise to the greater height? Which one will pass through the point of projection in their downward direction with the greater speed?

Ans: The path followed by a projectile is called trajectory of projectile e. At what angle with the vertical should it be fired to get maximum range? Give an example of a body moving with uniform speed but having a variable velocity and an acceleration which remains constant in magnitude but changes in direction. What is the direction of centripetal force when particle is following a circular path? Two vectors are perpendicular to each other.

## Important Questions for CBSE Class 11 Physics Chapter 3 - Motion in a Straight Line

During past few years, a number of surveys on students were made to better understand their problems regarding their studies and their basic requirement. A river is flowing from west to east at a speed of 5 metre per minute. A man on the south bank of the river, capable of swimming at 10 metre per minute in still water, wants to swim across the river in the shortest time. He should swim in a direction. The velocity of the river in the shortest time. A particle P is sliding down a frictionless hemispherical bowl. At this instant of time, the horizontal component of its velocity is v.

This action cannot be undone. This will permanently delete All Practiced Questions. A ball is thrown upward with a certain speed. It passes through the same point at 3 second and 7 second from the start. The maximum height achieved by the ball is. For the following acceleration versus time graph the corresponding velocity versus displacement graph is.

The motion of an object along a straight line is known as rectilinear motion. 3. What is If an object moving along the straight line covers equal distances in equal intervals of time, then it is said to have Two mark question. 1. Distinguish retardation in the last 5 second (iii) total distance traveled and (iv) average velocity.

## Important Questions on Kinematics for JEE Advanced , Jee Main and NEET

Answer: b In one dimensional motion, the body can have at a time one value of velocity but not two values of velocities. Question 2. Free fall of an object in vacuum is a case of motion with a Uniform velocity b Uniform acceleration c Variable acceleration d Uniform speed Answer: b Uniform acceleration: Free fall of an object in vacuum is a case of motion with uniform acceleration.

It teaches the learners that motion is a change in the position of an object with time. Through this chapter learners will study ways to describe motion without going into the causes of motion. The position of the object can be specified with reference to a conveniently chosen origin. Here the object is referred to as a point object. You also know the methods to derive different equations of motion, find the motion of object at different intervals of time, acceleration and relative velocity of two point objects.

Choose suitable scales and plot the x-t graph of her motion. Each step is 1 m long and requires 1 s. Plot the x-t graph of his motion. Determine graphically and otherwise how long the drunkard takes to fall in a pit 13 m away from the start. What is the speed of the latter with respect to an observer on the ground? What is the retardation of the car assumed uniform , and how long does it take for the car to stop? The driver of B decides to overtake A and accelerates by 1 m s—2.

Students who are weak in physics and do not have a strong core knowledge might find the chapter motion in a straight line difficult. The chapter is full of theories and concepts which can be difficult to grasp and it will be a hindrance for them to achieve good marks. Students need to try and avoid this problem and score good marks in the subject. One of the best ways to overcome such a problem is to study and practice. Students should take time and solve the class 11 physics chapter 3 important questions, an exercise which will help students get the marks they deserve. Students should study theories as well as practice the practical aspects of the chapter.

Problem Set 1: Motion in a Straight Line. AP Physics C Supplementary Problems. Problems selected from Halliday, D., & Resnick, R. (). Fundamentals of.

These important questions will play significant role in clearing concepts of Physics. This question bank is designed by keeping NCERT in mind and the questions are updated with respect to upcoming Board exams. Can a body be said to be at rest as well as in motion at the same time. Yes, rest and motion are relative terms. A body at rest with respect to one body may be in motion with respect to another body.

Голос Фонтейна по-прежнему звучал спокойно, деловито: - Можете ли вы его остановить. Джабба тяжко вздохнул и повернулся к экрану. - Не знаю. Все зависит от того, что ударило в голову автору.  - Он привлек внимание к тексту на экране.

Чего же он ждет.

Такой жирный. Крикливый, тучный, мерзкий немец! - Клушар заморгал, стараясь переменить положение, и, не обращая внимания на боль, продолжал: - Ну чистая скотина, килограмм сто двадцать, не меньше. Он вцепился в эту красотку так, словно боялся, что она сбежит, - и я бы ее отлично понял. Ей-ей.

Неужели он ее трогает. Она не сразу поняла, что он пытается застегнуть верхнюю пуговицу ее блузки. - Сьюзан, - позвал он, задыхаясь.  - Ты должна помочь мне выбраться отсюда. Она ничего не понимала.

Поглощение огромных объемов информации сродни беспорядочным половым связям: какие меры предосторожности ни принимай, рано или поздно подхватишь какую-нибудь гадость.
