Short Tricks: Motion in a Straight Line Video Lecture | Physics Class 11 - NEET

Q: 4. What are the equations of motion in a straight line?

Ans. The equations of motion in a straight line are:- v = u + at (final velocity = initial velocity + acceleration × time)- s = ut + (1/2)at^2 (displacement = initial velocity × time + (1/2)acceleration × time squared)- v^2 = u^2 + 2as (final velocity squared = initial velocity squared + 2 × acceleration × displacement)- s = ((u + v)/2) × t (displacement = average velocity × time)- v = u + 2as (final velocity = initial velocity + 2 × acceleration × displacement)

FAQs on Short Tricks: Motion in a Straight Line Video Lecture - Physics Class 11 - NEET

1. What is motion in a straight line?

Ans. Motion in a straight line refers to the movement of an object along a straight path. It can be either uniform, where the object covers equal distances in equal intervals of time, or non-uniform, where the object covers unequal distances in equal intervals of time.

2. What is the difference between distance and displacement?

Ans. Distance is the total path covered by an object, whereas displacement is the shortest path between the initial and final positions of the object. Distance is a scalar quantity, while displacement is a vector quantity with both magnitude and direction.

3. How is speed different from velocity?

Ans. Speed is the distance covered by an object per unit time, whereas velocity is the displacement of an object per unit time. Speed is a scalar quantity, while velocity is a vector quantity that includes both magnitude and direction.

4. What are the equations of motion in a straight line?

Ans. The equations of motion in a straight line are: - v = u + at (final velocity = initial velocity + acceleration × time) - s = ut + (1/2)at^2 (displacement = initial velocity × time + (1/2)acceleration × time squared) - v^2 = u^2 + 2as (final velocity squared = initial velocity squared + 2 × acceleration × displacement) - s = ((u + v)/2) × t (displacement = average velocity × time) - v = u + 2as (final velocity = initial velocity + 2 × acceleration × displacement)

5. What is the significance of the slope of a distance-time graph in motion?

Ans. The slope of a distance-time graph represents the speed of an object. A steeper slope indicates a higher speed, while a gentler slope indicates a lower speed. If the slope is zero, it means the object is at rest. The positive or negative sign of the slope indicates the direction of motion.
