The condition in which a body covers equal distance in an equal interval of time is known to be uniform velocity. In equation(d = v t) v is the average velocity of a body during time t. iI both its magnitude and direction do not change with time then it can be said that the body is at uniform velocity.

## Which is the third chapter of physics class 11?

NCERT Solutions for Class 11 Physics Chapter 3 Motion in a Straight Line.

## What are the important topics in motion in a straight line?

Motion in a Straight Line: Acceleration, Velocity, Displacement and Speed.

## Is motion in a 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.

## Which chapter is motion in straight line Class 11?

Motion is one of the significant topics in physics.

## What is rest physics?

Rest: An object is said to be at rest if it does not change its position with respect to its surroundings with time. Motion: An object is said to be in motion if the position changes with respect to it surrounding and time.

## How many types of motion are there?

According to the nature of the movement, motion is classified into three types as follows: Linear Motion. Rotary Motion. Oscillatory Motion.

## What is the SI unit of speed?

The SI unit of speed is given in terms of basic units of distance and time. Thus, the SI unit of speed is metre per second or m/s.

## What are the 3 equation of motion?

The three equations are, v = u + at. vยฒ = uยฒ + 2as. s = ut + ยฝatยฒ

## Which of the following is an equation of motion of a body Mcq?

v is final velocity, u is initial velocity, t is time, a is acceleration, s is the distance travelled. Explanation: u = v + at is not the equation of motion. โ v2 = u2 + 2as is the form of equation of motion.

## Which of the following remains constant if a body travels with constant acceleration *?

But the speed can be constant if the acceleration produced by the force is only change the direction of motion. For example in uniform circular motion, acceleration is non-zero, velocity is not constant but speed is constant.

## Is kinematics 1d important for JEE?

Kinematics is considered an important as well as an easy chapter of Mechanics that is a part of the JEE Mains syllabus. The students usually find the numerical problems in this chapter very interesting. This chapter is very essential as it is a prerequisite to all other chapters of Mechanics.

## What is velocity time graph?

A velocity-time graph shows the speed and direction an object travels over a specific period of time. Velocity-time graphs are also called speed-time graphs. The vertical axis of a velocity-time graph is the velocity of the object. The horizontal axis is the time from the start.

## What is circular motion class 11?

What is Circular Motion? A body is said to be in Circular Motion when the body moves at a definite distance from a fixed point along a circular path. The fixed point acts as the centre, and the fixed distance acts as the radius of the circular path the body is travelling.

## What is the SI unit of rest?

No , there is no SI unit for rest although rest means that the object is not moving with respect to any other object. As rest is dimensionless it does not have any unit either.

## What are states of motion?

The state of motion of an object is defined by its velocity – that is speed with a direction. Force is the agent which can change the state of motion of the object.

## What is relative point?

A relative maximum point is a point where the function changes direction from increasing to decreasing (making that point a “peak” in the graph). Similarly, a relative minimum point is a point where the function changes direction from decreasing to increasing (making that point a “bottom” in the graph).

## What are the 4 basic types of motion?

- linear.
- rotary.
- reciprocating.
- oscillating.

## What are the types of force?

- Gravitational force.
- Electric force.
- Magnetic force.
- Nuclear force.
- Frictional force.

## What are the 7 types of motion?

- Oscillatory Motion.
- Rotational Motion.
- Translational Motion.
- Periodic Motion.
- Circular Motion.
- Linear Motion.
- Uniform Motion.
- Non-Uniform Motion.

## Which is unit of force?

The SI unit of force is the newton, symbol N. The base units relevant to force are: The metre, unit of length โ symbol m. The kilogram, unit of mass โ symbol kg.

## What are the 7 basic SI units?

- Length – meter (m)
- Time – second (s)
- Amount of substance – mole (mole)
- Electric current – ampere (A)
- Temperature – kelvin (K)
- Luminous intensity – candela (cd)
- Mass – kilogram (kg)

## What is CGS unit of heat?

In the CGS system, heat is expressed in the unit of calories which is further said to be the heat energy needed to increase the temperature of 1 gm of clean water by one degree Celsius. Sometimes kilocalorie (kcal) is referred to as a unit of heat where 1 kcal = 1000 cal.

## What is Ke formula?

Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

## What is first law motion?

Newton’s first law: the law of inertia Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
