The instantaneous acceleration of a particle is the rate at which its velocity is changing at that instant. Here u is the initial velocity, v is the final velocity, a is the accelerations is the displacement travelled by the body and t is the time. Displacement x. Acceleration a. Scalar Quantities:- Scalar quantities are those quantities which require only magnitude for their complete specification. Vector Quantities:- Vector quantities are those quantities which require magnitude as well as direction for their complete specification.
Null Vector Zero Vectors : - It is a vector having zero magnitude and an arbitrary direction. When a null vector is added or subtracted from a given vector the resultant vector is same as the given vector. Dot product of a null vector with any arbitrary is always zero. Cross product of a null vector with any other vector is also a null vector. Co-planar vectors- Vectors situated in one plane, irrespective of their directions, are known as co-planar vectors.
Vector addition Vector addition is commutative. Vector addition is associative. Vector addition is distributive. Magnitude of resultant vector Unit Vector:- Unit vector of any vector is a vector having a unit magnitude, drawn in the direction of the given vector.

NCERT Solutions for Class 11 Physics
Our school does not have SMART Notebooks and I do not have the software to open the notebook files although I would love to be able to present and edit the presentations. Thank you for your help! When you click on the thumbnail option, it still prints full page. Last year was able to choose 1st option. Can you check into it? Robin - I can help you to print the 6 slides per page. Hi, I'm trying to print the 3 slide per page Handouts from the Smart Notebook but it won't load.
There is an image for it. What version of Notebook do you have? For some odd reason it wont let me export the file to PowerPoint. It works for dynamics but not kinematics. I can get you a free version of the software to try out if you let me know if you have a MAC or a PC and what the operating system is. Alexander - thank you for pointing out the error.

Motion is broadly classified into 3 categories : 1. Rectilinear and translatory motion. Circular and rotatory motion. Fig: Example of circular motion. Oscillatory and vibratory motion. When a particle is moving along a straight line, then its motion is a rectilinear motion. Fig: Example of rectilinear motion. C Distance : The length of the actual path traversed by the particle is termed as its distance. D Displacement : The change in position vector of the particle for a given time interval is known as its displacement.
E Average speed and average velocity : Average speed and average velocity are always defined for a time interval. Both have the same SI units, i.
F Instantaneous speed and instantaneous velocity : Instantaneous speed is also defined exactly like average speed i. The instantaneous speed is the speed at a particular instant of time and may have entirly different value than that of average speed. As Dt tends to zero, the ratio defining speed becomes finite and equals to the first derivative of the distance.
The speed at the moment 't' is is called the instantaneous speed at time 't'. On the distance - time plot, the speed is equal to the slope of the tangent to the curve at the time instant 't'. It is equal to the ratio of total displacement and time interval, but with one qualification that time interval is extremely infinitesimally small.
Thus, instantaneous velocity can be termed as the average velocity at a particular instant of time when Dt tend to zero and may have entirely different value that of average velocity, Mathematically. As Dt tends to zero, the ratio defining velocity becomes finite and equals to the first derivative of the position vector.
The velocity at the moment 't' is called the instantaneous velocity or simply velocity at time 't'. The magnitude of average velocity v avg and average speed v avg may not be equal, but magnitude of instantaneous velocity v is always equal to instantaneous speed v. The magnitude of average velocity is A 3.
For the particle calculate. Calculate the average velocity : Sol. If this instant is come in our time limit then distance can be calculated by breaking the integration in two part with modulas. Find out distance travelled by particle from 1 to 3 sec. Average acceleration. Instantaneous acceleration. Acceleration is a vector quantity whose direction is same as that of change in velocity vector. Integrating equation 1 within the above limits of time and velocity, we get.
Integrating equation 3 within the above limits of time and distance, we get. Third equation of motion : By the definitions of acceleration and velocity.
NCERT Books Class 11 Physics
Integrating equation 5 within the above limits of velocity and displacement, we get. Fourth equation of motion : By definition of velocity. Integrating equation 7 within the above limits of time and distance, we get.
It then runs at constant velocity and finally brought to rest in m with a constant retardation.
