Speed and Velocity
I. Speed Formula-
Tips of Speed-
S.I. unit or meters per second.
Dimensions=
Speed is a scalar quantity.
E.g: A body covers a distance of 18m in 1 sec
Using the formula of speed.
II. Average Speed and Instantaneous Speed
Average Speed Formula-
,
E.g. A body covers a total distance of 50 m with variable speed in 5 sec.
Average Speed = 10 m/s
Tips for average speed-
If an object or body covers s1 distance in t1 time and s2 distance in t2 time then average speed is calculated by the
Formula-
Instantaneous Speed-
It is the speed at that particular instant or small interval of time.
Formula-
III. Velocity
Rate of change of displacement with time.
Formula-
Tips For Velocity-
S.I. unit m/s
Dimensions-
Velocity is a vector quantity.
Velocity is also called speed in a definite (particular) direction.
IV. Average Velocity and Instantaneous Velocity
Average Velocity- Formula-
,
Instantaneous Velocity Formula-
Work done by a constant force-
The scalar product of the force vector () and the displacement vector ()
The product of the magnitude of force magnitude of displacement and cosine of the angle between them
If the number of forces , are acting on a body and it shifts from position vector to position vector
Then
Work done by a variable force
Force is a vector quantity. So it has a magnitude as well as direction. A variable force means when its magnitude its direction or both varies with position.
And work done by the variable force is given by -
Where is a variable force and is a small displacement
Kinetic energy
Where
Work-energy theorem-
Net work done by all the forces acting on a particle is equal to the change in its kinetic energy.
Where
Relation of kinetic energy with linear momentum
Where
Change in potential energy -
The change in potential energy between any two points is defined as the work done by the associated conservative force in displacing the particle between these two points without any change in kinetic energy.
......(1)
Where,
We can define a unique value of potential energy only by assigning some arbitrary value to a fixed point called the reference point.
Power
Average power-
Instantaneous power-
Where,
i.e. power is equal to the scalar product of force with velocity
