Power derived quantity

Back 1

Any unit that are not base units - derived. Base: MLTETAL. Derived come from performing mathematical calculations or operations onna base unit.

Power- f acting on mass to produce work. VI. But always product of 2 factors. So, derived from other measurements.

Back 2

V.C= 1 smallest division of main scale/no of vernier divisions = s/n

n= s/VC

Back 5

Newt 3rd law.

Ground also exerts force like us. Equal and opposite force creates acceleration. Not possible to exert force properly on not hard ground bc sand or mud will be displaced. So reaction force is less.

Front 6

Uniform v is uniform speed uniform speed is not uniform v

Back 6

Distance is magnitude of velocity

So magnitude same

But if speed uniform magnitude might not be same

Power of different fundamental quantities in a quantity

Front 8

Velocity and acceleration 0

Back 8

Throwing up a body, v 0 at highest point but g still working

Front 9

Velocity changing but not speed

Back 9

Front 10

Time is equal for throwing and falling

Back 10

The time taken for an object to travel upward and downward is equal when thrown vertically, assuming ideal conditions and no air resistance, due to the symmetry of its motion. Initial v and gravitational acceleration remain constant and the object covers the same vertical distance in both directions consequently the time taken to reach the maximum height is equal to the time taken to fall back to the starting point.

V.sc important

Back 11

By offering finer divisions than the primary scale it allows for highly accurate readings down to fractions of a unit. Crucial in fields like engineering science and manufacturing. Exact measurements are essential of a quality control precise design and scientific experiments. Reduces human error in measurement ensuring consistent and reliable data. Pivotal role in achieving accuracy thereby contributing to the reliability and success of various industries and scientific endeavors.

Front 12

Third law Fall

Back 12

As time increases the distance and object falls increases quadratically for example if an object falls for 1 second it will cover A certain distance but if it falls for 2 seconds it will cover for times that distance and if it falls for 3 seconds it will cover 9 times the initial distance and so on.

Dimension

Back 13

The exponent of the basic quantities present in a physical quantity is called the dimension of the quantity

Front 14

Periodic motion condition

Back 14

If the acceleration of the motion executing particle is proportional to its displacement from the equilibrium position and is always directed towards the mean position.

Front 15

Frictional force

Back 15

Frictional force is the resistance encountered by two objects in contact is the attempt to move relative to each other caused by the interlocking of surface irregularities
