Times and Motion Physics 1

The device used to measure the speed of the car is speedometer

A body that moves with a constant speed along a straight line throughout its journey is said to have uniform motion.
A body that moves with changing speed along a straight line throughout its journey is said to have non-uniform motion.

3 x 10⁸ m/s

The two axes are:horizontal axis called the X-axis and one perpendicular axis called the Y-axis

The names given to the axes are X-axis and Y-axis

On the intersection of X-axis and Y-axis represent the origin point O of the graph.Ois the starting point of the graph as it represent the starting values of two parameters

The fastness of the moving of an object is called speed.it can be calculated by dividing the distance covered by time taken.
S = D/T
S.I unit of distance is meter and that of time is second .the unit of speed is m/s
e.g if a boy runs and covers a distance of 50m in 5 sec.the boy runs at a speed of 50/5=10 m/s
suppose if child A and B cross the playground in 5 minutes and 3 minutes repectively.we can say child A moves faster than child B.

When an object covers equal distance in equal intervals of time is said to be in uniform motion.for eg.boy cycling at a speed of 5 m/s on a straight road.

When an object covers unequal distance in an equal interval of time is said to be non-uniform motion.eg.motion of a car moving in a crowded street .

1. collect the data to be plotted and arrange them in a tabular form .
2 . draw X-axis and Y-axis on a graph
3. choose the parameters to represent them along these axis
4. your distance should be on x-axis and your distance should be on y-axis.
5 . plot the data on your graph
6 . draw points with the data given on the right scale(plot the point)
7 . draw a line joining all the dots step-wise
slope m=y/x
distance/time
speed

A body is said to in motion when it changes its position from one place to another.a moving body needs certain time to change its position between any two given points.the motion are of two types uniform motion ,when an object covers equal distance in equal interval of time and non uniform when an objct covers unqual distance in equal interval of time .the time is the passage of a period .we do the work at predefined times.in course of time it has been defined as days , weeks , months and years

Bob passes 10 times through the mean position after five complete oscillations

An ideal simple pendulumn consists of mass m suspended from a string or rod of negligible mass and length L fixed at a point P

The time taken by an oscillating body to complete one oscillation is called time periodthere are various types of time periods-days , week , months and years
