|| This is indicated by grey digital clock.

This clock shows the instantaneous time of the moving car.
|-
|| At the bottom point to ''' x''' and ''' v '''values.
|| Observe that, the values of '''x ''' and '''v''' are changing continuously.

It means that the car is in uniform motion.

And it will continue to be in motion until an external force is applied.

This is due to '''Newton's first law of motion'''.
|-
|| Click on the ''' Pause''' button and uncheck the '''Slow motion''' check-box.
|| Click on the '''Pause''' button and uncheck the '''Slow motion''' check-box.
|-

|-
||
|| Let us verify the values of '''position''' and '''velocity''' using equations of motion.
|-
|| '''Slide Number 8'''

'''Equations of Motion'''

'''v = v0 + at '''

'''x = x0 + v0 t + 1/2at2 '''

'''v2 = v02 + 2 a (x − x0)'''

'''v0 '''and '''v''' are the initial and final velocities.

'''x0''' and '''x''' are the intial and final positions.

|-
|| '''Slide Number 9'''

'''Tabular column (write the measured values)'''.
||

We will note the measured and calculated values in the table.
|-
|| Point to red and green barrier.
|| Next we will use both green and red barrier to measure position and velocity.
|-

|-
||
|| Now we will calculate the values using equations of motion.
|-
|| '''Slide Number 10'''

'''Equations of Motion'''

'''v = v0 + at '''

'''<nowiki>= 5 + 2 * 1.531</nowiki>'''

'''<nowiki>=8.06 m/s</nowiki>'''

|| Let us calculate velocity using the first equation of motion.

Substitute the values of acceleration, time and initial velocity shown in the '''App '''in the equation.

8.06''' m/s''' is the calculated value of velocity.
|-
|| '''x = x0 + v0 t + 1/2at2'''

'''<nowiki>= 5 + 5 * 1.531 + 1/2 * 2 * (1.531)</nowiki>2'''

'''<nowiki>= </nowiki>14.99 m.'''
|| Let us calculate the '''position''' using the second equation of motion.

Similarly substitute the values shown in the '''App'''.

14.99 '''m '''is the calculated value of the position.
|-
|| Point to the value of position in the '''App.'''
|| Observe that the values of position and velocity are approximately equal to the measured values.
|-
|| '''Slide Number 11'''
