What happens when a body moves in uniform velocity?
u > v
v > u
u = v
u = 2
Which one of the following equation of motion is correct?
u = v + at
v = u - at
v = u + at
u = v - at
Which of the physical quantity can be calculated by using the formula
u + v
2
Relative velocity
Speed
Average velocity
Acceleration
What is the correct formula to calculate acceleration?
u + v
2
v - u
t
v - u
2
u - v
t
If two bodies move in same direction, their relative velocity is equal to
VAB = VA + VB
VAB = VA - VB
VAB =VA X VB
VAB = VA ÷ VB
What happens a body starts to move from rest?
Its u = v
Its u > v
Its u = 0
None of these
What is the SI unit of acceleration?
m/s
m
m / s2
None of these
Which of the following device is used to measure the speed of a body?
Anemometer
Barometer
Speedogauge
Speedometer
What happens when a body gains acceleration?
Its speed decreases.
Its speed does not change.
Its initial velocity and final velocity becomes equal.
Its speed increases.
Which one of the following has uniform velocity?
Motion of Hands of clock
Motion of Planets around the sun
Motion of stars
All of them
When does a body have zero acceleration?
When it moves in uniform velocity
When its u > v
When its final velocity is zero
When its initial velocity is zero.
If a car starts to move from rest and gains a velocity of
25 m/s after 10 sec, find its acceleration.
2 m/s2
