m / s2 is the unit of :
speed
acceleration
displacement
time
What type of motion is the motion of tip of second's hand of a watch?
Uniform motion
Accelerated motion
Non uniform motion
None of these
The position of a particle going along a straight line is x1 = 50 m at 10.30a.m. and x2 = 55 m at 10.35 a.m.The displacement between 10.30 a.m and 10.35 a.m. is :
2 m
5 m
7 m
9 m
A car covers the first half of the distance between two places at a speed of 40 km/hr and second half at 60 km/hr. The average speed of the car is :
100 km/hr
50 km/hr
48 km/hr
52 km/hr
The ratio of the total distance travelled by the body to the total time of journey is called
Speed
Average speed
Acceleration
Average acceleration
A bus increases its speed from 20km / h to 50km / h in 10seconds. Its acceleration is:
30m / s2
3m / s2
18m / s2
0.83m / s2
Example for oscillatory motion is
Rotation of the Earth
Revolution of the Earth
Motion of a simple pendulum
All the above
Speed =
Distance / time
Distance × time
time / distance
A body has a uniform motion when
it covers equal distances in unequal intervals of time
it covers unequal distances in equal intervals of time
it covers equal distances in equal intervals of time
The speed of a moving object is determined to be 0.06 m/s. This speed is equal to
2.16 km/h
1.08 km/h
0.216 km/h
0.0216 km/h
