Define One Dimension Motion
When a body moves along a straight line path, its motion is said to be one dimension motion.
One dimension motion is also called as _______________
Rectilinear motion
A body starts from the rest and acquires a velocity of 10m/s in 2s. Find the
acceleration.
5m/s
Momentum is a scalar quantity. (True/False)
False
What is the S.I. unit of speed?
m/s
A car starting from rest accelerates uniformly to acquire a speed 20 km/h in 30 min. The distance traveled by car in this time interval will be?
5km
A train moving with a velocity of 20m/s is brought to rest by applying brakes in 5s.
Calculate the retardation.
4m/s^2
Arrange the following speeds in increasing order:
10 ms^-1, 1km min^-1, 18 km h^-1
The increasing order is 18 km h^-1, 10 ms^-1, 1 km min^-1
Can displacement be zero even if distance is not zero?
Yes
S.I. unit of retardation.
ms^-2
