1.
A particle starts from rest with uniform acceleration. The distance covered in the first 4 s is
2.
A body moving with velocity 15 m/s is uniformly accelerated at 3 m/s². Its velocity after 5 s is
3.
The area under a velocity-time graph is negative when
4.
A displacement-time graph parallel to the time axis represents
5.
A particle moves with constant acceleration. The velocity-time graph is
6.
If the velocity of a particle becomes double while acceleration remains constant, the slope of the velocity-time graph
7.
The SI unit of retardation is
8.
Assertion (A): Distance travelled is always greater than or equal to the magnitude of displacement. Reason (R): Displacement is the shortest distance between initial and final positions.
9.
Assertion (A): A body moving with constant speed may have non-zero acceleration. Reason (R): Acceleration changes whenever the direction of velocity changes.
10.
A body moving along a straight line returns to its starting point. Then
