In rectilinear motion, objects move along a ______.
RRB JE (Stage-II)
01/09/2019 / Shift-III
2019
✓ Answer:AStraight line
Rectilinear motion is motion along a straight line.
242
Which pair always has the same direction?
RRB Group D
15/11/2018 / Shift-III
2018
✓ Answer:BForce and acceleration
The net force and acceleration have the same direction because F_net = ma.
243
A train starts from rest and reaches 90 km/h in 5 minutes with uniform acceleration. Find the distance travelled.
RRB ALP & Technician
13/08/2018 / Shift-III
2018
✓ Answer:D3.75 km
90 km/h = 25 m/s and t = 300 s. s = (0 + 25) × 300/2 = 3750 m = 3.75 km.
244
Starting from rest, Sony reaches 60 m/s on a bicycle in 30 s. Find the acceleration.
RRB Group D
05/12/2018 / Shift-I
2018
✓ Answer:B2 m/s²
a = (60 − 0)/30 = 2 m/s².
245
An object starts from rest with constant acceleration 4 m/s². What is its speed after 8 s?
RRB ALP & Technician
21/08/2018 / Shift-III
2018
✓ Answer:C32 m/s
v = at = 4 × 8 = 32 m/s.
246
Which statement about friction is not true?
RRB NTPC (Stage-I)
27/04/2016
2016
✓ Answer:DRolling friction is much greater than sliding friction; ball bearings considerably reduce friction.
Rolling resistance is generally less than sliding friction, which is why ball bearings reduce friction. A shift is not provided or is cropped in the supplied scan; the available date is retained.
247
If no driving force is applied to a moving object, what can cause it to stop?
RRB Group D
22/09/2018 / Shift-III
2018
✓ Answer:CFriction
Friction is a resisting force that can reduce the object's speed. If no net force at all acted, it would continue at constant velocity.
248
What occurs due to irregularities between two contacting surfaces?
RRB Group D
18/09/2018 / Shift-III
2018
✓ Answer:AFriction
Surface irregularities contribute to resistance to relative sliding, called friction.
249
Frictional force acts ______.
RRB Group D
22/09/2018 / Shift-I
2018
✓ Answer:DOpposite to the direction of force
The source assumes a force trying to slide one surface over another. Friction opposes relative motion or the tendency of relative motion at the contact.
250
When a bicycle accelerates forward, the frictional force on its driven rear wheel acts ______.
RRB SSE
21/12/2014
2014
✓ Answer:BForward
The driven rear wheel pushes backward on the road; static friction from the road acts forward on the wheel. A shift is not provided or is cropped in the supplied scan; the available date is retained.
