Practice Force and Laws of Motion RRB PYQ questions from Railway examinations, including RRB NTPC PYQ, RRB Group D PYQ, RRB JE PYQ, RRB ALP PYQ and RRB Technician PYQ. This topic-wise Physics question set covers important concepts related to force, Newton’s laws of motion, inertia, acceleration, momentum and the effect of force on the motion of objects.
The Force and Laws of Motion RRB PYQ collection is useful for candidates preparing for Railway examinations and revising important Physics concepts through previous year questions. Questions from this topic can include both conceptual and numerical problems, helping you understand the application of Newton’s laws and improve your problem-solving skills.
Whether you are preparing for RRB NTPC Force and Laws of Motion PYQ, RRB Group D Force and Laws of Motion PYQ, RRB JE Force and Laws of Motion PYQ, RRB ALP Force and Laws of Motion PYQ, or RRB Technician Force and Laws of Motion PYQ, practice these questions regularly to strengthen your Railway Physics preparation.
261
A high-speed vehicle may skid on a road curve due to ______.
RRB RPF Constable
06/03/2025 / Shift-II
2025
✓ Answer:BCentrifugal force
The source selects centrifugal force. In an inertial frame, skidding occurs when available friction cannot provide the centripetal force needed for the turn.
262
An object starts from rest and reaches 5 m/s in 2 s. Find its acceleration.
RRB Group D
19/09/2018 / Shift-I
2018
✓ Answer:C2.5 m/s²
a = (5 − 0)/2 = 2.5 m/s².
263
Which example describes uniform circular motion?
RRB ALP (Stage-I)
29/11/2024 / Shift-II
2024
✓ Answer:DMotion of a clock hand
An ideal clock hand moves at constant angular speed, and a point on it follows a circular path.
264
Which is not a valid equation for uniformly accelerated motion?
RRB Group D
02/11/2018 / Shift-III
2018
✓ Answer:Cv − u = a + t
The correct relation is v − u = at, not a + t.
265
A child throws a 1/4 kg ball vertically upward. His hand moves upward by 10 cm and the ball leaves it at 2 m/s. Find the constant force exerted to throw the ball.
RRB Group D
24/10/2018 / Shift-III
2018
✓ Answer:D5 N
The source gives D using a = v²/(2s) = 20 m/s² and ma = 5 N. This is the net force; including gravity, the hand's upward force is m(a + g) ≈ 7.5 N. The printed key is retained.
266
Starting from rest, Sony reaches 6 m/s on a bicycle in 30 s. Find the acceleration.
RRB Group D
03/12/2018
2018
✓ Answer:B0.2 m/s²
a = (6 − 0)/30 = 0.2 m/s². A shift is not provided or is cropped in the supplied scan; the available date is retained.
267
A car stops when brakes are applied mainly because of ______.
