MCQs
Q1. Which of the following effects is not caused by a force?
(a) Change in shape
(b) Change in speed
(c) Change in direction
(d) Change in temperature
Show Answer
Answer: (d)
Explanation: Force can change the shape, speed, or direction of motion but does not directly affect temperature.
Q2. Which of the following is an example of balanced forces?
(a) A book kept on a table
(b) A football in motion
(c) A car accelerating
(d) A falling apple
Show Answer
Answer: (a)
Explanation: When a book rests on a table, the gravitational force downward is balanced by the table’s normal reaction.
Q3. What type of force is friction?
(a) Non-contact force
(b) Balanced force
(c) Contact force
(d) Magnetic force
Show Answer
Answer: (c)
Explanation: Friction is a contact force that arises when two surfaces are in contact and resist motion.
Q4. Which law of motion explains the recoil of a gun?
(a) First law
(b) Second law
(c) Third law
(d) Law of inertia
Show Answer
Answer: (c)
Explanation: The gun recoils due to Newton’s third law: for every action, there is an equal and opposite reaction.
Q5. An object at rest remains at rest due to its:
(a) Friction
(b) Inertia
(c) Weight
(d) Speed
Show Answer
Answer: (b)
Explanation: Inertia is the property of an object to resist changes in its state of motion or rest.
Q6. The SI unit of force is:
(a) dyne
(b) newton
(c) pascal
(d) kilogram
Show Answer
Answer: (b)
Explanation: The SI unit of force is newton (N), defined as the force required to give a 1 kg mass an acceleration of 1 m/s².
Q7. Which equation correctly relates force, mass, and acceleration?
(a) F = ma
(b) F = m/v
(c) F = m + a
(d) F = a/m
Show Answer
Answer: (a)
Explanation: Newton’s second law of motion gives F = ma, where F is force, m is mass, and a is acceleration.
Q8. Momentum is a product of:
(a) Force and time
(b) Mass and acceleration
(c) Mass and velocity
(d) Acceleration and time
Show Answer
Answer: (c)
Explanation: Momentum (p) is the product of mass (m) and velocity (v), i.e., p = mv.
Q9. Which statement is true about action and reaction forces?
(a) They act on the same object
(b) They are equal and act on different objects
(c) Reaction is smaller than action
(d) They cancel each other
Show Answer
Answer: (b)
Explanation: Action and reaction forces are equal in magnitude and opposite in direction, but they act on different objects.
Q10. The force that slows down a moving object is:
(a) Normal force
(b) Friction
(c) Magnetic force
(d) Balanced force
Show Answer
Answer: (b)
Explanation: Friction opposes motion and slows down or stops moving objects.
Q11. What will happen to an object moving with constant velocity when a net unbalanced force acts on it?
(a) It will stop
(b) It will continue at same speed
(c) It will accelerate
(d) It will change shape
Show Answer
Answer: (c)
Explanation: An unbalanced force causes a change in motion, resulting in acceleration.
Q12. Which factor affects inertia of a body the most?
(a) Its volume
(b) Its shape
(c) Its mass
(d) Its speed
Show Answer
Answer: (c)
Explanation: Inertia depends on mass; more massive objects have greater inertia.
Q13. Why is it difficult to walk on a smooth surface?
(a) Less weight
(b) Lack of friction
(c) Gravitational force
(d) Less pressure
Show Answer
Answer: (b)
Explanation: Friction provides the grip for walking. A smooth surface has less friction and makes walking difficult.
Q14. A ball is dropped from a height and bounces back. What kind of motion does it show?
(a) Uniform motion
(b) Oscillatory motion
(c) Translational motion
(d) Linear motion
Show Answer
Answer: (b)
Explanation: The ball shows oscillatory motion as it moves up and down repeatedly.
Q15. Which law of motion explains why passengers jerk forward when a bus suddenly stops?
(a) Newton’s third law
(b) Law of gravitation
(c) Newton’s first law
(d) Law of conservation of energy
Show Answer
Answer: (c)
Explanation: Due to inertia, the passenger’s body tends to remain in motion when the bus suddenly stops.
Q16. A bullet fired from a gun exerts recoil on the gun due to:
(a) Inertia
(b) Action-reaction
(c) Momentum
(d) Balanced forces
Show Answer
Answer: (b)
Explanation: The recoil is due to Newton’s third law of motion: for every action, there is an equal and opposite reaction.
Q17. What is the direction of frictional force?
(a) Along motion
(b) Opposite to motion
(c) Perpendicular to motion
(d) Random
Show Answer
Answer: (b)
Explanation: Friction always acts in the direction opposite to that of motion.
Q18. A runner pushes the ground with his foot. The ground pushes back with:
(a) Less force
(b) Equal force
(c) Greater force
(d) No force
Show Answer
Answer: (b)
Explanation: According to Newton’s third law, the ground exerts an equal and opposite force on the runner.
Q19. What is the momentum of a 5 kg object moving at 10 m/s?
(a) 50 N
(b) 15 kg m/s
(c) 50 kg m/s
(d) 0.5 kg m/s
Show Answer
Answer: (c)
Explanation: Momentum = mass × velocity = 5 kg × 10 m/s = 50 kg m/s.
Q20. The SI unit of momentum is:
(a) kg m/s
(b) kg m/s²
(c) newton
(d) joule
Show Answer
Answer: (a)
Explanation: The SI unit of momentum is kilogram meter per second (kg m/s).
