Statement Based Questions

Q1: Identify the correct statement(s):
(a) A scalar quantity has only magnitude.
(b) A vector quantity has only magnitude.
(c) Velocity is a scalar quantity.
(d) Displacement is always positive.

One Liner Questions: Moving Things, People and IdeasView Answer  One Liner Questions: Moving Things, People and Ideas

Ans: A.
Sol: A is correct because scalar quantities only have magnitude. B, C, and D are incorrect as vector quantities have both magnitude and direction, velocity is a vector quantity, and displacement can be positive, negative, or zero.

Q2: Identify the correct statement(s):
(a) An object in uniform motion covers equal distances in unequal intervals of time.
(b) The first equation of motion relates final velocity, initial velocity, acceleration, and time.
(c) The acceleration due to gravity is constant on Earth.
(d) Displacement can be greater than distance.

One Liner Questions: Moving Things, People and IdeasView Answer  One Liner Questions: Moving Things, People and Ideas

Ans: B, C.
Sol: B is correct as the first equation of motion is v = u + at. C is correct as the acceleration due to gravity is approximately 9.8 m/s². A is incorrect because in uniform motion, distances covered are equal in equal intervals of time. D is incorrect as distance is always equal to or greater than displacement.

Q3: Identify the correct statement(s):
(a) The unit of force is the Newton.
(b) Impulse is the product of force and displacement.
(c) Balanced forces lead to no change in motion.
(d) Friction is a contact force.

One Liner Questions: Moving Things, People and IdeasView Answer  One Liner Questions: Moving Things, People and Ideas

Ans: A, C, D.
Sol: A is correct because the unit of force is the Newton. C is correct as balanced forces lead to no change in motion. D is correct as friction is a contact force. B is incorrect as impulse is the product of force and time, not displacement.

Q4: Identify the correct statement(s):
(a) A body in non-uniform motion covers unequal distances in equal intervals of time.
(b) A velocity-time graph with a straight line indicates uniform motion.
(c) The area under a speed-time graph gives the displacement of an object.
(d) The force of gravity is stronger at higher altitudes.

One Liner Questions: Moving Things, People and IdeasView Answer  One Liner Questions: Moving Things, People and Ideas

Ans: A, B.
Sol:
A is correct as non-uniform motion involves unequal distances in equal intervals of time. B is correct as a straight line in a velocity-time graph indicates uniform motion. C is incorrect as the area under a speed-time graph gives the distance, not the displacement. D is incorrect as gravity is weaker at higher altitudes.

Q5: Identify the correct statement(s):
(a) Force can change the state of motion of a body.
(b) Gravitational force is a contact force.
(c) Velocity is always greater than speed.
(d) Static friction is greater than kinetic friction.

One Liner Questions: Moving Things, People and IdeasView Answer  One Liner Questions: Moving Things, People and Ideas

Ans: A, D.
Sol: A is correct as force can change the state of motion of a body. D is correct as static friction is greater than kinetic friction. B is incorrect as gravitational force is a non-contact force. C is incorrect as speed is always greater than or equal to velocity.
