Physics Chapter 1 (Topic 9 : Justify Vector Quantities)
Justify that displacement, force, weight, velocity, acceleration, momentum, electric field strength and gravitational field strength are vector quantities.
1 / 36
Why is displacement considered a vector quantity?
Reasoning: Displacement describes distance with a specific direction.
2 / 36
Force is a vector quantity because it:
Reasoning: Force acts in a specific direction.
3 / 36
Weight is classified as a vector quantity because it:
Reasoning: Weight always acts downward due to gravity.
4 / 36
Velocity differs from speed because velocity:
Reasoning: Velocity includes direction of motion.
5 / 36
Why is acceleration a vector quantity?
Reasoning: Acceleration depends on change in velocity (vector).
6 / 36
Momentum is a vector quantity because it depends on:
Reasoning: Momentum = mass × velocity
7 / 36
Electric field strength is a vector quantity because it:
Reasoning: Electric field has directional force effect.
8 / 36
Gravitational field strength is vector because it:
Reasoning: It always points toward the center of mass.
9 / 36
Which of the following is NOT a vector quantity?
Reasoning: Mass has only magnitude.
10 / 36
What makes displacement different from distance?
Reasoning: Displacement is directional.
11 / 36
Which statement best describes weight?
Reasoning: Weight always acts downward.
12 / 36
Momentum direction is always along:
Reasoning: Momentum depends on velocity direction.
13 / 36
Which of the following is a vector in circular motion?
Reasoning: Velocity direction keeps changing.
14 / 36
Why is electric field strength considered a vector?
Reasoning: Field direction is defined by force direction.
15 / 36
Which quantity changes direction when motion changes?
Reasoning: Velocity depends on direction.
16 / 36
Acceleration is a vector because it depends on:
Reasoning: Velocity change includes direction change.
17 / 36
Which is true about gravitational field strength?
Reasoning: Gravity always pulls inward.
18 / 36
Which pair contains only vector quantities?
Reasoning: Both have magnitude and direction.
19 / 36
Why is force a vector quantity?
Reasoning: Force direction affects motion.
20 / 36
Which is NOT required to define a vector quantity?
Reasoning: Emotions are irrelevant in physics.
21 / 36
Which quantity is vector in projectile motion?
Reasoning: Velocity has changing direction.
22 / 36
Which statement about vectors is correct?
Reasoning: This is the definition of vector.
23 / 36
Weight is always directed:
Reasoning: Gravity pulls objects downward.
24 / 36
Why is momentum not scalar?
Reasoning: Velocity direction defines momentum direction.
25 / 36
Which of the following is a vector quantity in physics experiments?
Reasoning: Force has direction.
26 / 36
Electric field direction is defined by:
Reasoning: Standard definition of electric field direction.
27 / 36
Which quantity is vector in nature during free fall?
Reasoning: Gravity has direction toward Earth.
28 / 36
Which statement correctly differentiates scalar & vector quantities here?
Reasoning: This defines vector quantities.
29 / 36
Why is displacement vector while distance is scalar?
Reasoning: Displacement is direction-dependent.
30 / 36
Reasoning: Energy is scalar.
31 / 36
Which quantity always points toward the center of Earth?
Reasoning: Weight acts downward due to gravity.
32 / 36
Why is acceleration a vector in circular motion?
Reasoning: Direction is always changing.
33 / 36
Which of the following best defines a vector quantity?
34 / 36
