XI Physics_New Chapter-4_Laws of Motion [True or False Statement Questions]Sl # True or False Statements from Laws of Motion - High Order Thinking Skills True/False
1 A bullet fired by a gun can easily penetrate human tissue, causing injury.
A bullet fired by a gun can easily pierce human tissue before it stops, resulting in minimal
2
damage.
3 A bullet fired from a gun leads to a decrease in the total momentum of the system.
A small force acting for a long time to produce a finite change in momentum is referred to as
4
an impulsive force.
5 A smaller force is needed to push a truck than a car to bring them to the same speed in the same time.
6 A spring's force is proportional to its compression or elongation.
7 Acceleration can arise even when there's no net external force acting on an object.
8 Action and reaction forces act on different bodies, not on the same body.
9 Action and reaction forces act on the same body, not on different bodies.
Action and reaction forces can be canceled out if they have the same magnitude and opposite
10
direction.
11 Action-reaction forces act on different bodies and are equal and opposite.
An astronaut in interstellar space accelerates indefinitely due to the absence of nearby
12
gravitational forces.
An impulsive force is a large force acting briefly, resulting in a finite change in momentum.
13
An object in uniform motion maintains constant velocity if no net external force acts upon it.
14
Aristotle's law of motion states that a body will stop moving unless an external force is
15
applied to it.
Aristotle's view that a force is necessary to keep a body in uniform motion is completely
16
accurate and supported by modern physics.
17 Bodies in motion can come to a stop without any external force acting upon them.
Bodies in uniform motion require no external force to stay in motion; inertia is irrelevant.
18
Considering all forces acting on a system while solving problems can lead to inaccurate results
19
and should be avoided.
20 Contact forces arise from bodies in contact and include friction, tension, etc.
Drawing free-body diagrams is unnecessary when solving mechanics problems, as they tend
21
to confuse the understanding of forces.
Equilibrium equations imply that the components of forces along x, y, and z directions must
22
not sum up to zero.
23 Equilibrium of a particle is only applicable when the particle is at rest.
Equilibrium of a particle means that the net external force on the particle is always non-zero.
24
Equilibrium under the action of forces F1, F2,... Fn is achieved when they can't be represented
25
by the sides of a closed n-sided polygon.
26 Every action has an equal and opposite reaction, as stated by Newton's third law.
27 Every object on Earth experiences the force of gravity due to the Earth.
28 External agencies (e.g., gravity, magnetism) can exert force on a body from a distance.
External agencies cannot exert force on bodies from a distance; direct contact is required.
29
30 External force is necessary to initiate motion or bring a body to a stop.
External force needed to alter state of motion; inertia keeps bodies in their current state.
31
32 External forces are needed to counteract friction for uniform motion.
For applying the second law of motion, there is no conceptual distinction between inanimate
33
and animate objects.
