TOUGH AND CHALLENGING TOPICS
Dot product of two vectors can be zero. Perpendicular vectors have a zero dot product (no
1
projection on each other).
Dot product is used to calculate work done. Dot product of force and displacement vectors considers
2
both direction and magnitude.
Uniform circular motion: constant acceleration Though speed is constant, direction changes in uniform
3 towards center. circular motion, requiring centripetal acceleration inwards.
Conservation of angular momentum applies in Total angular momentum of a closed system remains
4
closed systems. constant without external torques.
Non-zero torque causes a rigid body to rotate. Torque, the rotational equivalent of force, can cause
5
angular acceleration, leading to rotation.
Unbalanced torque can cause a rigid body to When the net torque is not zero, the body rotates until a
6
topple. new equilibrium position (possibly toppling) is reached.
Oblique collisions involve momentum transfer in Incoming momenta in oblique collisions are not aligned
7
different directions. due to the angle of impact.
Center of mass: point where all mass is The center of mass is a theoretical point representing the
8
considered concentrated. average location of all mass in an object.
Elastic collisions conserve kinetic energy. Minimal energy dissipation in elastic collisions allows
9
objects to separate with the same total kinetic energy.
Inelastic collisions decrease total kinetic energy. Inelastic collisions involve factors like friction that cause
10
objects to lose kinetic energy upon collision.
Coefficient of restitution measures collision This ratio of relative speeds after and before a collision
11 elasticity. indicates energy loss in inelastic collisions (0 < coefficient
< 1).
Fluid statics analyzes fluids at rest. This branch of fluid mechanics focuses on pressure forces
12
within stationary fluids.
Viscosity resists fluid flow. This internal friction within a fluid opposes the movement
13
of its neighboring layers.
Newton's law relates shear stress and shear rate. It describes the proportionality between applied shear
14 stress (deformation force) and resulting shear rate
(deformation) in a fluid.
Simple pendulum oscillates with a specific The period of a simple pendulum depends on its length and
15
period. the acceleration due to gravity.
RMS speed is a statistical measure of gas It calculates the average speed of gas molecules by
16
molecule speeds. considering the squares of their individual speeds.
Degrees of freedom represent microscopic These refer to the independent ways (like translation and
17 energy storage. rotation) a system can store energy at the microscopic
level.
Specific heat capacity determines temperature This material property indicates the amount of heat energy
18 change. needed to raise 1 gram of a substance's temperature by 1
degree Celsius.
Mean free path is the average distance between It represents the average distance a gas molecule travels
19
gas molecule collisions. before encountering another molecule.
Kinetic theory of gases explains ideal gas law. This model proposes that gas molecules in constant
20 motion collide with each other and container walls,
explaining pressure-volume-temperature relationships.
Ideal gas equation relates pressure, volume, This mathematical relationship describes the behavior of
21 temperature, and quantity. ideal gases, assuming negligible interactions between
molecules.
Gravitational potential energy depends on mass This energy increases with an object's mass and distance
22
and distance. from Earth due to the gravitational pull.
Electric field exerts force on charged particles. Electric fields interact with electric charges, exerting forces
23 that attract opposite charges and repel like charges.
The electric potential at a point is higher near a Electric potential indicates the work done per unit charge
24 positive charge than near a negative charge. to bring it from infinity, and positive charges repel,
requiring more work.
In a light bulb, increasing the voltage across the Ohm's law states current is proportional to voltage, and
25
filament will result in a greater current. resistance in a filament is relatively constant.
