Click to see Hint ⬇
This term is related to the orbital dynamics of celestial bodies.
Aphelion - Aphelion is the point in a celestial body's orbit where it is farthest from the Sun, while perihelion is the point where it is closest to the Sun.

Question 7:

## What is the name of the process by which a black hole emits radiation and gradually loses mass?

Click to see Hint ⬇
This phenomenon is named after a renowned physicist.
Hawking radiation - Hawking radiation is a theoretical process proposed by Stephen Hawking, where black holes emit radiation and gradually lose mass over very long periods of time.

Question 8:

## What is the SI unit for force?

Click to see Hint ⬇
This unit is named after a famous physicist.
Newton - The Newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared.

Question 9:

## Which of the following is a measure of an object's resistance to changes in motion?

Click to see Hint ⬇
This property is related to mass.
Inertia - Inertia is directly proportional to an object's mass, meaning the greater the mass, the greater the inertia.

Question 10:

## Which of the following is a simple machine used to lift or move objects?

Click to see Hint ⬇
It involves a system of ropes and wheels.
Pulley - Pulleys reduce the amount of force needed to lift heavy objects by distributing the load over multiple ropes or chains.

Question 11:

## Which of the following is a measure of the force of gravity on an object?

Click to see Hint ⬇
This measurement can change in different gravitational fields.
Weight - Weight is directly proportional to an object's mass and the acceleration due to gravity.

Question 12:

## Which of the following laws states that for every action, there is an equal and opposite reaction?

Click to see Hint ⬇
This law deals with interactions between objects.
Newton's Third Law - This law explains the principle behind propulsion systems, recoil, and many other physical phenomena.

Question 13:

## What is the term for the force that opposes the relative motion or tendency of such motion of two surfaces in contact?

Click to see Hint ⬇
It is the force that makes it difficult to slide objects across a surface.
Friction - Friction is the force that resists the relative motion or tendency of such motion of two surfaces in contact. It is caused by the irregularities of the surfaces and plays a crucial role in various mechanical systems.

Question 14:

## What is the SI unit for work and energy?

Click to see Hint ⬇
It is named after an English physicist.
Joule - The joule is the unit of work or energy in the International System of Units (SI). It is defined as the work done by a force of one newton acting over a distance of one meter.

Question 15:

## What is the term for the point in a system where the potential energy is at a minimum?

Click to see Hint ⬇
It is the state of minimum potential energy in a system.
Equilibrium - In a physical system, equilibrium refers to a state where the net force and net torque on each particle are zero, and the potential energy is at a minimum. It is a stable state where the system tends to remain unless disturbed by an external force.

Question 16:

## Which of the following is a measure of an object's resistance to rotational motion?

Click to see Hint ⬇
It is the rotational counterpart of mass in linear motion.
Inertia - Inertia is the resistance of any physical object to any change in its state of motion, including changes to its speed and direction. In rotational motion, it refers to the object's resistance to changes in its rotational state.

Question 17:

## Which of the following is the SI unit for angular displacement?

Click to see Hint ⬇
It is defined as the angle subtended at the center of a circle by an arc whose length is equal to the radius of the circle.
Radian - The radian is the standard unit of angular measure, used in many areas of mathematics and physics. It represents the angle subtended by an arc of a circle that has the same length as the circle's radius.
