Chapter 3 Online Short Questions Preparation

Every physical process involves the movement of some sort. Due to its importance in the physical world around us, it is logical that we should give due attention to the study of motion. We are already aware of the fact that motion and rest are relative. Here in this chapter we shall learn other related topics in some more details.

At the end of this first-year physics online chapter 3 test session students will be able to:

Understand and define displacement from its definition and illustration.

Understand velocity, average velocity, and instantaneous velocity

Understand acceleration, average, acceleration, and instantaneous velocity

Describing the significance of the area under the velocity-time graph

Recall Newton’s law of motion

Describe Newton’s second law of motion as the rate of change of momentum

Exams are near and want the preparation to be accurate and according to the standards, then download the past papers and guess papers from our website. Lacking behind in lectures and understanding of topics or chapters then download the notes or take the online lectures. Exams are near and waiting for the date sheet no worries download it from the date sheet section. Exams are over and waiting for the result, and then the wait may over as you can check the result also.

Question # 1

Define Collision ? Discuss the type of collision?Give example in each case?

Ans 1: Collision:When two or more than two bodies come so closer to each other that there exists some type of interaction between them in the presence or absence of external forces then such type of interaction is known as collision.
Type of Collision:There are two type of collision, which are given below.
Elastic Collision:The Collision in which the momentum and kinetic energy both are conserved is known as elastic collision.
Examples:
1. collision of steel balls,
2. Collision of atoms,
3. Collision of molecules.
Inelastic Collision:The Collision in which the momentum is conserved but K.E is not conserved, is known as Inelastic collision. "
In such type of collision, same type of the K.E is converted into internal energy, sound energy and the work needed to permanently deform the object involed, such as cars ina car crash.
Example:
1. Collision between two vehicles
2. Collision between two mud balls

Question # 1

Define inertial and non-inertial frame of references.

Ans 1: Inertial Frame of References: The frame of reference in which Newton's first law holds is called inertial frame of reference. It is not an accelerated frame of reference.e.g,, Earth is approximately an inertial frame of reference.
Non-Inertial Frame of Reference: The frame of reference in which Newton's first law does not hold true is called non-inertial frame of reference.It is an accelerated frame of reference e.g., Space ship etc.

Question # 1

What is Ballistic Flight and Ballistic Missile?

Ans 1: The flight in which projects is given an initial and is then allowed to move freely due to inertia and under the action of gravity is called ballistic flight.
Ballistic missile is an unpowered and unguided missile.The flight of Ballistic missile is Ballistic flight.

Question # 1

Motion with constant velocity is a special case of motion with constant acceleration.Is this statement true?

Ans 1: Yes, this statement is true. When a body moves with constant velocity in the straight line, its acceleration is zero.Hence,The acceleration of the body will always remain constant during such motion.As the zero is a constant quantity, therefore this is a special case of motion.

Question # 6

Discuss the condition of equilibrium ?

Ans 1:
Newtons 1st Law of motion: This Law states that "A body at rest will remain at rest and a body in motion will continue its motion with uniform velocity unless it is acted upon by some unbalanced external force
If F = 0 Then a = 0
Explanation: The Ist law of motion is also known as law of inertia. The inertia is the property of a body which opposes any change in its state of motion or rest. Actually, when some force is applied on a body for changing its state of rest or uniform motion, then the body will affer resistance against this change. In the word, We can say that all the bodies try to maintain its state of rest or continue its uniform motion due to inertia. That is the why the newtons Ist law is also known as law of inertia.
Examples:When we give a jerk to the branch of a tree, then the fruit falls down. It is because, when we give a jerk, the branch of the tree comes into motion suddenly.
When a bus starts motion suddenly, the passengers experience a push in the back ward direction It is because, when the bus starts motion suddenly, the lower parts of the passenger in contact with the seats also come into motion. while the upper parts of the passengers are at remain at the rest In this attempt, they falls in the back words directions
Newton's 2nd Law of motion:
Statements: This law states that, "when a force is applied on a body, then acceleration is produced in the body in the direction of applied force and inversely proportional to the mass of the body.
Explanation: The Ist Law of motion gives us the quantitative measurements of force, While the 2nd law of motion gives us the quantitative measurements of forces. now if the direction of motion of the body and direction of motion of the body and direction of forces are the same, then its velocity and acceleration increases. If the direction of motion of the body and direction of force are opposite in direction of force are opposite in direction, then the velocity and acceleration of the body will decreases gradually and finally become zero and the body will come to rest
Example of newtons 2nd law of motion:
When a body falls on a solid floor from the top of a building, the body experience or feel great pain. It is because, when the body falls on the floor, its acceleration become zero suddenly and the body faces huge force for very short period of time
Newton,s 3rd Law of motion:
This Law states that for every action, there is always a reaction. These forces are equal in magnitude but opposite in direction.
Explanation: This law tells us that no body can experience a force from its surrounding, until this body exerts any force on its surrounding It means That forces are exerted in pairs.
