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 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

    Can the velocity of an object reverse the direction when acceleration is constant? If so, given an example.

    • Ans 1: Yes, the velocity of a body can reverse its direction with constant acceleration For example, when a body is thrown vertically upward under the action of gravity, the velocity of the object will go on decreasing because force of gravity is acting downward.
      When the object reaches the maximum height , its velocity becomes zero, and then the object reverses its direction of motion and start moving vertically downward.During the whole process, the magnitude of the acceleration due to gravity remains constant.

    Question # 1

    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.

    Question # 1

    Define the following terms?
    Velocity,
    Uniform Velocity,
    Variable Velocity,
    Average Velocity.
    Instantaneous Velocity.

    • Ans 1: Velocity:The distance between covered by a body in one second along a particular direction is known as velocity.
      V = S/t velocity is a vector quantity. its standard unit is "m/sec
      Uniform Velocity:A body is said to be moving with uniform velocity, if it covers equal displacement in equal intervals of time .
      Variable Velocity:A body is said to be moving with variable velocity, if it covers unequal displacement in equal intervals of time.
      Average Velocity:The average velocity can be obtained by dividing total displacement by total time taken.
      Average velocity = Total Displacement /Total time taken
      V = S/T
      Instantaneous Velocity:The velocity of a body at any particular instant of time is known as instantaneous velocity.
