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.

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

What is the effect on the speed of a fighter plane chasing another when it opens the fire? What happens to the speed of purdued plane when it returns the fire?

  • Ans 1: When the fighter plane opens fire, its momentum will be in back direction due to reaction force in backwards direction and therefore its speed will decrease.
    When the pursued plane opens fire in the backward direction, the momentum will act on the plane in forward direction due to reaction and therefore its speed will increase.

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
