Physics - ICS Part 1 Physics Chapter 3 Short Questions Test

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

Define Force? Define its SI unit ?

Ans 1: A Force is an agent which stops a moving body try to stop a moving body (or) which moves a stationary body (or) try to move stationary The Product of mass and accelerations known as force
F = ma
Unit of force:
F= ma = kg m/sec²So the unit of force is Newton, Which is define as,
Force is said to be 1 newton ,if it moves a body of mass 1 kg with acceleration of 1m/sec²,

Question # 1

What is the difference between uniform and variable velocity?

Ans 1: Uniform Velocity: A body is said to have a uniform velocity if it covers equal displacement in equal intervals of time.

Variable Velocity: A body is said to have a variable velocity if it covers unequal displacements in equal intervals of time.

Question # 9

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.
