Physics - ICS Part 1 Physics Chapter 3 Short Questions Test

Question # 1

Define the following terms?
Acceleration
Uniform Acceleration
Variable Acceleration
Radical Acceleration
Linear Acceleration
Positive Acceleration
Negative Acceleration
Instantaneous Acceleration

  • Ans 1: Acceleration:The rate of change of velocity is known as acceleration.
    Mathematically, we have
    Acceleration = v/t It is a vector quantity. It SI unit m/sec2
    Dimensions of acceleration:We know that
    V= Displacement / time = m/sec= Length / Time
    V=[L T-1]
    Dimensions of acceleration:We Known that
    a = Velocity/time = m/sec . sec = m/sec-2
    a = Length/time2 a = [L T-2]
    Uniform Acceleration:A body is said to be moving with the uniform acceleration if equal change occurs in velocity in equal intervals of time.
    Variable Acceleration:A body is said to be moving with variable Acceleration if unequal change occurs in velocity in equal intervals intervals of time.
    Linear Acceleration:The acceleration which is produced due to change in magnitude of velocity is known as linear acceleration.
    Radical Acceleration:The acceleration which is produced due to change indirection of velocity is known as radical acceleration.
    Positive Acceleration:The acceleration is said to be positive if the magnitude of velocity increases with respect to time.
    Negative Acceleration:The acceleration will be magnitude of velocity decreases with respect to time.
    InstantaneousAcceleration:The acceleration of a body at any particular instant of time is known as instantaneous acceleration.

Question # 1

An object is thrown vertically upward.Discuss the sign of acceleration due to gravity, relative to velocity, while the object is in air.

  • Ans 1: When the object is thrown vertically upward, it will move against the direction of gravity. The sign of acceleration due to gravity relative to velocity will be taken as negative. When the object is moving downward, the sign of acceleration due to gravity will be positive.
