## 2.1 Rest and Motion

- What is rest?
- What is motion?
- What is a position?
- What is a reference point?
- What do you understand by reference frame?
- All the rests and motion of the universe are relative, no motion is absolute, no absolute rest - explain.

##
2.2 Different Types of Motion

- What is linear motion?
- What is circular motion?
- What is translational motion?
- What is periodic motion?
- What is oscillatory motion?
- What is simple harmonic motion?
- Explain all oscillatory motions are periodic motions but all periodic motions are not oscillatory motions.

##
2.3 Scalar and Vector Quantities

- What is quantity?
- What is the normal body temperature?
- What is a scalar quantity?
- What is a vector quantity?
- Write the difference between scalar quantities and vector quantities.
- Work is a scalar quantity - explain.
- Explain the intensity of electricity as a vector quantity.

##
2.4 Distance and Displacement

- What is distance?
- What is displacement?
- The movement does not depend on the direction of the object - explain.
- What do you mean by the movement of an object is 60 m southward.

##
2.5 Speed and Velocity

- What is speed?
- What is the unit of speed?
- What is the dimension of speed?
- What is average speed?
- What is instantaneous speed?
- What do you understand by the speed of a car is 45 km/h?
- What is velocity?
- What is the unit of velocity?
- What is the dimension of velocity?
- What is average velocity?
- What is uniform velocity?
- What is unequal velocity?
- When can the velocity of an object be zero?
- Write the difference between speed and velocity.

##
2.6 Acceleration and Deceleration or Retardation

- What is acceleration?
- What is the unit of acceleration?
- What is the dimension of acceleration?
- What is uniform acceleration?
- What is unequal acceleration?
- Acceleration due to gravity is called uniform acceleration - explain.
- What is deceleration or retardation?
- Gravitational acceleration is called uniform acceleration - explain.

##
