   Hints to answer the give reason type questions based on pressure class 8


  1. Pressure in solids

  • Check whether the area of contact is increasing or decreasing in given situation

  • Write; Pressure is inversely proportional to area

  • Write Increase or decrease in pressure according to the given area.

  • Conclusion


  1. Pressure in liquids

  • Identify the property that matches with the given statement.

  • Check whether the pressure = force/area formula can be used.

  • Conclusion


  1. Pressure in gases

    • Check in the statement, whether the surrounding is at low air pressure or the object.

    • Write, Air flows from high pressure to low pressure

    • Write the correct flow of air taking place

    • Conclusion

FRICTION Q.1. What is force? Write few of its characteristics. Ans.1.  A push or a pull on an object is called a force.                      Force is a vector quantity (having magnitude  as well as direction).           S.I. unit of Force is N (Newton).           Force can Change the State of Motion.                   Force can Change the Shape of an Object. s          Q.2. What is friction ?      Ans.2.  The force which opposes the motion of an object on the surface of another object is called force of friction. Force of friction is a contact force. The force of friction always opposes the applied force (direction of motion).

FRICTION Q.3.  Suppose your writing desk is tilted a little. A book kept on it starts sliding down. Show the direction of frictional force acting on it. Ans.3.                                 Q.4. What is the cause of friction? Ans.4.  Friction occurs due to the interlocking of irregularities between two surfaces in motion to each other. Every object has some sort of irregularities in its surface, so when two surfaces come in contact with each other and one object moves over the another, so their irregularities get interlocked and moving object starts losing its energy in breaking the interlocking and finally it comes to rest.                                             Q.5. What are the factors on which friction depends? Ans.5.  There are two factors affecting friction: 1.      Nature of the surfaces: Friction increases with roughness and decreases with smoothness of the surfaces. On rough surfaces, there are a larger number of irregularities than the s

PRACTICE WORKSHEET (CLASS - VIII) TOPIC – FORCE AND PRESSURE 1. When a force acts on a moving object, it can make the object a) move faster b) slow down c) stop d) all of these 2. Name the type of forces involved in the following :  a) A horse pulling a cart _________________________  b) A moving boat coming to rest when rowing is stopped ___________________ c) A coin falling to the ground on slipping from hand ______________________  d) A sticker attached to steel almirah without glue _________________________ 3. Two students fought over a lunch box, both started pulling it from opposite ends but the box didn't move from its place. What will you infer about the magnitude and direction of the forces? 4. An archer shoots an arrow in the air horizontally. However, after moving some distance, the arrow falls to the ground. Name the initial force that sets the arrow in motion. Explain why the arrow ultimately falls down. Assertion / Reason :  For question numbers 5, two sta
