ICSE Class 8 Physics, Unit 3: Force and Pressure
From the CISCE curriculum. 4 key concepts, about 2 days of study at 20 to 30 minutes a day.
What this unit aims at
A force is a push or pull upon an object resulting from the object's interaction with another object. Turning effect of a force is more if the distance between the point of application of force and the pivot is more. It is given a special name, Moment of force. Pressure is defined as force per unit area. Solids, liquids and gases, all exert pressure. Atmosphere also exerts pressure.
Your child should be able to
- explain the turning effect of a force, with examples from daily life
- define moment of force
- express moment of force in proper units
- solve simple numerical problems based on moment of force
- define pressure
- express pressure in proper units
- solve simple numerical problems based on formula for pressure
- describe pressure exerted by a liquid
- demonstrate that liquids exert pressure
- describe pressure exerted by a gas
Key concepts in this unit
- Turning effect of force (moment of force): concept, definition and calculation Pressure:
- Definition Unit Calculation of pressure in simple cases
- Pressure exerted by liquids (Qualitative only).
- Pressure exerted by gases- Atmospheric pressure (Qualitative only).
Teach this unit at home
- A day-by-day plan from the CISCE concepts, so you know what to cover each day.
- A step-by-step script for each day, so you know what to say and ask (AI-written from the CISCE curriculum, so check it against your child's school book).
- A quiz at the end.
