Force and Pressure
Storyboard Tekst
- Aahana, what's wrong ? You seem to be worried.
- Oh.. I'll help you in this. I'll teach you an easy method to remember them.
- Mom, I am unable to understand force pressure.
- Thank you, Mom
- Observe the examples I show you, only then you will know what they are.
- So, let me start with FORCE. Force is a Pull or Push that affects an object in some way.
- Yes, Mom
- Notice this Aahana. While you pedal bicycle , it starts moving from stationary position. So it is changing the state of an object . Same is the case when you kick football.
- Dear, when I make dough I change the shape to make a chapati .So here shape is changed due to force.
- Yes, Mom. Now I got it.
- I will give some examples so that you can understand easily . Your school bags have broad handles/straps so as to reduce the pressure . If it is thin , you will feel more pressure on your shoulders and you will feel the pain .
- See, now I will make you understand the Pressure .Pressure is defined as the force applied on per unit area. More is the area less is the pressure and less is the area more is the pressure .
- Yes Mom. I am able to understand and relate these these two concepts.
- This says that P is directly proportional to F and Inversely proportional to A. This means if you increase the pressure applied force also will get increased
- You should also know the formula to calculate pressure P =F / A.
- Is it still confusing Aahana ?
- You're welcome, Aahana
- Thank you so much, Mom. I understood FORCE and PRESSURE properly by the examples you gave me today.
- It is better now. Mom,
- You may come to me for any of the problem that you face .
- Aahana, do you feel ok now ?
- Yes Mom, I do
