presentation on pressure and force and its usage

force and pressure

1. JYOTIBA FULE COLLEGE OF EDUCATION WADI, NAGPUR   Presentation on Force and pressure       Guided by Dr. Deshmukh ma’am Presented By Disha pralhad ankar B. ed. 2 nd sem

2. Force And Pressure PUSH

3. Force A Push or a Pull acting on a body is called Force. Scaler Force Vector Force Forces that tells the magnitude is known as Skiller Force. Forces that tells the magnitude as well as Direction is known as Vector Force. Pull Push

4. Effects of Forces Force can Change the State of Motion (a moving object is known in the state of motion) Force Can Change the Size of Motion Force can change the shape of Motion

5. Types of Forces

6. Types of Force Contact force:- Force that comes into action before interaction between objects is called Contact Force. Example- Non-contact force:- Force due to without interaction between two objects is called non-contact force. Example-

7. Force acting per unit area is known as pressure. SI unit is Pascal. the pressure exerted by an object depends upon its surface area. If the surface is small, the amount of pressure applied is large, and vice-versa. Pressure

8. Force Area Pressure

9. Pressure Example-

10. The pressure exerted by liquids and gases A manometer is a device used to measure the pressure exerted by a liquid characteristics of liquid pressure- 1. pressure exerted by a liquid increases wi6th depth. 2. liquids exert pressure on walls of the container. 3. liquids exert pressure on all direction at all points. pressure exerted by gases- the force exerted by atmosphere per unit area of the surface of the earth is called atmospheric pressure 1. atmospheric pressure decrease with an increased in the altitude instrument used to measure atmospheric pressure is called barometer.

11. Atmospheric Pressure Atmospheric pressure also known as barometric pressure. the pressure exerted by the weight of the atmosphere. Which at sea level has a mean value of 101,325 pascals. pressure within the atmosphere of Earth.
