Force and Pressure - Coggle Diagram
Force and Pressure
Pressure
Force applied on a surface per unit area
Formula: P = F/A
SI Unit: Pascal (Pa); Pa=N/m^2
Area is inversely propotional to pressure
Force is directly proportional to pressure
Always from High pressure to low pressure
Liquid Pressure
Force exerted by a liquid per unit area
Pressure is equal laterally
Increases with depth
Measured by a manometer
Atmospheric pressure
Force exerted by the atmosphere per unit area
Inversely proportional to altitude
Measured by a barometer
A push or pull that affects an object in some way is called force
Effects of force
Can cause an object to start moving
Can cause an object to stop moving
Change the direction of motion
Change shape of object
Change the speed of an object
Types of Force
Contact force
Muscular force
Friction
Mechanical force
Non-contact force
Gravity
Magnetic force
Electrostatic force
