Force
What is force?
Push/pull
Capacity to do work
Cause physical change
Types of force
Magnetic force
Push/pull
2 magnets
Magnetic and nonmagnetic
Frictional force
Redece
Lubricants
Oil
Water
Ball bearings
Increase
Rougher materials
Rubber
Softer materials
Rug
Increase weight of two surfaces
Gravitational force
Weight
Amount pf gravitational
force acting on the object
Mass x gravitational force
NOT mass
Amount of matter in the object
How to calculate force?
Force = mass x acceleration
Measured in Newton (N)
1 N = 1 pascal x sq metre
Pressure
How to calculate pressure?
Pressure = force/area
Measured in pascal (pa)
1 pa = 1 Newton/sq metre
What is pressure?
Force per unit area applied in a direction
perpendicular to the surface of an object
Force acting on an area (per
unit area)
Increasing pressure
Decrease surface area
Decreasing pressure
Increase surface area
