Force Types of Forces Gravity, Mass and Weight Effects of Forces

What is force? Push Pull

An interaction between two masses Common symbol: F Unit: Newton, N May the Force be with you.

Types of Forces: Contact Force Pull Normal Force Friction Tension

Upthrust Drag Types of Forces: Contact Force

Replace it with your original text. Thrust Types of Forces: Contact Force

Replace it with your original text. Thrust Lift Types of Forces: Contact Force

Weight Gravitational Force Types of Forces: Non-Contact Force

Region of space around a body How can gravitational force act without contact?

Replace it with your original text. Thrust Gravitational force acts within the gravitational field

Mass versus Weight MassMass –Amount of matter in an object –unit: kilogram, kg –Does not change with location

Mass versus Weight Weight Weight Gravitational force on the object Gravitational force on the object Unit: Newton, N Unit: Newton, N Equal to mass x acceleration due to gravity Equal to mass x acceleration due to gravity W = m x g Where g = 9.81 ms -2 Changes with location Changes with location

Types of Forces: Non-Contact Force Electrical Force

Types of Forces: Non-Contact Force Magnetic Force

Weight Normal force Weight Air resistance

Weight Normal Force Drag Friction Thrust

Weight Upthrust Drag Thrust
