Normal Reaction Force

• Prevents objects from falling through the ground

• Acts on mass due to being in a gravitational field

• Opposes motion

• Allows flying objects to remain in the air

• Difference between forward and friction force

Friction

• Prevents objects from falling through the ground

• Acts on mass due to being in a gravitational field

• Resistance of objects when moving over another.

• Allows flying objects to remain in the air

• Difference between forward and friction force
