Diffrent Type Of Force Flashcards
1
Q
Weight
A
Mass is fixed weight can change
W=mg
2
Q
Normal reaction -R
A
Works against gravity For example
R- perpendicular to plane upwards
3
Q
Friction
A
Works against the motion of the Object
Rough surface - friction
Smooth surface - no friction
Diffrent surfaces have diff friction
4
Q
Air resistance
A
Opposite direction of motion
Ignored if dealing with particle
5
Q
