a) Linear momentum
momentum = mass × velocity
Dimension of mass = [M¹]
Dimension of Velocity
= distance / time
= [L ¹] /[ T ¹]
= [L ¹ T ^-1]
momentum = [M¹] × [L ¹T ^-1]
momentum= [L ¹ M ¹ T ^-1]
b ) Density
Density = mass / volume
Dimension of mass = [M¹]
Dimension of volume = [ L³]
Density = [M¹] / [ L³]
Density = [ L ^-3 M ¹ ]
c ) Moment of force
Moment of force = force × distance
Force = m a
Dimension of mass = [M¹]
Dimension of acceleration
= velocity / time
= [L ¹T ^-1] /[ T ¹]
= [L ¹ T ^-2]
Dimension of Force
= [L ¹ M¹ T ^-2]
Dimension of distance = [ L¹]
Moment of force = [L ¹ M¹ T ^-2] [ L¹]
Moment of force = [L ² M¹ T ^-2]
d) Power
Power = work / time
work = force × displacement
work =[L ¹ M¹ T ^-2] × [L¹]
work = [L ² M¹ T ^-2]
Power
= [L ² M¹ T ^-2] / [T ¹]
= [L ² M¹ T ^-3]
power = [L ² M¹ T ^-3]
e) impulse
impulse= force×time
Dimension of Force
= [L ¹ M¹ T ^-2]
impulse
= [L ¹ M¹ T ^-2] ×[T¹]
= [L ¹ M¹ T ^-1]
