Grade 10 Problem Solving Strategies CCSS: HSN-Q.A.1
Fg=G m1 m2r,
where Fg is the force, measured in Newtons; G is the gravitational constant, measured in N⋅m2/kg2; m1,m2 are the masses of the two objects measured in kilograms; and r is the distance between the objects, measured in meters. Using dimensional analysis, is his formula correct? Why or why not?
- Yes, since N⋅mkg2×kg1×kg1×1m=N.
- No, since N⋅m2kg2×kg1×kg1×1m=N⋅m.
- No, since N⋅m2kg2×1kg×1kg×m1=N⋅m3kg4.
- No, since N⋅m2kg2×kg1×kg1×m1=N⋅m3.
