The weight of a 1.0 kilogram object on Earth is about:
A1.0 newtons
B98 newtons
C0.98 newtons
D9.8 newtons
Answer & Solution
Correct answer: D. 9.8 newtons
1. Weight equals mass times the acceleration due to gravity.
2. The magnitude of the acceleration of an object due to gravity near Earth is about 9.8 metres per second squared.
3. Multiplying 1.0 kilogram by that value gives the weight.
4. On Earth, the weight of a 1.0 kilogram object is 9.8 newtons.
5. Confusing mass with weight is the standard error here: the mass is 1.0 kilogram either way.
