Question

How do I convert the mass of an object into force without knowing the acceleration due to gravity?

I have to find the force for three objects on springs. One weighs .05kg, one ways .10kg and the last one ways .25kg.

I know you find the force with this formula :F=mag, but I'm unsure how to get the acceleration due to gravity.

Thanks!

Answer 1

This question is not clear. Can you post the exact question you have to answer?

Answer 2

I have this data:
Trial Mass (kg) Stretched Spring (m) Highest Point (m) Lowest Point (m)
1 0.05 kg 0.32 m 0.59 m 0.51 m
2 0.10 kg 0.36 m 0.58 m 0.41 m
3 0.25 kg 0.49 m 0.53 m 0.15 m

Answer 3

And I need to fill in this data:
Trial Force (N) Spring Constant (k) PE (elastic) at highest point PE (elastic) at lowest point
1
2
3

for the same trials

Answer 4

acceleration due to gravity is always taken as 9.8 m/s^2 :P

Answer 5

Use formula -
Trial force (in N) = Mass (in kg) * g (=9.8 m/s^2)

I am not sure what does highest point and lowest point refers to..
