Question

Four different balls with different masses (measured in grams) were dropped from the same height on Earth. Assuming no other forces acted on the balls, match each ball with the gravitational force (measured in newtons) it experienced as it fell.gravitational force = 9.8 m/s2

Answer 1

We will have the following:

1. 143 g = 0.143 kg:

`F=(0.143kg)(9.8m/s{}^2)\Rightarrow F=1.4014N`

2. 110 g = 0.110 kg:

`F=(0.110kg)(9.8m/s^2)\Rightarrow F=1.078N`

3. 410 g = 0.410 kg:

`F=(0.410kg)(9.8m/s^2)\Rightarrow F=4.018N`

4. 46 g = 0.046 kg:

`F=(0.046kg)(9.8m/s^2)\Rightarrow F=0.4508N`

From this we can see that the given weights do not correspond to any of the values of column B, since the calculations to obtain the values of column B were done using grams, instead of kg, thus those values do not correspond to the unit of force Newtons.
