Albert needs to determine the force of gravity on a 250 g ball. The force of gravity on a 1000 g ball is about 10 Newtons.
Albert measures the force of gravity on the 250 g ball, and finds it to be 4 N. He does not think that this measurement is correct. What should be the force of gravity on the ball?
A.
The force of gravity on the ball should be 0 N.
B.
Albert's measurements are correct.
C.
The force of gravity on the ball should be about 10 N.
D.
The force of gravity on the ball should be about 2.5 N.
