The acceleration of free fall on the Moon is 1.6 m s⁻². The Moon has no atmosphere. An astronaut standing on the surface of the Moon drops a feather. Which graph shows the variation with time of the speed of the feather during the first second of its fall?

1. AGraph A: straight line from origin (0,0) to (1, 1.6)
2. BGraph B: curve starting at origin with increasing gradient, reaching (1, 1.6)
3. CGraph C: curve starting at origin with decreasing gradient, reaching (1, 1.6)
4. DGraph D: horizontal line at speed 1.6 from time 0 to 1
