A) 4 m/s2 B) 3 m/s2 C) 2 m/s2 D) 1 m/s2
______6. An object falling near the surface of the earth has a constant acceleration of 9.8 m/s2. What does this
mean?

______7. If an object falls with constant acceleration, what must the velocity of the object be?
A) be constant also C) continually change by the same amount each second
B) continually decrease D) continually change by varying amounts depending on its speed
______8. A ball is thrown upwards and caught when it comes back down. In the presence of air resistance, what
is the speed with which it is caught?
A. more than the speed it had when thrown upwards
B. less than the speed it had when thrown upwards
C. the same as the speed it had when thrown upwards
D. less or more than the speed it had when thrown upwards depending on how you catch it
