Question

1) Object "A" has twice the weight of object "B" at a given point on the moon's surface. "A" must have twice the mass of "B".  True or False

2) The two objects above are moved to Mars. At the same place on the surface of Mars, the weight of "A" will be twice that of "B."  True or False

3) For a given object composed of a known material on a known surface, the  coefficient of kinetic friction is usually expected to be greater than the coefficient of static friction. True or False

4) A ball is dropped from an LWIT baloney. While falling, more than one force acts on it in the vertical direction. Identify the forces and select all the correct answers below.
a)Gravity
b) Normal Force
C) Tension
d)Lift
e) Friction

5) If there are only two forces on the above ball while falling and if their magnitudes are the same but their directions are opposite, then the ball's vertical velocity is constant. True or False

6) For the conditions in the question directly above, the ball is not accelerating and it is in equilibrium. True or False

7) The above ball's mass is 2.041 kg. What is the magnitude of the gravitational force acting on it?

8) If friction is neglected, what is the magnitude on the ball's acceleration in the vertical direction?(in m/s²)
