23 You might have noticed that a feather falls slowly toward the ground, while a ball falls rapidly.
Which statement correctly explains the motion of these objects?
A. The ball does not experience fluid friction as it falls
B. Gravity is the only force acting on the feather and the ball
C. The feather experiences more fluid friction than the ball
D. The acceleration of the ball and feather are the same

The graph describes the motion of an object. the object moves with from a to b. it from b to c. it moves with from c to d.

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
