If two objects with the same shape are dropped from the same height, which object till hit the ground first? Object A has a mass of 50g and object B has a mass of 50g.

• Object A

• Object B

• Both will hit at the same time.

• It depends on the shape of the object.

In class, we are investigating Newton's 2nd Law of motion. We measure the force applied to move a textbook across the desk. The textbook has a mass of 2kg and the force measured is 4 N. The textbook moved across the table with a constant acceleration. Which statement best describes why this happened?

• The force measured was the force of friction and without friction the textbook accelerates at 2 m/s2

• The force measured was the net force and without this force the textbook would have moved faster.

• The force is the force of gravity and without this force the textbook would not move.

• The force is the net force to the right, which causes the textbook to move at a constant acceleration.
