A) Acceleration
B) Luck of friction between paper and glass
C) Inertia
D) Newton's third law of motion
Correct Answer: C
Solution :
[c] Inertia was best explained by Sir Isaac Newton in his first law of motion. Basically, the law states that an object at rest stays at rest and an object continues its state of motion until an external force acts on it. Here are some examples: 1. One's body movement to the side when a car makes a sharp turn. 2. If pulled quickly, a tablecloth can be removed from underneath of dishes. The dishes have the tendency to remain still as long as the friction from the movement of the tablecloth is not too great. 3. If you jump from a car of bus that is moving, your body is still moving in the direction of the vehicle. When your feet hit the ground, the grounds act on your feet and they stop moving. You will fall because the upper part of your body didn't stop and you will fall in the direction you were moving.
