Challenge A.
Write true if the statement is correct. If false, change the italicized word in the statement to make it true.
1.A car that decelerates speeds up. 2.Motion implies a change in position.
3.Speed is expressed in mass per unit time.
4.Motion is a result of the application of force.
5.An unbalanced force gives a zero net force.
6.Velocity is acceleration in a particular direction.
7.Acceleration is dependent on force and distance.
8.A mango fruit hanging on a tree exerts a downward force due to gravity.
9. In a directly proportional relation, when one factor increases, the other decreases.
10. Newton's second law of motion states that for every action, there is always an equal and opposite reaction.
-Pag false po pa explain na lang ung totong sagot o explanation.
Please lang.

Answer:
Challenge A:
1. False. *Decelerates* should be changed to *accelerates*. A car that decelerates slows down.
2. True. Motion implies a change in position.
3. False. *Speed* should be changed to *mass*. Mass is expressed in mass per unit time.
4. False. *Motion* should be changed to *force*. Motion is a result of the application of force.
5. False. *Unbalanced* should be changed to *balanced*. A balanced force gives a zero net force.
6. True. Velocity is acceleration in a particular direction.
7. False. *Distance* should be changed to *force*. Acceleration is dependent on force and mass (not distance).
8. True. A mango fruit hanging on a tree exerts a downward force due to gravity.
9. False. *Decreases* should be changed to *increases*. In a directly proportional relation, when one factor increases, the other also increases.
10. False. *Always* should be removed. Newton's second law of motion states that for every action, there is an equal and opposite reaction.
