Modified True or False.

Read each statement carefully. Write TRUE if the statement is correct. If it is not, PROVIDE the RIGHT TERM that made the statement false. Write your answer on a separate sheet of paper.

_____1. All living things show motion whereas non- living things show motion only when force acts on them.

_____2.Galileo inferred that objects in vacuum fall with constant acceleration.

_____3. Aristotle had the idea that heavier object fall faster than lighter objects.

_____4. In Galileo's experimentation using two different weights of ball dropping in the leaning Pisa tower, he proves that heavier and lighter object fall at the same time provided that there is no air resistance. He also measures the acceleration.

_____5. Freely falling bodies undergo constant acceleration.

_____6. Motion is constantly changing.

_____7. Galileo used an inclined ramp in order to measure acceleration.

_____8. When the object, is changing position with respect to its surrounding with a given time it is called motion.

_____9. In measuring motion, point of reference is considered.

_____10. According to Aristotle, free- fall undergoes constant acceleration.

_____11. The gravity of earth surface is 9.8m/s².

_____12. A ball rolling down in an inclined plane increases its speed by different value after every second.

_____13. Aristotle believed that objects fall at a speed which is proportional to their weight.

_____14. The role of air resistance in falling heavier and lighter objects is to slow down the lighter one.

_____15. Rolling ball is an example of vertical motion.​
