Modified True or False Directions: Write TRUE if the statement is correct, otherwise change the underlined word to make it correct. 1. Dynamics is concerned with describing the movements of objects. 2. The kinematic equations of motion are valid for objects with constant acceleration only. 3. A body moving with constant acceleration has its speed changing by a fixed amount. 4. An object moving in the +x direction experiences an acceleration of +2.0 m/s2. This means the object travels 2.0 m in every second. 5. Freefall is an example of motion in two dimensions. 6. Ball A is dropped from the top of a building. One second later, ball B is dropped from the same building. Neglect air resistance. As time passes, the change in their speeds remains constant 7. At the surface of the Earth where air friction is negligible, all objects regardless of their masses will have the same speed 8. For an object thrown verticaly upward, the acceleration changes and becomes zero at the highest point. 9. The time it takes for an object is thrown vertically up to reach the highest point is equal to the time taken by the object to return back from the point where it is released. 10. The acceleration due to gravity varies slightly in the different areas on Earth due to latitude and altitude.
