- Directions: Write TRUE is the statement is correct but if it is false, change the underlined words with the correct answer. 1. A force is a push or pull 2. Force is a galar quantity 3. The unit of force is Newton (N) 4. In general, a body can have several forces acting on it at the same time 5. Inertial frame of reference are reference frame where Newton's First law are observable. 6. Another effect of a balanced force, equilibrium, is that a body accelerates. 7. The heavier the object, the lesser the inertia. 8. Forces acting on a body are unbalanced if the resultant force is not zero 9. In an inertial reference frame, No forces should be exerted within the frame. 10. Normal force is lateral in nature. П.
