True or False and why?
1. Velocity of an object is zero at the same instant the acceleration is zero
2 If an object is not accelerating, there are no forcesacting on it.
3. It is possible for a particle moving at constantspeed to have constant acceleration
4. You place a physics book on a table. Accordingto Newton's third law, the upward force of the table on the book isequal in magnitude and oppostie in direction to downward force ofgravity on the book.
