Question
T or F and why? 1. Velocity of an object is zero at the same instant theacceleration 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. T or F and why? 1.

1. Velocity of anobject is zero at the same instant the acceleration iszero FALSE(motion of a object connected to the spring, when schetch maximum,velocity=0, but acceleration 0) 2 If an objectis not accelerating, there are no forces acting on it.FALSE ; net the forces =0,may have force acting 3. It ispossible for a particle moving at constant speed to have constantacceleration TRUE=> uniform circular motion, having centripetal acc. 4. You place aphysics book on a table. According to Newton's third law, theupward force of the table on the book is equal in magnitude andoppostie in direction to downward force of gravity on thebook.Related Questions
