Question

An object has a constant mass. A constant force on the object produces constant a. velocity. b. acceleration. 15. c. both A and B d. none of the above A rock is thrown vertically into the air. At the very top of its trajectory the net force on it is a. its weight. b. less than its weight. 16. c. more than its weight. Which of the following is a pair of vector quantities? a. Speed Distance b. Velocity Distance 7. c. Velocity- Displacement d. SpeedDisplacement What is the resultant of two displacement vectors having the same direction? a. The resultant is the sum of the two displacements having the same direction as the original vectors. The resultant is the difference of the two displacements having the same direction as the original vectors. The resultant is the sum of the two displacements having the direction opposite to the direction of the original vectors. b. c. direction of the original vectors. :Which of the fallawino curves h

Explanation / Answer

15. (b) acceleration

if force and mass ,both are cnstant then their ration must be constant i.e. their acceleration a =F/m
