Q.No.3.3: - Can the velocity of an object reverse direction when acceleration is constant? If so, give an example.

Q.No.3.3: - Can the velocity of an object reverse direction when acceleration is constant? If so, give an example.
Ans: - Yes, it is possible that the velocity of an object reverse direction when acceleration is constant. For example when we throw a body upward then the direction of acceleration will be downward while acceleration remains same.

  1. The answer above is incorrect. Gravitational acceleration is constant, and points toward the Earth's center of mass, but if this were the only force (or acceleration) acting on the body, it could only "fall". The act of moving a body against gravity requires forces moving against gravity. The NET force on the body is what's important. Missiles couldn't go "up" without an upward force.
