Question

An object is thrown straight up into the air and feels no air resistance. How can the object have an acceleration when it has stopped moving at its highest point?

Answer 1

Step-by-step explanation:

All objects on Earth are subjected to a constant gravitational acceleration g = 9.8m/s2, wherever they are on the surface of Earth and whatever their speed is. So if an object is being thrown to its highest point and stopped moving at that instant, that means the velocity at that instant is 0, not the acceleration. The acceleration is still g = 9.8m/s2
