A body is then vertically upwards from the surface of the earth. What is the direction of its velocity and acceleration in its way up?

Open in App

Solution

Its velocity will be towards up direction. But the stone is moving against the gravitational acceleration g . Therefore g will work on the object and will reduce the velocity
So acceleration will be downward.

In a detailed manner the directions can be stated as,

While it is being thrown.
the acceleration is upwards
the speed is upwards

After you’ve released it, but before it starts to fall.
the acceleration is downwards
the speed is upwards

At the moment before it starts to fall.
the acceleration is downwards
the speed is zero (no direction for zero)

After it started to fall down.
the acceleration is downwards
the speed is downwards
