Question

You toss asmall ball vertically up in the air. how are the velocity and acceleration vectors of the ball oriented with respect to one another during the ball's flight up and down?​

Answer 1

Answer:

Acceleration of the gravity is always constant

in magnitude and direction - straight down to earth.

During the flight up, direction of the speed of

ball is upwards and acceleration - down

(deceleration). When the ball reaches the top point

of the trajectory (zero speed), it does not apply

velocity and acceleration only acts.

During the flight down the velocity and

acceleration have the same direction (acceleration),

that is, the speed of the ball increases due to the

acceleration. While falling to the ground speed of the

ball will be the same as before the throw (if we

ignore air resistance).
