Question

Aball is thrown straight up in the air as the ball rises does itz velocity increase decrease or remain the same? does its accelaration increase decrease or remain the same?

Answer 1

Acceleration of a projectile is a constant due to gravity. At the highest point, velocity equals zero.
If we neglect air resistance, the only force acting on the ball after it's released is gravity, which is a constant downward force. So, as the ball is travelling upward the velocity decreases since the force acts opposite to its direction of motion. The acceleration remains constant as the force and mass are constant.
