That means that something is moving down.
Terminal velocity.
At the moment the skydiver exits the helicopter, their downward velocity is initially zero. As they fall due to gravity, their velocity will increase over time.
When the upward and downward forces on a falling object are equal, the object reaches terminal velocity. At terminal velocity, the object stops accelerating and falls at a constant speed.
The skydiver's downward velocity just before starting to fall would be zero, as they would be momentarily suspended in the air before gravity starts to accelerate them downwards.
The greatest velocity a falling object reaches is called terminal velocity. It occurs when the force of gravity pulling the object downward is balanced by the force of air resistance pushing upward. At terminal velocity, the object falls at a constant speed with no further acceleration.
Downward velocity is considered a negative. This is a true statement.

Terminal Velocity.
Yes, both are directed downward.
The greatest velocity a falling object reaches is called terminal velocity. It occurs when the force of gravity pulling the object downward is balanced by the force of air resistance pushing upward. At terminal velocity, the object falls at a constant speed with no further acceleration.
The correct answer is B: 9.8 m/s downward. In free fall near the surface of the Earth, objects accelerate at a rate of 9.8 m/s^2 downwards due to gravity. After 0.10 seconds, the object's velocity would be 9.8 m/s downward.
This means your velocity is decreasing with time, or in other words, the object is slowing down.
Yes, but only for a single instant in time. When you throw a golf ball or a rock straight up, it has the constant downward acceleration of gravity from the moment it leaves your hand, but its velocity is certainly not constant. The velocity steadily decreases until the peak of the toss, and then it switches from upward to downward velocity. At the very peak, the velocity is zero for an instant.
