What else can I help you with?
Velocity at which a falling object travels when the force of air resistance exactly matches the downward force of gravity is called?
Terminal velocity.
When the skydiver steps out of the helicopter someone who's watching starts a stopwatch. So the time is zero as the skydiver steps out of the plane. What is the skydiver's downward velocity at that?
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.
What is the skydive's downward velocity at thatinstant just before starting to fall?
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.
When the upward and downward forces on a falling object are equal the object reaches?
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.
What is the greatest velocity a fallingobject reaches?
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. true or false?
True. In the context of physics, downward velocity is typically assigned a negative direction because it is opposite to the positive direction conventionally chosen as the upward direction.
What is velocity at which a falling object travels when the force of air resistence matches exactly the downward force of gravity?
terminal velocity

When the upward and downward forces on a falling object or changes its direction is called an?
Terminal Velocity.
Are the directions of the velocity and acceleration of a falling body the same?
Yes, both are directed downward.
What is the greatest velocity a fallingobject reaches?
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.
What is the velocity of an object that has been in free fall for 0.10 s A 0.98 m s downward B 9.8 m s downward C-9.8 m s downward D 98 m s downward?
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.
What does a downward sloping diagonal line mean in a velocity vs time graph?
This means your velocity is decreasing with time, or in other words, the object is slowing down.
Is it possible for a body with zero velocity to have non-zero acceleration?
Yes, it is possible for a body with zero velocity to have non-zero acceleration. Acceleration is the rate of change of velocity, so a body can have an acceleration if its velocity is changing, even if it starts from rest.
