What is true about an object falling toward Earth?
Earth pulls on the object, and the object pulls on Earth
Why does the shape of an object falling affects the time that it takes to hit the ground?
It's all about the air resistance that the object receives as it falls in an atmosphere. The air has to move around the object as it falls, if it's allowed to move smoothly aroundyam object by the objects shape then the force of the air resistance is lower. This allows the object to fall faster.
Why must a horizontally moving projectile have a large speed to become an earth's satellite?
At lower speed, the object will fall back on the ground. Since, earth is curved, if the object has enought speed, the object can try to fall beyond the curvature of the earth. Thus, it will not hit ground at all. The speed to achieve it is around 8 km/s. If the object is faster than 11.4 km/s then the object will never return. It is called escape velocity.
What force opposes gravity and slows down an object falling through the air?
drag force (frictional force exerted by air) or air reststance
How far does an object fall in one second?
Although it does not allow for factors such as air resistence, perhaps it's the formulas = (iVt) + ( (1/2)at2)where s is Distance, iV is initial velocity, t is time (t2 is time squared) and a is acceleration.Taking 0 as the initial velocity, 1 second as the change in time, 9.8 m/s as the acceleration (as it is near the earth's surface):s = ( 0(1) ) + ( (1/2)(9.8)(12) )s = 4.9The object will fall by 4.9 metres.
In free fall when the air resistance is equal to the weight of the falling object we say that the object has reached velocity?
In free fall, when the air resistance is equal to the weight of the falling object, we say that the object has reached ________ velocity.
What is the acceleration of falling object that has reached its terminal velocity?
Zero, by definition.
When a falling object has reached its teminal velocity its accleration?
When the velocity stops changing, then, by definition, the acceleration is zero.
In free fall when the air resistance is equal to the weight of the falling object we say that the object has reached velocity.?
That is called terminal velocity.That is called terminal velocity.That is called terminal velocity.That is called terminal velocity.
When a falling object stops accelerating it has reached?
In that case, it is said to have achieved terminal velocity.
When a falling object had stopped accelerating it has reached its?
"Terminal Velocity". Usually about 125 mph.
When you drag force on an object falling through the air equals the force of gravity the object has reached what?

What two-word term is the top speed reached by a free-falling object?
terminal velocity
What is the maximum velocity reached by a falling object that occurs when the resistance of the medium is equal to force due to gravity?
Its called terminal velocity
What is the maximum velocity reached by a falling object that occurs when the resistance of the medium is equal to the force due to gravity?
Its called terminal velocity
What is The greatest velocity a falling object?
the greatest velocity a falling object reaches is terminal velocity
