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
When a stone and metalblock having same weight is thrown from a plane which will reach first?
They both will fall down at equal speed and will land equally. Test it: Drop a pencil and a rock from your house. They will fall equally. That would happen in a vacuum, however in our atmosphere falling objects encounter resistance from the air. Each object, depending upon shape and form will reach a terminal velocity. Objects that are more aerodynamic (smooth and of regular shape) will fall faster than rough and irregularly shaped objects of the same mass (weight.)
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.
The largest velocity reached by a falling object is its what?
The largest velocity reached by a falling object is its terminal velocity. Terminal velocity is the constant maximum velocity reached by an object when the drag force is equal in magnitude and opposite in direction to the gravitational force acting on the object.
What is the acceleration of falling object that has reached its terminal velocity?
Zero, by definition.
When a falling object has reached terminal velocity it continues to gain what?
When a falling object has reached terminal velocity, it no longer accelerates due to air resistance matching the force of gravity. At this point, the object continues to fall at a constant speed without gaining any additional velocity.
When a falling object had stopped accelerating it has reached its?
When a falling object has stopped accelerating, it has reached its terminal velocity. At this point, the force of air resistance acting on the object is equal to the force of gravity pulling it downward, resulting in a balanced force and a constant velocity.
The maximum velocity reached by a falling object that occurs when the resistance of the medium is equal to the force due to gravity?
The maximum velocity reached by a falling object when air resistance is equal to gravitational force is called terminal velocity. At this point, the net force on the object is zero, resulting in constant velocity. The object will not accelerate further due to the balancing forces.
When a falling object stops accelerating it has reached?
In that case, it is said to have achieved terminal velocity.
Is there a maximum velocity to a falling object?
Yes, there is a maximum velocity for a falling object, known as terminal velocity. Terminal velocity is reached when the force of air resistance on the falling object is equal to the force of gravity acting on it, resulting in a constant velocity. The terminal velocity varies depending on factors like the object's size, shape, and weight.
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?
The maximum velocity reached by a falling object when the resistance of the medium is equal to the force due to gravity is called terminal velocity. At terminal velocity, the object no longer accelerates and reaches a constant speed as the drag force balances out the force of gravity acting on the object.
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 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
