What causes falling objects to speed up as they fall?
Falling objects speed up due to the acceleration of gravity acting on them. As an object falls, the force of gravity pulls it downward, causing it to accelerate. This acceleration causes the object to increase in speed until it reaches terminal velocity or hits the ground.
What is meant by terminal velocity of a falling object?
Terminal velocity of a falling object is the constant speed at which the object no longer accelerates due to air resistance. At this point, the gravitational force pulling the object downwards is equal to the force of air resistance pushing against it, resulting in a net force of zero. This causes the object to fall at a constant speed.
A ball falling through the air has?
acceleration due to gravity acting on it, which causes it to increase in speed as it falls. The force of air resistance also acts on the ball, gradually slowing it down. Eventually, the ball reaches terminal velocity, where the force of gravity is equal to the force of air resistance and the ball falls at a constant speed.
Why do falling objects speed up as they fall?
Falling objects speed up due to the acceleration of gravity. As an object falls, the force of gravity causes it to accelerate towards the Earth at a rate of 9.8 m/s^2. This acceleration increases the object's speed over time.
How does gravity effect a falling object?
Gravity causes a falling object to accelerate downwards at a rate of 9.81 m/s^2 (on Earth). The force of gravity acting on the object causes it to increase in speed as it falls towards the ground.
What causes things to fall to the ground at different speed?
Gravitational force of attraction....

What is terminal velocity and what causes it?
Terminal velocity is the constant speed that an object reaches when the drag force of the air resistance is equal in magnitude and opposite in direction to the force of gravity acting on the object. This balance of forces causes the object to stop accelerating and fall at a constant speed.
What is reason for things falling down?
Objects fall down due to the force of gravity. Gravity is a fundamental force that pulls objects towards the center of the Earth. When an object is unsupported, gravity causes it to accelerate downwards until it reaches the ground.
How does drag work?
Drag force, or the force of air friction for a falling body, increases with speed. A falling object will reach a speed at which the force of air friction will be equal to and opposite the force of gravity. At that point, the object will no longer accelerate. It's speed will remain constant, and we call that speed (and direction) its terminal velocity.
What is a force that causes something to speed up?
A force that causes something to speed up is called acceleration. This force can be produced by pushes, pulls, or gravity acting on an object.
What is the name for the highest speed when falling?
The highest speed when falling is called terminal velocity. This occurs when the force of gravity pulling an object down is balanced by the force of air resistance pushing against it, resulting in a constant speed.
What is the speed limit of falling objects called?
The speed limit of falling objects is called terminal velocity. This is the constant speed that a freely falling object eventually reaches when the resistance of the medium it is falling through (like air) equals the force of gravity acting on it.
