Describe a situation in which gravity causes a change in velocity why does a change in velocity happen?
When an object is dropped from a height, gravity causes it to accelerate towards the ground. This acceleration leads to a change in velocity as the object's speed increases. The change in velocity occurs because gravity exerts a force on the object, pulling it towards the Earth.
What else can I help you with?
What is a situation gravity causes a change in velocity and why does the change of velocity happen?
A situation where gravity causes a change in velocity is when an object is dropped from a height. As the object falls, gravity acts on it, causing it to accelerate towards the ground. The change in velocity happens because gravity exerts a constant force on the object, causing it to increase its speed over time.
Where is a situation when gravity causes a change in velocity?
One common example is when an object falls freely due to gravity. As the object accelerates towards the Earth, its velocity changes because gravity is constantly acting on it. The object's velocity increases as it falls towards the ground.
What causes falling objects to reach top velocity?
Falling objects reach top velocity due to the acceleration of gravity pulling them downwards. As the object falls, the force of gravity causes it to accelerate until air resistance (or another opposing force) balances out the acceleration, leading to a constant velocity known as terminal velocity.

Why velocity is non zero when ball dropped to the ground?
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.

How is the initial velocity zero but the acceleration is not?
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]

Describe how gravity causes stars to form galaxies?
It depends on how much gravity that causes stars to form. It depends on how big the star in the galaxies is.
Why velocity is non zero when ball dropped to the ground?
The initial velocity of a dropped ball is zero in the y (up-down) direction. After it is dropped gravity causes an acceleration, which causes the velocity to increase. F = ma, The acceleration due to gravity creates a force on the mass of the ball.
How does the unbalanced force of gravity affect the horizontal and vertical velocity of an object in projectile?
In the absence of air resistance, the force of gravity has no effect on the horizontal component of a projectile's velocity, and causes the vertical component of its velocity to increase by 9.8 meters (32.2 feet) per second downward for every second of its flight.
What causes a falling object to reach terminal velocity?
Terminal velocity occurs when the force of gravity pulling an object down is equal to the air resistance pushing up against it. At this point, the object stops accelerating and maintains a constant velocity. This happens when the drag force on the object becomes large enough to balance out the downward force of gravity.
What causes an object to reach its terminal velocity?
An object reaches its terminal velocity when the force of air resistance equals the force of gravity pulling it down. This balance of forces causes the object to stop accelerating and fall at a constant speed.
How does gravity effect a falling object?
If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
How is gravity related to terminal velocity?
Based on the 9th grade book of Physical Science... Gravity is a force that acts between two masses, and Terminal velocity is the constant velocity of a falling object when the force of air resistance equals the force of gravity. So, gravity causes objects to accelerate downward, whereas air resistance acts in the direction opposite to the motion and reduces acceleration... which ties together terminal velocity.
