As something falls from a higher building, its velocity increases due to the acceleration of gravity pulling it downward. The velocity will continue to increase until it reaches terminal velocity, which is the maximum speed at which the object can fall due to air resistance balancing the force of gravity.
What else can I help you with?
What change would most likely increase the velocity of a river?
Increasing the gradient or slope of the river bed is most likely to increase the velocity of a river. This change allows water to flow more rapidly downhill, resulting in higher velocity.
What is the function of the mass and velocity of moving object?
Momentum
Who has larger acceleration?
An object with a greater acceleration covers a larger change in velocity in a given time period compared to an object with a smaller acceleration. It is determined by the rate of change of velocity, with higher acceleration leading to a faster increase in speed.
What is viscous force directly proportional to?
Viscous force is directly proportional to the velocity gradient, which represents the change in velocity per unit distance. This means that the higher the velocity gradient, the greater the viscous force acting on the fluid.
How can one determine velocity from a position-time graph?
To determine velocity from a position-time graph, you can find the slope of the graph at a specific point. The slope represents the rate of change of position, which is the velocity at that point. A steeper slope indicates a higher velocity, while a flatter slope indicates a lower velocity.
What three ways the velocity of a car can change?
The variably of velocity can be increased or decreased by altering other factors. The removal or reduction of air resistance can result in higher velocity (if force is held constant). If force is increased velocity can also become higher. Reduction of mass and varying gear ratios can also correspond to higher velocity.
What change would most likely increase the velocity of a river?
Increasing the gradient or slope of the river bed is most likely to increase the velocity of a river. This change allows water to flow more rapidly downhill, resulting in higher velocity.
What are quantities can be determined from velocity-time diagram?
Distance from starting point Instantaneous velocity Average velocity Acceleration or deceleration Rate of change of acceleration and higher rates of change. Some of these can only be determined if the diagram is smooth or for smooth parts of the diagram.
What does the graph of distance vs time look like for something going a constant velocity?
It looks like a line steadily getting higher and higher

What resist change in velocity?
Objects with greater mass resist changes in velocity more than light objects. Additionally, objects with higher inertia or momentum also resist changes in velocity. Friction and air resistance can also act to resist changes in velocity.
How does the initial velocity change with he point of released of inclined plane?
The initial velocity of an object released from an inclined plane depends on the height from which it is released. The higher the release point, the greater the initial velocity of the object due to the larger potential energy it possesses. This initial velocity will determine the object's motion once it leaves the inclined plane.
How can one determine the velocity on a position-time graph?
To determine velocity on a position-time graph, calculate the slope of the line at a specific point. The slope represents the rate of change in position over time, which is the velocity. A steeper slope indicates a higher velocity, while a flatter slope indicates a lower velocity.
What is the velocity of an average shower head?
The velocity does not depend on ther shower head, however it does depend on the cold mains pressure, a higher pressure will result in a higher velocity, and visa versa.
