What is terminal velocity value?

What is Terminal Velocity Value?

Terminal velocity is the maximum velocity reached by a falling object when the resistance force due to the medium it moves through (such as air or water) equals the gravitational force pulling it downward. At this point, the object stops accelerating and continues falling with a constant velocity.

What factors affect terminal velocity?

Terminal velocity is influenced by several factors including the shape, size, and weight of the object, as well as the density and viscosity of the medium it falls through.

How is terminal velocity calculated?

Terminal velocity can be calculated using the formula: v = (2mg/ρAC)^(1/2), where v is the terminal velocity, m is the mass of the object, g is the acceleration due to gravity, ρ is the density of the medium, A is the cross-sectional area of the object, and C is the drag coefficient.

What happens if the object is more streamlined?

If the object has a streamlined shape, it experiences less air resistance and therefore reaches a higher terminal velocity. For example, a skydiver in a spread-eagle position will reach a lower terminal velocity compared to when they adopt a head-first dive position.

Does terminal velocity depend on the mass of the object?

Yes, the terminal velocity of an object depends on its mass. Heavier objects require more force to accelerate and experience greater resistance, resulting in a higher terminal velocity compared to lighter objects.

Can terminal velocity be achieved in a vacuum?

No, terminal velocity can only be reached when there is a medium (such as air or water) for the object to fall through. In a vacuum, without any resistance, objects will continue to accelerate indefinitely.

Can terminal velocity be exceeded?

Terminal velocity is the maximum velocity an object can reach during freefall. However, if an external force, such as a propeller, pushes the object downwards, it can exceed its terminal velocity.

Can an object have different terminal velocities in different mediums?

Yes, the terminal velocity of an object can vary depending on the medium it falls through. For example, a skydiver will experience a different terminal velocity when falling through air compared to falling through water.

At what point does terminal velocity occur?

Terminal velocity occurs when the net force acting on the object becomes zero, meaning there is no further acceleration. It is the point at which the object reaches a constant speed, continuing to fall without any change in velocity.

What happens if an object falls below its terminal velocity?

If an object falls below its terminal velocity, it will experience a net downward force and will continue to accelerate until it reaches its terminal velocity.

What happens if an object falls above its terminal velocity?

When an object falls above its terminal velocity, the resistance force from the medium it moves through exceeds the gravitational force, leading to deceleration. The object might eventually reach a new, lower terminal velocity.

Is terminal velocity the same for all objects?

No, different objects have different terminal velocities depending on their shape, size, mass, and other physical properties. For example, a feather and a rock will have significantly different terminal velocities due to their differences in mass and surface area.

Can an object reach terminal velocity when moving upwards?

No, terminal velocity is only achieved when an object falls towards the Earth (or any other celestial body) due to the force of gravity. When moving upwards, the gravitational force opposes the object’s motion, preventing it from reaching terminal velocity.
