What happens when weight and drag force are equal?

When drag is equal to weight, there is no net external force on the object, and the acceleration becomes zero. The object then falls at a constant velocity as described by Newton’s first law of motion. The constant velocity is called the terminal velocity.

How do you calculate drag force with weight?

The net external force is equal to the difference between the weight and the drag forces (F = W – D). The acceleration of the object then becomes a = (W – D) / m . The drag force depends on the square of the velocity. So as the body accelerates its velocity (and the drag) will increase.

Can the drag force equal the force of gravity?

The downward force of gravity remains constant regardless of the velocity at which the person is moving. However, as the person’s velocity increases, the magnitude of the drag force increases until the magnitude of the drag force is equal to the gravitational force, thus producing a net force of zero.

What happens when drag force is greater than weight?

In the hypothetical scenario where you have a constant force that’s greater than the weight pulling on the object, then the object will indeed start falling upwards. It would accelerate upward.

Is weight the same as drag?

Weight is the force of gravity. Drag is the force that acts opposite to the direction of motion. Drag is caused by friction and differences in air pressure.

Does drag force depend on mass?

Drag depends directly on the mass of the flow going past the aircraft. The drag also depends in a complex way on two other properties of the air: its viscosity and its compressibility. These factors affect the wave drag and skin friction which are described above.

What is the relationship between mass weight and gravity?

In summary, mass is a measure of how much matter an object contains, and weight is a measure of the force of gravity acting on the object. Gravity is the attraction between two objects that have mass.

What does the drag coefficient depend on?

velocity
Drag is associated with the movement of the aircraft through the air, so drag depends on the velocity of the air. Like lift, drag actually varies with the square of the relative velocity between the object and the air.

What happens when the size of the drag force equals the force of gravity?

How does weight affect drag?

The heavier the weight, the faster the speed of the object (due to gravity), which will lead to the object colliding into more air molecules per second and therefore making the magnitude of the drag force on the object slightly bigger.
