How is the resistance when pulling a boat in water depending on the speed of the boat?
The force of drag on any object in a fluid is given by D = 1/2 CpAV2 where C is the drag coefficient, p (which is actually the greek letter rho) is the density of the fluid, A is the effective cross sectional area(A fancy way to say the face of the object) and V is the velocity of the object. D is in Newtons. Hope this helps whoever asked. --An AP Physics Student Bored in Study Hall

What is terminal velosity?
Terminal velocity is the constant speed that a freely falling object reaches when the drag force (air resistance) equals the force of gravity pulling it downwards. At this point, the object no longer accelerates and falls at a constant speed. Terminal velocity varies depending on the object's size, mass, and shape, as well as the medium through which it is falling (such as air or water).
How does water or air resistance against an object increase speed?
It doesn't increase speed. The word resistance means to resist. In other words it decreases speed.
Air and water resistance?
Air resistance is that resistance when substance moves in air and it expresses a opposite force on it. However, water restinace is water when a substance moves thorugh water and it expresses and oppoisite force.
Does water resistance speed up moving objects?
Water resistance acts as a drag force on moving objects, slowing them down rather than speeding them up. The resistance depends on factors such as the shape and speed of the object moving through water.
What happens if water hits terminal velocity?
If water were to reach terminal velocity, it would fall at a constant speed due to the balance between gravity pulling it down and air resistance pushing it up. This means that the water would no longer accelerate and would continue to fall at that maximum speed until it reaches the ground or another surface.
Do objects travel the same speed in all mediums?
No, objects do not travel at the same speed in all mediums. The speed of an object can vary depending on the medium it is traveling through, such as air, water, or more dense materials. This variation is due to factors such as resistance, density, and the material's composition.
Once an object is in motion what is an example of a force that will slow it down?
Friction. Air Resistance or Water Resistance, depending on where you are and what your doing.
What is water resistance as a frictional force?
Water resistance is the frictional force that opposes the motion of an object through water. It occurs due to the interaction between the object's surface and the water molecules, slowing down its movement. Water resistance increases with speed and the surface area of the object in contact with the water.
Which causes an object to change its speed?
An object changes its speed when an external force is applied to it. This force can either increase or decrease the object's speed depending on its direction and magnitude. Factors such as friction, air resistance, and gravity can also influence the object's change in speed.
What is the force of water resistance?
The force of water resistance is the opposing force that water exerts on an object moving through it, slowing down its motion. It is influenced by the object's speed, shape, and surface area in contact with the water.
What is the explanation of how the water resistance force works?
Water resistance force, also known as drag, is the force that opposes the motion of an object moving through water. It is caused by the friction between the water and the surface of the object. The magnitude of the water resistance force depends on the speed of the object, its shape, and the properties of the water.
What is the terminal velocity of water and how does it impact the motion of objects falling through it?
The terminal velocity of water is the maximum speed at which an object can fall through water due to the resistance of the water. It impacts the motion of objects falling through water by slowing them down until they reach a constant speed where the force of gravity is balanced by the resistance of the water.
