What is the magnitude of net force acting on a drop of rain falling down with a constant speed?
consider a sphere moving through a viscous medium the fluid layer in contact with the sphere is moving with same velocity but the layer far away is at rest. This makes a relative motion to be setup.viscous force acts on this drop.The backward force is proportional to the speed of the drop.at a stage the viscous force balances the downward force.hence the body moves with a constant velocity called terminal velocity.

What is the direction and magnitude of the net force acting on a rain drop falling down with constant speed?
If the raindrop is falling at a constant speed, then it has reached terminal velocity. This happens when the downward force (due to gravity) is the same as the upward force due to friction. As such the net force acting on the rain drop is 0.
What is the magnitude of force acting on a body moving with constant velocity?
Certainly not. An object has momentum on account of its motion, which depends on its mass and its velocity. Force may be involved in the object's motion, but doesn't need to be. If we let the discussion become somewhat flabby, we can imagine a constant force applied to an object, and asked what happens to the object's momentum. An object with a constant force acting on it exhibits constant acceleration in the direction of the force. In that situation, the object's speed, and therefore its momentum, are proportional to the time the force continues to act on it.
What is the upwars force acting on an object?
The upward force acting on an object is the normal force. It is equal in magnitude, but opposite in direction to the object's weight.
What is the net force acting on a falling object when it reaches terminal velocity?
An object falling at terminal velocity is moving at constant speed (that's what terminal velocity means) and we will assume it is not changing direction (i.e. it is falling straight down; in reality it is more likely to be bobbing and weaving on the wind.) Constant speed and direction is another way of saying constant velocity. when an object is acted upon by a net force, it's velocity changes. So, since we know that the velocity is not changing, there is no force.
How do you find force when given a constant speed and force of friction?
If the speed is constant, then the group of forces acting on the object is balanced. So the portion of the force acting in the direction of the motion must be equal and opposite to the force of friction.
What is the direction and magnitude of the net force acting on a rain drop falling down with constant speed?
If the raindrop is falling at a constant speed, then it has reached terminal velocity. This happens when the downward force (due to gravity) is the same as the upward force due to friction. As such the net force acting on the rain drop is 0.
If you push a crate across a factory floor at constant speed in a constant direction what is the magnitude of the force of friction on the crate compared with your push?
The magnitude of the force of friction on the crate would be equal to the magnitude of your push. This is because the crate is moving at a constant speed, indicating that the force you are applying is balanced by the force of friction acting in the opposite direction.
How do you find magnitude of force by using a constant speed?
If an object is moving at a constant speed, the net force acting on it is zero according to Newton’s first law of motion. This means that the magnitude of the force required to maintain that constant speed is equal in size but opposite in direction to any external forces acting on the object, such as friction or air resistance.
How do you you calculate the magnitude of the force acting on a charge?
You can calculate the magnitude of the force acting on a charge using Coulomb's law. The formula is F = k * |q1 * q2| / r^2, where F is the magnitude of the force, k is the Coulomb's constant, q1 and q2 are the charges, and r is the distance between the charges.
If we push a crate at a constant velocity how do we know how much friction acts on the crate compared to our pushing force?
If the crate is moving at a constant velocity, then the force of friction acting on the crate is equal in magnitude and opposite in direction to the force you are applying to push the crate. This means that the force you apply to push the crate is balancing out the force of friction acting against it. By measuring the force you are exerting and observing the constant velocity of the crate, you can infer the magnitude of the friction force.
How is force acting on a falling object?
The force acting on a falling object is the gravitational force, which pulls the object towards the center of the Earth. This force causes the object to accelerate downwards, leading to its motion. The magnitude of this force is determined by the mass of the object and the acceleration due to gravity.
What is the net force on an object with constant velocity?
If the object is moving in a straight line, then the net force on it is zero. If the object is not moving in a straight path, then there is some non-zero net force acting on it even if its speed is constant. We don't have enough information to describe the magnitude or direction of the force.
When a body moves with constant velocity what is the magnitude of net force is the magnitude of force applied to keep the body moving equal to less than or more than frictional force explain?
When a body moves with constant velocity, the net force acting on it is zero as there is no acceleration. The magnitude of the force applied to keep the body moving is equal to the frictional force opposing its motion. This ensures that the forces are balanced, resulting in a constant velocity without any acceleration.
When you drag force on an object falling through the air equals the force of gravity the object has reached?
Thermal Velocity
If a book is falling through the air what is the force acting on it besides gravity?
The main force acting on a falling book, besides gravity, is air resistance or air drag. As the book moves through the air, the air molecules exert a force in the opposite direction of motion, which opposes the book's downward movement. The magnitude of this force depends on factors such as the speed and size of the falling object.
What is the normal force acting on a book that is sitting on a desk?
The normal force acting on a book sitting on a desk is equal in magnitude and opposite in direction to the force of gravity pulling the book downward. This force prevents the book from falling through the desk and is what keeps the book in place.
If you push a crate with a force of 100 N and it slides at a constant velocity how much is the friction acting on the crate?
If the crate is moving at a constant velocity, the friction force is equal in magnitude but opposite in direction to the pushing force, so it is also 100 N. This is because the two forces are balanced and there is no net force acting on the crate.
