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 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.
Adding a force acting in one direction to a force in another direction is the same as adding a?
as adding a ".... in the opposite direction.
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.
If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
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.
Does a car traveling along a curved path at constant speed have a constant momentum?
Yes, a car traveling along a curved path at constant speed does not have constant velocity since velocity is a vector quantity that includes direction. However, the magnitude of the car's momentum (which is the product of mass and velocity) can remain constant if there are no external forces acting on it.
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.
If a car is moving at a constant speed of mph is it balanced or not balanced?
If a car is moving at a constant speed, it is in a state of balanced forces. The forces acting on the car are equal in magnitude and opposite in direction, resulting in no change in its speed or direction.
What two things do force have?
Magnitude and direction.
What are the four ways objects move in force?
Objects can move in response to a force by accelerating, decelerating, changing direction, or maintaining a constant velocity. These movements are determined by the magnitude and direction of the force acting on the object.
What describes an object with constant velocity?
Constant speed, moving in a straight line, zero acceleration, zero net force acting on it.

The velocity of an object includes?
The velocity of an object includes both its speed (magnitude of the velocity) and its direction of motion. It is a vector quantity that describes how fast and in which direction an object is moving. Velocity can be constant or changing depending on any accelerations acting on the object.
All forces have what two properties?
All forces have magnitude, which represents the strength of the force, and direction, which indicates the way in which the force is acting.
Determine the magnitude and direction of F so that the particle is in equilibrium?
To have equilibrium, the net force acting on the particle must be zero. The magnitude of force F must be equal in magnitude (but opposite in direction) to the resultant of all other forces acting on the particle. Therefore, to determine F, you need to calculate the vector sum of all other forces acting on the particle and then determine the magnitude and direction for F.
What does a force vector show about the push or pull of an object?
A force vector shows the direction and magnitude of a push or pull acting on an object. The direction of the vector indicates the direction in which the force is acting, while the length of the vector represents the strength or magnitude of the force.
