If the subway car is moving at a constant velocity, meaning its acceleration is zero, then the net force is zero. Fnet = ma.

What two factors does acceleration depend on?

Acceleration depends on both the magnitude of the net force acting on an object and the mass of the object. The greater the net force applied or the lower the mass, the greater the acceleration of the object.


What is the mathematical relationship between force and acceleration?

Force in Newtons = mass in kilograms * acceleration ( can be gravitational acceleration )F = maThe mathematical relationship between force and acceleration is directly proportional.


What is the magnitude of the tension in the cord?

The magnitude of tension in a cord is the force exerted by the cord to maintain equilibrium in a system. It is equal in magnitude but opposite in direction at each end of the cord, keeping the system balanced. The tension is influenced by the weight of the objects the cord is supporting and any external forces acting on the system.


How to calculate the normal force acting on an object held against a wall given mass and force?

The normal force is equal in magnitude but opposite in direction to the force applied against the wall. If the object is held against the wall with a force, then the normal force acting on the object will be equal in magnitude to that force. If the mass of the object is given, you can calculate the force needed to hold it against the wall using Newton's second law (F = ma).


How does mass and acceleration are related and specify if these scalar or vector qualities?

Increasing the mass decreases the acceleration. Newton's Second Law: F = ma (Force = mass x acceleration) --> a = F/m, meaning that the relationship between the acceleration and the mass is inversely proportional. Mass is a scalar quantity because it doesn't have direction. Acceleration is a vector quantity because it has both magnitude and direction.

How do you find the magnitude in force?

To find the magnitude of a force, you can use the equation F = ma, where F is the force, m is the mass, and a is the acceleration. By multiplying the mass and the acceleration, you can determine the magnitude of the force acting on an object.

How does mass affect the magnitude of gravitational force?

The magnitude of gravitational force between two objects is directly proportional to the product of their masses. This means that as the mass of one or both objects increases, the magnitude of the gravitational force between them also increases. In simpler terms, the more massive an object is, the stronger its gravitational pull.

What are the factors associated with the magnitude of force?

Mass n acc Answer2: Force is F = XE = [d/dr, Del] [Epotential, Evector], the spatial rate of change of energy. If the change of energy is high, the magnitude of force is high. Force is not always related to mass or acceleration, for example with electromagnetic force.


Is mass the magnitude of the force due to gravity on an object?

No mass is not the magnitude of the force due to gravity on an object. Mass is the stuff of which the object is composed. The magnitude of the gravitational forces between the object and Earth ... or whatever planet the object happens to be on ... is the object's "weight".


What are the three things that the magnitude of the Coriolis Force depends?

The magnitude of the Coriolis force depends on the speed of the object, the latitude at which the object is located, and the mass of the object.


What does the magnitude of the gravitational force between two bodies depend on?

The magnitude of the gravitational force between two bodies depends on the mass of the bodies and the distance between them. The larger the mass of the bodies, the greater the gravitational force, and the closer the bodies are, the stronger the gravitational force.


Can force change the magnitude of a body?

Yes, force can change the magnitude of a body.


Which of the following are vectors speed force mass displacement time velocity energy momentum?

Where does the magnitude of force depends?

The magnitude of force depends on the mass and acceleration of an object, as described by Newton's second law of motion (F = ma). The force exerted is directly proportional to the mass of the object and the acceleration it experiences.


What affect the magnitude of force?

Gravitational Force = Gravitational Constant x mass of the first object x mass of the second object / distance squared. So what affects the magnitude is the masses of the objects and the distance between them. Gravitational Constant = 6.672 x 10^-11 N x m^2/kg^2 Both masses, and the distance between them.
