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

What is the magnitude of the tension in the cord?
Tension = mass(acceleration) + force of gravity Force of gravity equals mass times gravity (9.8m/s2)
What is the formula for force and its components?
Force = Mass x acceleration. The four components of force are: magnitude, direction, point of application, and line of action. Answer by Eliakim Alicea-Perichi
What two factors does acceleration depend on?
-- the magnitude and direction of the force acting on an object -- the mass of the object being forcefully acted upon
What is newtons second low of motion?
The acceleration (a) of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force (F), and inversely proportional to the mass (m) of the object. or F = ma
What is newtons second law and examples?
Newton's second law states that a body of mass m subject to a force F undergoes an acceleration a that has the same direction as the force and a magnitude that is directly proportional to the force and inversely proportional to the mass, i.e., F = ma. This enables you to calculate forces and accelerations of masses.
10 examples of law of acceleration?
-- A car accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the car. -- A stone accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the stone. -- A Frisbee accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the Frisbee. -- A baseball accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the baseball. -- A dog accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the dog. -- A book accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the book. -- A canoe accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the canoe. -- An airplane accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the airplane. -- A planet accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the planet. -- A cow accelerates in the direction of the net force on it, at a rate equal to the magnitude of the net force divided by the mass of the cow.
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.
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".
Is the magnitude of force measured in grams or newtons?
Force is measured in newton. Gram is a unit of mass, not of force.Force is measured in newton. Gram is a unit of mass, not of force.Force is measured in newton. Gram is a unit of mass, not of force.Force is measured in newton. Gram is a unit of mass, not of force.
Rank the pairs of masses in order of increasing magnitude of gravitational force betweenthe masses?
As you increase the mass the magnitude of the gravitational force will increase as well.
What is the magnitude of the tension in the cord?
Tension = mass(acceleration) + force of gravity Force of gravity equals mass times gravity (9.8m/s2)
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.
How much work is done when a vertical force acts on an object horizontally?
It depends on the magnitude of the force and the mass of the object
When you step on a weigh scale what are you really measuring?
You are measuring the magnitude of the gravitational force that attracts your mass towards the center of the Earth, and the magnitude of the gravitational force that attracts the Earth towards you.
What is Murcurys gravitional force?
The acceleration of gravity at the surface of Mercury is 3.7 m/sec2. The force on a mass on the planet's surface depends on the size of the mass. The magnitude of the force, in newtons, is (3.7) times (the object's mass).
What is the magnitude of the force of gravity on a person who has a mass of 80.0 kg?
On Earth 80kg equates to a force of 784.56 newtons.
How much work is done when a vertical force acts on a moving object horizontally?
It depends on the magnitude of the force and the mass of the object
