Are acceleration and force always in the same direction?

The net force is always in the same direction as the acceleration. For objects moving in circles at constant speed, the net force is directed towards the center of the circle about which the object moves.

Why does acceleration increase as force stays the same?

Remember from working with forces that force is equal to the mass times acceleration. As we increase the force on an object the acceleration increases proportionally. Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration.

What is the relationship of F MA and W MG?

The acceleration obtained by a net-force F is a = F/m. W = mg – Newton’s Law of Gravity: where g = GM/r^2 is the intensity of the gravity FIELD (due to a body of mass “M”), and W is the force of atraction upon a body of mass “m”.

Why is F MA the same as MG?

Newton’s Second Law states: F = ma. F is the net force acting on an object. On earth, the weight of an object is given by W = Mg, where M is its mass and g is the acceleration due to earth’s gravity. Newton’ second law says that object of mass M experiences a force W (its weight) and a downward acceleration g.

How would you describe the magnitude and direction of the forces?

To fully describe the force acting upon an object, you must describe both the magnitude (size or numerical value) and the direction. In contrast, 10 Newton, downward is a complete description of the force acting upon an object; both the magnitude (10 Newton) and the direction (downward) are given.

Is the direction of the acceleration same as the direction of the velocity or opposite?

Acceleration is a vector in the same direction as the change in velocity, Δv. Since velocity is a vector, it can change either in magnitude or in direction. When an object slows down, its acceleration is opposite to the direction of its motion.

How does mass affect acceleration when the applied force is kept constant?

Newton’s second law of motion states that acceleration is directly proportional to net force when mass is constant… and that acceleration is inversely proportional to mass when net force is constant…

How does the direction of acceleration compare with the direction of the net force that produces it?

Acceleration is proportional to net force and inversely proportional to mass. How does the direction of acceleration compare with the direction of the net force that produces it? The acceleration is in the direction of the net force. When gravity is the only force acting on an object, it is in free fall.

What is MG force?

The weight of an object is the force of gravity on the object and may be defined as the mass times the acceleration of gravity, w = mg. Since the weight is a force, its SI unit is the newton. Density is mass/volume.

Is F mg the same as W MG?

The equation for the force of gravity is F = mg, where g is the acceleration due to gravity. The equation also indicates the weight of an object (W = mg). The major feature of this force is that all objects fall at the same rate, regardless of their mass.

Why force has both magnitude and direction?

If there are two forces of the same magnitude and one of them is acting in the east direction and the other in the west direction, the effects of the two forces are different from each other. Thus, to define a force accurately, both magnitude and direction must be specified. A vector has both magnitude and direction.

What is force equal to mass times acceleration?

It is a concise statement of Isaac Newton’s Second Law of Motion, holding both the proportions and vectors of the Second Law. It translates as: The net force on an object is equal to the mass of the object multiplied by the acceleration of the object. Or some simply say: Force equals mass times acceleration.

Does the acceleration vector have the same direction as the force vector?

Here we will show that in the equation F =m a the acceleration vector, a, has the same direction as the net force vector, F. First, recall that when we multiply a scalar times a vector, the result is a vector that has the same direction as the original.

How do you calculate force with a constant mass?

For a constant mass, force equals mass times acceleration.”. This is written in mathematical form as F = ma. F is force, m is mass and a is acceleration. The math behind this is quite simple.

Is acceleration directly proportional to the applied force?

If acceleration is directly proportional to the applied net force, then by whatever factor acceleration changes, force changes by the same factor. To see this we will need to consider an object with constant mass. Let’s consider an object with a mass of 5 kg. Suppose this object has an acceleration of 3 m/s 2. Let’s call this a 1 . So:
