When a net force acts on that object, there is a change in velocity, and thus acceleration.

∙ 7y agoThat's the rate of change of its velocity - how fast its velocity changes. In symbols:
a = dv/dt.
In the SI, a speed, as well as a velocity, are expressed in meters/second; thus, the natural unit for acceleration is (meters/second)/second, usually written as meters / second squared - since you need to divide a velocity (more precisely, a change of velocity) by a time.
Note that since velocity is a vector, so is acceleration.

What is the relationship between weight and accelaration?
'RELATIONSHIP' 'between' implies -two- things, I assume you mean 'between force and acceleration'. The relationship between 'force' and 'acceleration' is explained in your physics book or class. F = MA, or force equals mass times acceleration, that means, as an example, 'weight', or force towards the center of the earth, is equal to 'mass', which is 'density' of an object, like a rock or a car or a person, would mean the object has more atoms, electrons, quarks, nuons neons or nouns than another object. In comparison measurement to that other object (and,as the earth has been around - forever, as far as you or I could really tell, it was considered 'flat' and 'the only one', and a 'garden', and may have been - at one time in the far distant past, maybe. But our 'weight' is only a measurement of some arbitrary, long ago manmade number, that today has grown into ounces and pounds. Some individual long ago made that his measurement number. So, your weight is relative ... to someone else's. and theirs to a lot of other measurements, that are gradiated, and listed as standards. I read once that the 'inch' was a 'ye-olde' British King's length from his knuckle to the tip of one of his fingers. It was set as a standard. Back then, none were available, that was the beginning of standardization. Today, the 'meter' is more generally accepted in other countries, and is defined as '100 centimeters', and a centimeter is defined as a large, set number cycles of one frequency, a very fast frequency, so that the large count would be very accurate. No more random king-thumbs. doveshawk
How fast would a 75 kilo male fall from 12000 feet?
The acceleration of an object that falls from a certain height does not depend on its mass, in an ideal condition with no air resistance. The value of acceleration is the acceleration due to gravity, which is 9.81 m s-2. <><><><><> However, in this case, air resistance is going to matter. 12000 feet is high enough for the person to accelerate to what we call terminal velocity. Terminal velocity is the velocity where the force of acceleration due to gravity (9.81 m s-2) is matched by the air resistance. That velocity varies, depending on the outline shape of the person, and is typically around 200 km/h or 125 mph. That will be the velocity of the fall.
What are the 3 factors of weight?
The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.
Why the mutual force of attraction between apple and earth is equal and opposite but the apple moves towards the earth appear to be at rest?
The Earth is more massive. The same force will result in less acceleration on a more massive object (Newton's Second Law).
What is the relationship between acceleration and mass?
well the relationship between mass and force is..........*relationship... Force=mass x acceleration
What happens to the acceleration of an object's if the force on the object increase?
its acceleration will be increased
What happened to the acceleration of an object if the force on the object increases?
its acceleration will be increased
What happens to acceleration of an object as its mass decreased?
The acceleration of the object increases.
What happens to the acceleration of an object if the force on the object increases?
its acceleration will be increased
What happens to the acceleration of an object as its mass decreases?
Acceleration is a net force that is inversely dependent on mass, therefore if an object's mass decreases, acceleration increases.
If acceleration equals gravity. what is the weight of the object?
Object's weight = (object's mass) multiplied by (acceleration of gravity in the place where the object is)
What is the rate at which an object velocity changes?
Acceleration
When forces are balanced compare the acceleration of an object at rest and an object in motion?
An object at rest has zero acceleration. If the set of forces acting on a moving object is balanced, then the moving object also has zero acceleration.
What affects the acceleration of an object?
An object's acceleration is the result of a force being applied to it. When that happens, the magnitude of the resulting acceleration is equal to the force divided by the object's mass, and the direction of the acceleration is in the direction of the force.
Can an object have zero acceleration and eventually-reverses its acceleration?
I am not sure what you mean by reversing a zero acceleration. An object's acceleration can, of course, change over time.
If you increase the force on an object what happens to the acceleration?
If you increase the force on an object acceleration increases . As F = m*a, where F = Force , m = mass of the object & a = acceleration
What happen to the acceleration of an object if the force on the object increases?
Acceleration is a net force that is inversely dependent on mass, therefore if an object mass increases ,acceleration decreases
