What is the value of y when the value of x is 3?
It depends on the relationship between x and y.
Approximation of sin x by x?
the value of sin(x) lies between -1 to +1. the approx value of sin(x)/x = 1 when x tends to 0 & sin(x)/x = 0 when x tends to infinity.
Find the value of 2x² when x equals 3?
18
What is the limit of sin x?
Sin(x) has a maximum value of +1 and a minimum value of -1.
X plus x plus x equals 180 then what is the value of x?
60
When acceleration upward or downward direction is taken positivw or negative?
If it is gravitational acceleration then it it is positive in downward and negative in upward direction..if it is not gravitational acceleration then it is depending upon the value of acceleration.
What is the ratio of force to acceleration?
The ratio is the M/cos(x). where M is the mass on which the force is acting and x is the angle between the direction of the force and the direction of the acceleration.
Is acceleration due to change in direction?
Acceleration is defined as the change in velocity, and is a result of a force being applied on the object in question. Acceleration will not always result in an object changing direction, but it is capable of it (in the case of centripetal acceleration, all it does is change the direction.) Acceleration is a vector, therefore a direction must always be given when a value is stated.
A classmate in the physics state that the negative acceleration always mean that a moving object is decelerating is that true?
It is not true. It means that the object MIGHT be decelerating but not "always" (as your friend says). Instead, think of it this way... We start by clarifying that there is no such thing as "negative acceleration" per se. That is, that acceleration is a vector composed of an absolute value scalar and a direction. So "negative acceleration" actually refers to an acceleration which just happens to be in the negative direction of whatever coordinate system you've chosen to define for the particular problem. We define a coordinate system (for a two dimensional universe to keep things simple) with positve/negative x and y. If the object starts out already moving in the positive X direction, then to apply an acceleration in the negative direction would mean there is deceleration. If the object is stationary or moving in the negative X direction, then applying an acceleration in the negative X direction would actually be accelerating the object. In other words, the reference from has to stay constant for there to be meaningful discourse on the subject. By the same note, even moving in the positive X direction, if the object is acclerated in the negative Y direction then the object is actually accelerating.
How do you work out the deceleration?
Same as acceleration - just remember that "deceleration" is an acceleration in a direction opposite to the direction of movement.Same as acceleration - just remember that "deceleration" is an acceleration in a direction opposite to the direction of movement.Same as acceleration - just remember that "deceleration" is an acceleration in a direction opposite to the direction of movement.Same as acceleration - just remember that "deceleration" is an acceleration in a direction opposite to the direction of movement.
Is Centripetal acceleration a vector?
Um, well... it can be represented by a vector.Just like anything else that has both a direction and a value.The mere numerical value of an acceleration is not a vector,since it's just a value without a direction.
What shall you do when you find the value of driving force is negative?
The acceleration is in the direction of the positive force so you will have deceleration in the direction of the negative force.
When a cart is changing direction is it acceleration?
Consider a graph paper with Axis X and Y. Cart travel in X direction but suddenly, the cart change direction and so it must reduce velocity on X and increase velocity on Y. Net velocity might be the same but small acceleration and deceleration is apply in 2 dimension motion.
What is acceleration since it has magnitude and direction?
Acceleration is a vector quantity because it has both magnitude and direction.
Does change in direction cause acceleration?
Not necessarily. Changing direction does affect the velocity, which is acceleration and direction combined.
What is the direction of instantaneous acceleration?
The acceleration can be in any direction; it depends on the specific situation.
Why at a constant speed if an object changes its direction it is considered to be acceleration?
Acceleration is a direction plus a speed. If either changes then the acceleration changes.
