How is the absolute value of velocity speed?
Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
Why is the absolute value of speed equal to velocity?
It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)
What is the value of negative 9?
negative nine is the value of negative nine
What is the opposite of the absolute value of negative 30?
The opposite is: negative (the absolute value of negative 30).
Can Km be a negative value?
No the Km can never be a negative value. The Km increases or decreases with temperature. An incorrect calculation can produce a negative value.
Is it possible to have negative value in speed and displacement?
No, in physics, speed and displacement are scalar quantities that represent magnitudes and cannot be negative. However, the direction of motion can be indicated by assigning a negative or positive sign to the speed or displacement value.
Is it possible for kinetic energy to have a negative value?
Yes, kinetic energy can have a negative value when an object is moving in the opposite direction of a reference point or when its speed is decreasing.
How is the absolute value of velocity speed?
Velocity is a vector and its magnitude depends on the direction. If it is positive in one direction, going in the opposite direction it is negative. But speed is a scalar and does not depend on the direction. It has the same value, whatever the direction. That is how the absolute value of velocity is speed.
Can acceleration be a negative number?
Yes, the scalar value of acceleration can be a negative number. Acceleration is the rate of change of velocity. If the speed of an object is reducing (it is slowing down), then the object is subject to a negative acceleration. An example is when you apply the brakes in a car. The brakes change the speed of the car from a higher value to a lower value, thus imposing a negative acceleration. Colloquially, people speak of deceleration, however the correct term is negative acceleration.
Does acceleration have a negative or positive value if the velocity is increasing speed?
In this case, acceleration is positive. Negative acceleration would cause the object to slow down (decelerate.)
Why is the absolute value of speed equal to velocity?
It's not. Unless you add a direction to speed it will not become velocity. Since positive and negative are sometimes used to denote direction, absolute value of velocity may equal speed (certain situations)
What is the value of negative 9?
negative nine is the value of negative nine
What does a negative add a positive equal?
If the absolute value of the negative is bigger than that of the positive, then the answer is negative. If the absolute value of the negative is the same, then zero. If the absolute value of the negative is smaller, then positive. Absolute value is the value ignoring the sign.
Does a positive value multiplied by a negative value equal a positive?
No, the product of the multiplication of a positive and a negative value is negative.
How do you figure speed?
Measure the speed at two different points in time. Then take your first value and subtract the second value. A positive value means a gain in speed, a negative number is a decrease in speed, and a value of 0 means no change in speed. The value itself represents how much it has changed. To describe the the change as acceleration you need to divide the change in speed in meters per second, by the time it took in seconds. The SI unit for acceleration is meteres per second per second.
Will a negative number to the fifth power be a positive or negative value?
The result will be a negative value.
WHY SPEED OF AN OBJECT CANNOT BE NEGATIVE?
Speed is (distance covered in some time) / (time to cover the distance).Neither the distance covered in the time, nor the time duration, can be negative.If you'll say "Well what about moving backwards ?", then you have introduced the directionof motion into the discussion, and now you're talking about velocity, not speed. Velocity caneasily be negative, but speed can't.
