What is relationship between frequency and amplitude?
Frequency is inversely proportional to amplitude.
Can amplitude of sine be negative?
The difference with a negative value of a however, is our sine curve now has a negative amplitude. In other words, our graphs are the same as when a was a positive value, but are now reflected across the x-axis. Notice how different values of a change the amplitude of our sine curve.
Why is the amplitude negative?
An amplitude cannot be negative since it is defined as a half the distance, which cannot be negative, between the maximum value and the minimum value.
What does the amplitude of this function represent?
The height from the center line to the peak (or trough) of a periodic function. Or we can measure the height from highest to lowest points and divide that by 2.
What is the amplitude of an angle?
Angles: An area marked by two line segments with the same origin. a: Side one, or in other words, one of the line segments that create the angle. Together with the other side, it marks out the angle’s amplitude.
Can amplitude be a degree?
For a true pendulum, the amplitude can be expressed as an angle and/or a distance. Every angle can be expressed in degrees, also in radians. Regarding your equation, x = A cos it’s customary for A (the amplitude) to be a distance, although it can just as well be an angle.
What is amplitude class 8?
The maximum displacement of a vibrating object from its Central position is called the amplitude of vibration. The amplitude actually tell us how far the vibrating object is displaced from its central position.
What are lubricants Class 8?
Lubricant is a substance used to reduce friction between surfaces in contact which reduces heat generated when the surfaces move. The property of reducing friction bisetween two particles is known as lubricity. Example: oil, grease.
Why are lubricants used Class 8?
When friction is undesirable we have to reduce the friction. Friction can be minimized by using lubricants like oil and grease and by using ball bearing between machine parts. A substance that is introduced between two surfaces in contact, to reduce friction, is called a lubricant.
What is lubricant give an example?
A lubricant is a substance which introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. For example – motor oil, friction modifier, friction additive, gel, silicons, flourocarbons, ect.
