What else can I help you with?
What is momentam?
The moment of linear momentum is called angular momentum. or The vector product of position vector and linear momentum is called angular momentum.
What is the electromagnet in enelectric motor called?
The electromagnet in an electric motor is typically called the rotor or the armature. It is the part of the motor that rotates when an electric current is passed through it, generating mechanical energy.
What is the point around which a lever rotates called?
The point around which a lever rotates is called the fulcrum. It is the fixed point or pivot on which the lever moves when a force is applied.
What is switch called that rotates with an electromagnet?
A rotary switch.
Why angular speed is called angular frequency?
Angular speed and angular frequency are used interchangeably to describe the rate of change of angle with respect to time in circular motion. The term "angular frequency" is specifically used in the context of periodic motion to indicate the frequency of angular displacement or rotation. It is often measured in radians per second.
Why does earth have 24 hours in a day?
It rotates so that it has day & night. The speed of that rotation is the remnant of the angular velocity imparted by the collision that formed the moon. The fact that that interval is called 24 hours is purely arbitrary and is derived from some ancient civilization being fascinated by base 12 math and dividing day-light into 12 equal parts.
Why does the earth spin in space?
The Earth spins in space due to an action called angular momentum. The Sun is considered the fixed point of the Earth, which is why the Earth rotates around the Sun.
What motion is a second hand watch moves through a complete circle every minute?
That motion is called angular motion. The angular speed of the second hand is 2pi radians per minute.
What is the imaginary line through Earth's poles called?
The imaginary line through Earth's poles is called the axis. It is an imaginary line that Earth rotates around.
Where is the arbitrary line located at?
Wherever the person defining it choses to place it. That is why it is called arbitrary.
The earth rotates on what is called?
The Earth rotates on an invisable axis.
Why does earth rotate constantly?
Actually it doesn't - but the changes are quite small. There is a physical law called Conservation of Angular Momentum - the total angular momentum (informally, we might say the "amount of rotation") can't increase or decrease in a closed system. If the distribution of masses on Earth changes, Earth's angular velocity can change - but any redistribution of masses is rather small-scale, compared to the size of the Earth. On the other hand, Earth rotates slower and slower over time - angular momentum is transferred to the Moon in this case.
What is momentam?
The moment of linear momentum is called angular momentum. or The vector product of position vector and linear momentum is called angular momentum.
What does the earth rotate or spin on?
Its axis The earth rotates around its axis - an imaginary line running from the North Pole through the centre of the earth to the South Pole. It rotates around this line once every day. it is this rotation which causes day and night. axis
The earth rotates on what is called its?
The Earth, and all rotating planets, rotates on its axis.
A deposit of fine-grained angular particles is called?
A deposit of fine-grained angular particles is called a breccia. Breccias are formed from the accumulation of broken rock fragments that are typically angular in shape and can vary in size.
What is a circle?
A circle is the set of all the points that are the same (arbitrary) distance (called the radius) from some (arbitrary) point (called the center).
