Electric Motor:
A device, which converts electric energy into mechanical energy is known as Electric Motor.
Factors on which the speed of Rotation of Motor Depends:
The speed of rotation of motor depends on the following factors.
1. Magnitude of current passing by the motor.
2. Strength of magnetic field.
3. Number of turns in the coil of the motor.
4. Permeability of its armature.
Inertia with a spade Scoop up a spadeful of dry earth. Now pitch the earth away from you. View that when the spade stops the earth flies on due to inertia.
TIME OF FLIGHT: "It is the total time for which the projectile remains in air". As, the body goes up and comes back to similar level, so it does not cover vertical distance,
suppose you are running and want to stop at once. surely you will have to produce negative acceleration in your speed. can you tell from where does the necessary force come ?
list the factors used to classify inductors.
A ROCKETSHIP IN FREE SPACE MOVES WITH CONSTANT ACCELERATION OF 9.8 METER PER SECOND SQUARE. IF IT STARTS FROM REST HOW LONG IT WILL TAKE TO ACQUIRE A SPEED ONE-TENTH THAT OF LIGHT
