The direction of rotation of a motor be changed by reversing two of its stator leads.
Electric motor is the electro-mechanical machine which converts the electrical energy into mechanical energy. In other words, the devices which produce rotational force is known as the motor.
In order to reverse the direction of an AC motor, we need to change the magnetic field the to make the movement in the opposite direction. As we change the direction of magnetic field , force will also get reversed by using Fleming's left hand rule .
Since each wire consists of a positive and negative current within the magnetic fields, the flip-flopping of main and starter wires causes the motor to run in reverse rotation
Hence, the direction of rotation of a 3-phase motor can be changed by reversing two of its stator leads.

Mass is the physical quantity
We can see that the range from the calculation is 310 m.
<h3>What is the range of a projectile?</h3>
When we throw something from a height and it lands at the same eight, we call it a projectile motion. A projectile must always be shot at an angle. The range of the projectile is obtained by the relation; R = u^2sin2θ/g
Thus;
g = acceleration due to gravity
θ = acute angle
u = velocity
R = (60)^2 sin2(30)/10
R = 310 m

Power is the rate that work is done or work per unit time.
So doing more work per unit time creates more power.
Power = Work / time
