Electric motors can seem very mysterious! How do they use electricity to start rotating? Let's break it down step by step to understand how it works. Topics covered in this video: circuits, current, magnets, electromagnets, armature, commutator, brushes, stator, and rotor. This video only covers DC motors. Maybe I will cover AC motors in a future video????

Projectile motion down an incline Projetile motion thrown from a higher point. The angle of projection and angle of incline both are measured from a horizontal line. ... Components of acceleration due to gravity Accelration due to gravity forms an angle with y-direction, which is equal to angle of incline.
What is the formula for Inclined Plane? It can be divided into two components: Fi = Fg * sinθ - parallel to inclined plane. Fn = Fg * cosθ - perpendicular one.
What is the velocity of body at maximum height in inclined projectile motion? Maximum Height
At the highest point of the trajectory, vertical component of velocity is zero.
What are the 3 types of inclined planes? Inclined Planes Examples Wheelchair ramps. Slides. Stairs. Waterslides.
To calculate internal resistance, we use a potentiometer to first calculate the voltage across the battery, with no current through it. Then we attach a resistor in parallel to the battery and recalculate the voltage across it. Since the current flows, this time the balancing length is smaller.
