Properties of circular motion:
- Constant acceleration - velocity is constantly changing (speed is the same but direction is changing)
- Acceleration is perpendicular to instantaneous velocity
- Constant Kinetic Energy - speed is constant and direction doesnt have any effect
Process of gravity acting on a body:
1) Gravitational energy stored in a body
2) Work done to move that body to its position in a gravitational field from infinity
3) At infinity there is no force between the masses and zero gravitational energy
4) As the masses get closer the gravitational energy decreases giving a negative value
How a Transformer works:
1) Change in current in primary coil
2) Causes a change in B-field around…
