1. Draw free-body diagrams for each of the following objects in uniform circular motion. State the force(s) providing the centripetal force. a )The Earth orbiting the Sun b) A car making a curve on a horizontal road c) A ball on a string swinging in circles on a horizontal surface (1') A ball on a string swinging in circles in the vertical plane a at the top of the circle a at the bottom of the circle e) A ball on a string swung in circles in a horizontal plane in mid-air such that the plane of the circle is below the end of the string held at the centre of the circle. f) A pilot in a plane making a vertical circle in mid-air c at the top of the loop (she is upside down at this position. as is the plane) a at the bottom of the loop
