Hi -

I've completed a quiz relating to the questions below, but before submitting would be grateful for one of your experts to give their thoughts.

Many Thanks

The statements in the following list all refer to the description of motion. Which are the THREE TRUE statements.

1. It is possible for a particle to move along a straight line with a positive instantaneous acceleration (a_x>0), and to be slowing down.

2. When a package is dropped from an aircraft flying horizontally, it hits the ground at a point vertically below its point of release from the aircraft.

3. If two particles move in uniform circular motion in circles of radii r₁ and r₂ respectively, and each takes the same time to complete one orbit, the particle with the greatest radius of orbit has the greatest magnitude of acceleration.

4. If a particle undergoes uniform circular motion in a horizontal plane, moving clockwise around a circle as seen from above the plane, the angular velocity vector of the particle points vertically upwards.

5. In simple harmonic motion, the magnitude of the acceleration of the particle is greatest when the particle is instantaneously at rest.

6. Each planet moves in a ellipse around the Sun with the Sun at the intersection of the major and minor axes of the ellipse
