Question
The statements in the following list all refer to the description of motion. Check the boxes
of the THREE TRUE statements.
1. If a particle moves along a straight line with an acceleration that is always equal
to zero, it has a constant velocity.
2. If a stone is launched horizontally with initial speed u from the top of a tower of
height 7, the time taken for the stone to strike the ground is roughly proportional to u.
3. The acceleration vector of a particle in uniform circular motion is perpendicular to
the velocity vector and points radially outwards.
4. If a particle moves round a circle of radius 2.0 m with an angular speed of
3.0 rad s-¹, it has a linear speed of 6 m s-¹.
5. The amplitude of the oscillation for an object undergoing simple harmonic motion
increases when its initial phase increases.
6. If an unpowered satellite travels in circular orbit around the Sun with an orbital
radius that is 4 times greater than the semimajor axis of the Earth's orbit, the satellite
will take 8 years to complete one orbit around the Sun.
