(a)[1]
State the difference between speed and velocity.
(b(i))[2]
Explain, using its velocity, why the satellite is accelerating.
(b(ii))[1]
On Fig. 1.1, draw an arrow that begins at the satellite to show the direction of the satellite’s acceleration.
(c)[2]
As the satellite moves around the Earth, it is acted on by a force from gravitational attraction. State and explain whether this force does work on the satellite and state whether the energy of the satellite is affected.
