Answer
The correct answer is row C: force is a vector and velocity is also a vector. Force has both magnitude and direction, while velocity indicates the speed and direction of an object.
Step 2
State the name of the force that keeps the satellite in orbit around the Earth.

Answer
The force that keeps the satellite in orbit around the Earth is called gravitational force.
Step 3
Draw an arrow on Figure 20 to show the direction of the force acting on the satellite, that keeps the satellite in orbit around the Earth. Label this arrow 'F'.

Answer
In Figure 20, draw an arrow pointing from the satellite towards the center of the Earth. This arrow represents the gravitational force acting on the satellite, and it should be labeled 'F'.
