P6- Orbital radius

?
What does the force of gravity do?
Holds planets in their orbits
1 of 7
What satellites are man-made?
Artificial
2 of 7
What does the force of gravity lead to?
Change in velocity because direction changes
3 of 7
If speed of satellite increases?
the radius of orbit decreases
4 of 7
Why does this happen?
Cause at a higher speed, greater force of gravity needed to keep it in orbit
5 of 7
As a result of this?
Satellite moves closer to Earth. Gravitational force is bigger. The satellite is stable in orbit.
6 of 7
If speed changes what else has to change?
The radius of the orbit
