Beech Grove Chapter 14 Review Satellite Motion

If we drop a ball from rest, how far will it fall vertically in the first second?

• 5m

• 10m

• 9.8m

• 1.5m

If we throw a ball horizontally, how far will it fall in the first second

• 10m

• 5m

• 9.8m

• 1.5m

What do the distances 8000m and 5m have to do with a line tangent at the Earth's surface

• Earth's surface drops 5m below a tangent line at 8000m

• Earth's surface drops 8000m below a tangent line at 5m

• The Earth curves at a distance of 5m

• There is no connection between these distances

Does the direction of a circular orbiting satellite compare with the curve of the Earth

• Yes the path is parallel to the surface below

• No there is no comparison

Does Gravitational force change the the speed of a circular orbiting Satellite

• Yes, the force changes at each point of orbit

• No there is no component of force in a circular orbit

Does the period of a circular orbiting satellite change as its distance from Earth increases

• Yes it decreases

• Yes it increases

• No change with increase of distance from Earth

In an Elliptical orbit, where is the speed of the satellite greatest

• Perigee

• Apogee

• Speed does not change

In an Elliptical orbit, where is the speed of the satellite lowest

• Perigee

• Apogee

• Speed does not change

Is the sum of KE and PE constant in a circular orbit

• Yes

• No

Is the sum of KE and PE constant in an elliptical orbit

• Yes

• No
