32 HW Orbital Motion Interactive NEW

If a satellite is orbiting the Earth in an elliptical motion, then it will move _______________ (slowest, fastest) when its closest to the Earth.

fastest

Describe the object's velocity during the course of the elliptical orbit.

velocity is changing its direction and magnitude

Describe how an alteration in eccentricity of the orbit effects the elliptical and circular nature of it.

the greater eccentricity makes more elliptical shape

What eccentricity value results in a circular orbit?

0

Force is a vector quantity which has both _.

magnitude and direction

For circular obits:
The direction of the velocity of the satellite is ___________________ (always, seldom, never) perpendicular to the net force acting upon the satellite.

always

Describe the net force acting upon the object during the course of the elliptical orbit.

force is changing its magnitude and direction

While moving towards the Earth (along the path from D to A) there is a component of force in the __________________ (same, opposite) direction as the motion;
this causes the satellite to ___________________ (slow down, speed up).

same, ... , speed up

Velocity is a vector quantity which has both _.

magnitude and direction

Describe how an alteration in eccentricity of the orbit effects the elliptical and circular nature of it.
Responses

smaller eccentricity will make more circular shape

While moving away from the Earth (along the path from A to D) there is a component of force in the _________________ (same, opposite) direction as the motion;
this causes the satellite to ___________________ (slow down, speed up).
Responses

opposite, ... , slow down

Describe how an alteration in eccentricity of the orbit will change velocities and forces during the orbit.

increase in eccentricity will increase the difference in velocities and forces
