Question 161

A deep-space probe approaches and passes close to a massive asteroid.

What effects can the gravitational force exerted by the asteroid have on the motion of the probe?

A

It can only change the direction of the probe's velocity.

B

It can change the direction of the probe's velocity, increase its speed, or decrease its speed.

C

It can change the direction of the probe's velocity or increase its speed, but never decrease its speed.

D

It can increase or decrease the speed of the probe, but it is unable to change its direction.
