Question

In deep space there is very little friction once they are launched into a probe into deep space where there are no external forces acting on it scientists shut the probe's engines off because the scientists want the probe to

Answer 1

Continue on the momentum it has. The probe will continue in the same direction it is moving because there are no forces to act against it. I think this is the answer you are looking for...?

Answer 2

move at a constant velocity

Step-by-step explanation:

When the friction is present the engine helps move the probe by constantly doing work against the friction. But when the friction is absent then there is no need for the engine to work all the time. According to newton's first law, no object can change its state of rest or uniform motion with constant velocity without an external force. When the engine is shut off, the probe will continue to move at a constant speed due to inertia.
