A space probe is carried by a rocket into outer
space where it continues to move on its own
in a straight line.
What keeps the probe moving?
Is the answer: the gravitation forces from different stars
and planets
Please it is important!
no. Inertia. What is Newtons first law of motion?
The answer is not the gravitational forces from different stars and planets. Once the space probe is launched into outer space, it continues to move on its own in a straight line due to the principle of inertia. Inertia is the resistance an object has to changes in its motion. In the vacuum of outer space, there is no significant drag or friction to slow down the probe, allowing it to continue moving without any external forces acting upon it.
The answer to your question depends on the specific situation and the design of the space probe. In general, there are a few factors that can keep a space probe moving in outer space once it has been launched:
1. Initial Velocity: When the space probe is launched by a rocket, it is given a significant amount of initial velocity. This velocity allows the spacecraft to overcome Earth's gravity and continue moving in outer space.
2. Inertia: Once the space probe is in motion, it will continue to move unless acted upon by an external force. This is known as the principle of inertia, which is a fundamental concept in Newtonian physics. Inertia allows the spacecraft to maintain its velocity and direction in the absence of external forces.
3. Gravitational Forces: While the gravitational forces from stars and planets can have an influence on the motion of a space probe, their effect is relatively small compared to the initial velocity and the principle of inertia. In most cases, space probes are designed to travel in a specific trajectory, taking into account the gravitational forces from celestial bodies along their path.
It's important to note that in the vacuum of space, where there is no air resistance or friction, a space probe can continue moving indefinitely with its initial velocity, unless it encounters other gravitational forces or is affected by other external factors such as collisions with objects or the activation of its own thrusters.
