Which statement explains how planets move in orbit as supported by Newton’s first law of motion?

Planets can change the direction of their own orbital path.
Planets can change orbits due to their inertia.
Planets in motion will have a constant speed unless acted on by an outside force.
Planets with a greater mass will orbit more quickly than smaller planets.

Respuesta :

Answer:

C

Explanation:

When the planet in motion should have the same speed so until it should be acted by an outer force. This statement explained the movement of the planets.

The information regarding the first law of motion is as follows:

  • In the case when the body is at rest or moves at the same speed on the straight line so it should be the same at rest or a movement until it is acted by an outside force.
  • It is also called as law of inertia.

Therefore, the third option is correct.
