Answer :
The factor that determines the effects of a planetary impact imparted by a collision is the **kinetic energy**. Kinetic energy is the energy an object possesses due to its motion. When two celestial bodies collide in space, the amount of kinetic energy they have plays a significant role in the resulting impact and the changes it brings about.
Here's how kinetic energy influences the effects of a planetary impact:
1. **Higher Kinetic Energy**: If a collision involves objects with higher kinetic energy, the impact will be more forceful and can lead to significant changes such as crater formation, surface disruption, or even alterations to the orbits of the celestial bodies involved.
2. **Lower Kinetic Energy**: On the other hand, collisions with lower kinetic energy may result in less dramatic effects, potentially causing minor surface changes or no noticeable impact at all, depending on the masses and velocities of the colliding objects.
By considering the kinetic energy of the colliding bodies, scientists can better understand the potential outcomes of planetary impacts and the subsequent consequences on celestial bodies in our solar system.
