What happens when 2 asteroids collide?

A giant collision between two asteroids may have triggered a global ice age that hit Earth some 466 million years ago. The cosmic crash — which took place between Mars and Jupiter and destroyed an asteroid some 93 miles (150 km) wide — created a thick plume of dust that spread throughout the inner solar system.

What is pushing on the asteroid to make it spin?

When sunlight hits the asteroid, the solar energy is absorbed and then radiated back into space. When the asteroid is not spherical, this can create a push off parts of its surface that alters its spin.

How does mass affect the force of the asteroid?

Since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

When two asteroids collide and merge the collision is considered group of answer choices?

When two asteroids collide and merge; the collision is considered elastic inelastic Question 7 1.5 pts Imagine bomb exploding into three fragments of equa masses while exploding At what angles will they fly away compared to one another?

Why are collisions between asteroids in the asteroid belt rare?

The first crossing of the asteroid belt took place in the early 1970s, when the Pioneer 10 and Pioneer 11 spacecraft journeyed to Jupiter and beyond. In fact, such a risk is minuscule because there is a tremendous amount of space between Mars and Jupiter and because the objects there are very small in relation.

Do asteroids hit the Sun?

No asteroids have ever been observed to hit the Sun, but that doesn’t mean that they don’t! Asteroids are normally content to stay in the asteroid belt between Mars and Jupiter, but occasionally something nudges them out of their original orbits, and they come careening into the inner solar system.

What makes an asteroid move?

Their surfaces heat up during the day and cool down at night, giving off radiation that can act as a sort of mini-thruster. This force, called the Yarkovsky effect, can cause rotating asteroids to drift widely over time, making it hard for scientists to predict their long-term risk to Earth.

Does asteroids have gravitational force?

Most asteroids are very small but they do have gravity and can affect any objects that come too close. The more iron (Fe) and nickel (Ni) in the makeup of an asteroid, the greater its mass (and gravity). Scientists also use the amount of metal in asteroid classification.

Why do asteroids explode in the air before hitting the ground?

Many asteroids explode in the air before they ever reach the ground. As they travel through the air at a velocity of 15-20 kilometers per second, they experience huge pressure forces due to the enormous air resistance felt at this high speed. These pressure forces cause the asteroid to explode violently.

How do you calculate the impact energy of an asteroid?

You can easily estimate the impact energy of an asteroid. You do this by calculating the kinetic energy of the asteroid just before it strikes the earth. This is equal to the impact energy. Kinetic Energy = (1/2) MV2

What happens when a 5 kg object accelerates to the right?

As the 5.0-kg object accelerates to the right, it will be pushing rightward upon the 10.0-kg object; this is known as a contact force (or a normal force or an applied force or …). The vertical forces balance each other since there is no vertical acceleration.

What is the kinetic energy of a 20 km/s asteroid?

V is the velocity of the asteroid just before it strikes the earth For example, consider an asteroid that is one kilometer in diameter and weighs 1.4 billion tonnes (M = 1.4×10 12 kilograms), and is traveling at 20 kilometers per second (V = 20,000 m/s). The kinetic energy would be equal to (1/2)×1.4×10 12 × (20,000) 2 = 2.8×10 20 Joules.
