explain why a high speed collision between two cars would cause more damage than a low speed collision between the same two cars?

Answers

Significant transfer of kinetic energy and momentum in high-speed collision causes more damage than low-speed collision.

From the laws of momentum and kinetic energy, a collision between two cars at a high speed would result in more damage than a collision between the same two cars at a moderate speed.

Momentum: An object's momentum is calculated by multiplying its mass by its velocity. The momentum of both cars is a crucial element in a collision. When two cars meet quickly, they have more momentum, which increases the amount of motion and force that is applied to the impact. The two cars' combined momentum increases the force of the collision.

Kinetic Energy: The energy of motion that an object possesses as a result of its mass and velocity. An object's kinetic energy is inversely related to its square of velocity. In comparison to a low-speed accident between the same two cars, the kinetic energy involved in a high-speed collision is substantially more.

A significant quantity of kinetic energy and momentum are transferred to the point of impact when two cars crash at high speed.

In contrast, kinetic energy and momentum are less engaged in low-speed collisions, which leads to less force being applied to the cars and their occupants.

Hence, due to significant transfer of kinetic energy and momentum in high-speed collision causes more damage than low-speed collision.

I've would cause more damage, because there is nore momentum and input force equals output force and the momentum is transferred between the two cars more so than if they had a lower velocity

Where are most faults located? And what is a fault in science terms?

Answers

You can almost ALWAYS find a fault at the edge of a boundary or between the earths' surface and the fault plane. A fault in scientific terms is basically just a crack in the earth's surface that has movement among the fault.

3.why does energy as heat move away from the tropics and toward the pole in the global weather system? 5. A student is reading about predicted upcoming El Niño event. In what way could the student expect to see the global weather patterns change?

Answers

There are three types of heat transfer or heat propagation; conduction, convection and radiation. Heat transfer is the process by which heat projects externally however, depending on the temperature and pressure. Also called the movement of heat from a low temperatured state which increases as heat progresses.
Conduction is the heat transfer by contact, immediate contact.
Convection is the transfer of heat through air and water.
Radiation is the transfer of heat regardless of the presence of atoms or particles.
