Explanation:
Newton's second law of motion states that when a certain force is acted on an object then it is equal to the mass m of that object multiplied by the acceleration a of the object.
Mathematically, the relation is as follows.
F = m × a
Thus, we can conclude that when an object is acted on by an unbalanced force then the object will start to accelerate.
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.
