Question

Почему нельзя мгновенно остановиться или мгновенно набрать большую скорость? ​

Answer 1

Ответ:

На разгон требуется энергия, которую при движение нибираешь, а при остановке ты будешь двигатся по инерции и потом только остановишься.

Answer 2

Why can't you instantly stop or instantly accelerate?

When it comes to stopping or accelerating, there are several factors that prevent us from doing so instantly. Let's explore these factors in more detail:

Stopping: 1. Inertia: Inertia is the resistance of an object to changes in its state of motion. When you try to stop suddenly, your body and the objects around you still have momentum, which is the product of mass and velocity. Overcoming this momentum requires time and force.2. Friction: Friction is the force that opposes motion between two surfaces in contact. When you try to stop, friction between your feet and the ground is necessary to slow you down. However, friction also takes time to act, and it depends on the nature of the surfaces involved.3. Reaction time: Even if you decide to stop instantly, your body needs time to send signals to the muscles and initiate the necessary actions. This delay in reaction time further contributes to the inability to stop instantly. Accelerating: 1. Inertia: Similar to stopping, inertia plays a role in accelerating as well. When you try to accelerate, you need to overcome the inertia of your body and the objects around you. This requires force and time.2. Power limitations: Accelerating requires the application of force, which is limited by the power output of the engine or the muscles involved. Generating a large amount of force instantly is often not possible due to these limitations.3. Safety considerations: In many situations, accelerating instantly can be dangerous. It can cause sudden changes in velocity, leading to loss of control or accidents. Therefore, safety considerations often dictate that acceleration should be gradual rather than instant. In summary, the inability to instantly stop or instantly accelerate is primarily due to factors such as inertia, friction, reaction time, power limitations, and safety considerations. These factors require time and force to overcome, making instant changes in motion impractical or unsafe.
