because it have sound energy
The passengers fall forward when the driver applies brakes suddenly because of inertia. Inertia is the tendency of an object to resist changes in its state of motion. When the bus abruptly decelerates, the passengers continue moving forward due to their inertia, causing them to fall forward.
The law of inertia, as formulated by Newton's first law of motion, applies in this situation. According to this law, an object in motion will continue in motion unless acted upon by an external force. When the brakes are suddenly pressed, the bus decelerates but the person's body tends to resist this change in motion, causing them to be thrown forward.
'The car's inertia carried it forward several feet after the driver pushed the brakes.' 'His inertia launched him forward after reaching the base of the hill.'
If the driver suddenly slams on the brakes and comes to a sudden stop, passengers may be jolted forward, potentially causing injuries or falls. It is important to hold on to the handrails or seat in front of you to brace for sudden stops and ensure safety.
In an energy conversion that is 100% efficient, all of the available energy is converted to another form without any losses. In reality no energy conversion is 100% efficient. An example of this is using the brakes to stop a bike. Not all of the energy that you exert on the brake levers goes into stopping the bike. Losses occur including heating of the brakes and noise (when they squeal). Efficiency is a measure of how much useful energy can be converted from one form to another, and when calculated is more often than not expressed as a percentage.
Yes, they make a screeching sound.
If you hear screeching bike brakes while riding, you should gently apply both brakes to slow down and come to a controlled stop. Check your surroundings for any potential hazards and assess the condition of your brakes before continuing your ride.
The driver suddenly applied the brakes.
The friction between the road and the tires creates and screeching sound.
Sounds like the pads are shot. Take a wheel off and check.
Those cars do not have ABS brakes. If they had they wouldn't screech.
Your bike brakes may be screeching due to dirt or debris on the brake pads or rims, misalignment of the brake pads, or worn brake pads. To fix this, you can clean the brake pads and rims, adjust the alignment of the brake pads, or replace the brake pads if they are worn out.
When motorcycle brakes lock, they make a light grinding sound accompanied by the loud screeching of the tires. When the brakes lock, the tires are forced to slide along the pavement until the brakes are released on the bike stops.
Brakes turn kinetic energy into heat.
