How do you explain a car requires brakes in order to stop with law of motion?
The law of motion states that an object in motion stays in motion unless acted upon by an external force. In the case of a car, the brakes provide the necessary force to counteract the car's motion and bring it to a stop. Without brakes, the car would continue moving due to inertia.
If only external force can change the velocity of a body how can the internal force of the brakes bring a car to rest?
It is not the force of the brakes that is stopping the car but rather external force of friction between tires and the road. Notice that no matter what the force at the brakes is, the car won't stop if there is no friction there(ie. the road is slippery). This is an excellent question. Consider the NASA space shuttle. It has brakes, yet the brakes work only on the ground - only while the shuttle is landing. Why? In space, the brakes have nothing to react against. So, as the questioner suspects, the internal forces of the brakes alone are not sufficient to change the velocity of the space shuttle. But once the shuttle lands, and is rolling down the runway, applying the brakes creates friction between the wheels and the runway. And it is the external force of the runway pushing back against the braking wheels that causes the shuttle to slow down.
Everyday situation exhibit newton's first law of motion?
An everyday example of Newton's first law of motion is when a car comes to a stop without applying brakes. This happens because the car continues to move forward due to inertia until a force (friction or brakes) acts to stop its motion. Another example is when a ball rolling on a flat surface eventually stops due to the force of friction balancing its forward motion.
How can you tell if an object is accelerating?
You can tell if an object is accelerating if its speed is changing or if its direction of motion is changing. Acceleration is a vector quantity that includes both changes in speed and changes in direction.
What is the fastest accelerating road car?
Bugatti Veyron @ 0-60mph in 2.5 seconds
Why is my car accelerating to the right from a stop?
Your car may be accelerating to the right from a stop due to issues with the alignment, tire pressure, or a problem with the brakes on one side of the vehicle. It is recommended to have your car inspected by a professional mechanic to diagnose and fix the issue.
What force do the brakes use to stop a car?
the brakes use friction to stop the car
Which brakes are used more when stopping a car?
Foot brakes are used to stop a car. In an emergency however both the foot and hand brakes can be used to stop a car.
Is constant stopping and accelerating bad for a car?
It would be hard on the brakes and fuel mileage.
What causes a car to stop accelerating?
Lack of propulsion.
What force do Brakes use to stop objects?
Brakes use friction to stop a car.
What does the car breaks do?
The car breaks (brakes) stop the car.
How do you stop a hybrid car?
with the brakes.
Do you need brakes for a car?
If you want to stop you do.
How does a solar car stop?
brakes, or no sun
How do you use the hydraulic in the 2002 grand Maqruis?
To stop the car every time you use the brakes.To stop the car every time you use the brakes.
Is a car accelerating when it is coming to a stop at a light?
No, when anything is slowing down it is decelerating.
