Speed
In a car, the speedometer measured Instantaneous speed. This comes from the assumption that the car does not slow down and speed up fast enough for the speedometer to be able to give an average of the changing speed.
To match a constant speed engine with a variable speed vehicle.
Acceleration
Acceleration
The cross sectional area of a car is dependent on its height. As the area changes the drag on the car, it is likely that increasing the height of a car will also reduce its top speed. There are many other factors that affect a car's maximum speed so a change in height may not always result in a change in top speed.
Yes, acceleration directly impacts the change in speed of a car. A higher acceleration will cause the car to increase its speed more rapidly, while a lower acceleration will result in a slower increase in speed.
If you divide the distance travelled by the speed, you'll get the speed in meter/second. If you prefer to have the speed in kilometers/hour, multiply this first result by 3.6.
When a car accelerates, its velocity increases over time. This change in velocity is the result of a force being applied to the car, which causes it to speed up.
This may have been the result of steering the car around a curve in the road while maintaining constant speed.
True, the force of impact in a collision increases significantly with speed. This is because kinetic energy, which relates to an object's speed, increases with the square of the speed. So, tripling the speed of a car would result in nine times the force of impact in a collision.
The size of the tyre affects top speed by altering the gearing. Assuming the engine has the power, a larger size wheel and tyre (diameter) will result in higher top speed.
The speed of the car.
two things cause a car to slow down friction from the wheels and drag from the air. cars experience resistance from the air (drag) and this resistance increases as the speed of the air/car increases. As a result the more fuel is needed to keep the car going at a higher constant speed (you have to press harder on the gas pedal at that speed).
Yes, the height of a ramp will impact a toy car's speed going down it. A steeper ramp will generally result in a faster descent due to the increased gravitational pull. Conversely, a lower ramp will lead to a slower speed as there is less gravitational force acting on the car.
Both the speed and velocity have increased as a result of acceleration.
When a car is moving at a certain speed, objects in the car, including people, move at the same speed as well. When a car accident happens, for example the car crashes into a wall, the car stops moving suddenly because of the obstacle it hits. The people, however, don't meet the obstacle and keep on moving at the same speed they had been moving before the accident. As a result, these people usually hit the front car glass or the steering wheel and get injured.
