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.
If the car is going at a constant speed of 100 km/h, then its acceleration is zero. Acceleration measures the rate of change of velocity, and since the car's speed is not increasing or decreasing, there is no acceleration.
A stopped car has a speed of 0 m/s because it is not moving. Speed is the rate at which an object changes its position, so if the car is not changing its position, its speed is 0.
No, the force of impact is not directly proportional to the speed of the car. In a collision, the force of impact is determined by the change in momentum, which is a combination of speed and mass. Doubling the speed does not necessarily mean quadrupling the force of impact.
Acceleration is the term used to describe a car increasing in speed. It refers to the rate of change of velocity with respect to time.

What part of an automobile's engine has a direct impact on the acceleration rate of the vehicle as well as what do I do to improve that vehicles acceleration rate.
Speed descibes the rate of motion of an object. Velocity describes rate of motion (speed) of an objectin a specific direction. For example - the car's speed was 60mph, the car's velocity was west at 60mph.
If the car is going at a constant speed of 100 km/h, then its acceleration is zero. Acceleration measures the rate of change of velocity, and since the car's speed is not increasing or decreasing, there is no acceleration.
It depends on the rate of speed the car is travelling.
A stopped car has a speed of 0 m/s because it is not moving. Speed is the rate at which an object changes its position, so if the car is not changing its position, its speed is 0.
If you triple the speed of your car, the kinetic energy increases by a factor of nine, as kinetic energy is proportional to the square of the speed. This means that stopping distances will also increase significantly, making it much harder to stop safely. Additionally, the risk of accidents rises due to reduced reaction time and increased impact force in the event of a collision. Overall, driving at such high speeds poses serious safety hazards for both the driver and others on the road.

That depends on the speed of the impact.
The impact speed is just the difference between the two speeds, so in this case 2 km/hr.
the speed is a unit of measure used to describe the rate of movement. As in the car went 35 mph while it drove down the street.
