-- The driver of the car says that the speed of the fly is zero.
-- An on-looker sitting on a park bench as the car passes him says that the speed
of the fly is 80 kph.
-- Both are correct, since there's no such thing as the "real speed", and speed is
always referred to something.
The fly is motionless, compared to your shoulder or the rear-view mirror. The fly is traveling at 80 km/hr with reference to the street signs on the side of the road. Assuming that traffic is going 80 km/hr each way, the fly is traveling at 160 km/hr with respect to the oncoming traffic in the other lane.
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.
If the car pulls onto the truck while maintaining a speed of 65mph, and the truck is moving at 60mph, the car's overall speed will be 65mph. The car's speed does not change by being on the truck, it merely matches the truck's speed.
The slope of a surface can affect a car's speed by influencing the force of gravity acting on the car. Going uphill will slow the car down as gravity works against the car's forward motion, while going downhill will speed the car up as gravity provides additional force in the direction of motion. Overall, steeper slopes will have a greater impact on the car's speed than gentle slopes.
The kinetic energy of an object is directly proportional to its mass and speed. Since the truck has a greater mass than the car but they are traveling at the same speed, the truck will have more kinetic energy than the car.

It matters how fast the car is going!
a car going by
100kmh
The speed of an car per hour[s] is the speed that the car is going.Example- If a car is going 75 miles for5 hours,what is the cars speed.The car speed is 75 miles per hour.
This question makes no sense, what do you mean? the speed of the car does not dictate the posted speed limit.

No, Some cars don't come with head rests.
If a racehorse and car are going 50mph they would both be going the same speed.
If the car pulls onto the truck while maintaining a speed of 65mph, and the truck is moving at 60mph, the car's overall speed will be 65mph. The car's speed does not change by being on the truck, it merely matches the truck's speed.
you have a car match your speed, then you look at your speed guage :P
