Yes, an average speed is only the difference between the highest and lowest speeds over a specified length of time. If an object accelerates from a standing start, accelerates to 10 metres per second over ten seconds and then slows to a stop at the same rate, the average speed would be 5 m/s. It is more difficult to calculate an accurate average speed when travelling at varying speeds.
Of course.
The instantaneous can be less than the average:
Your average speed from your home to your job is probably somewhere between
5 and 40 miles per hour. Your instantaneous speed when you're stopped at red light
along the way is zero.
The instantaneous can be more than the average:
If you have to drive home in a blizzard, or during rush hour on the LA Freeway, you
may have to crawl bumper to bumper for an hour, and your average speed for the
trip may be only 5 miles per hour. But your instantaneous speed as you enter the
freeway, or when you finally reach the street where you live, may be 10 miles per hour.
Yes. For example, a vehicle that travels 25 mph for an hour and then 75 mph for an hour has an average speed of 50 mph though it spent half that time traveling much faster.
yes
Yes.
No. No object can move faster then light. However, Minato Namikaze (the Fourth Hokage) and Uchiha Madara posses the ability to move at speed nearing the speed or light, or the speed of light itself, utilizing the space-time ninjutsu.
True . A+
true
Force = Mass * Acceleration or Acceleration = Force / MassThe Mass is the mass of the object and the Acceleration is the change of speed of the object due to the Force.
gravity
yes depending how much you applied
stays the same
An object can move in a circle at different speeds.
Temperature IS the average speed of movement of the particles molecules that make up an object. The more heat you add to an object, the faster the molecules move vibrate. There are devices thermometers that indirectly measure this speed, and thus report the temperature.

The slowest speed an object can move is zero.
Most things don't move with the same speed at all times
5m/s
Yes,because if a force is getting weaker it causes the speed to slow down but if the force is getting stronger it causes the object to move faster.
