Acceleration is the rate of change of the velocity (speed) of an object. Acceleration is the derivative of the speed vs. time function.
The term? Velocity
The device? Radar
Temperature measures how fast molecules are moving or in scientific terms it measures the AVERAGE KINETIC ENERGY in a system. Temperature measures how fast molecules are moving. :):)
Average speed and instantaneous speed are both measurements of the speed of an object. The instantaneous speed measures how fast the object is going at a particular moment, while average speed shows how fast the object was moving in total over time.
speed How fast in which direction is velocity.
speed How fast in which direction is velocity.

Temperature is the measure of how fast particles are moving in an object.
This was the essential question on a homework assignment. Speed tells how fast an object is moving but it does not tell the direction. Velocity tells how fast an object is moving and it also tells the direction. When velocity is positive, the object is moving up. When velocity is negative, the object is moving down.
The surface area is the variable to determine how fast an object will be moving when it reaches terminal velocity.
