acceleration
Acceleration is the rate of change of speed with respect to time during a given interval.
Acceleration is an increase in speed during a given interval of time. It is the rate of change of velocity with respect to time.
Acceleration is an increase in speed during a given interval of time. It measures how quickly an object's velocity is changing. Acceleration can be positive (speeding up), negative (slowing down), or zero (constant speed).
positive acceleration
false
Actually, an increase in speed during a given interval of time is called acceleration, not negative acceleration. Negative acceleration, also known as deceleration, refers to a decrease in speed over time.
(change in distance) divided by (time interval) = the object's average speed during that time interval.
No, it's only the acceleration. By (-)ve acceleration ,it means retardation or deceleration..

As speed increases, the frequency content of the digital signal increases. This means that the rate at which individual cycles of the signal occur within a given time interval will increase. Additionally, the bandwidth required to transmit the digital signal also increases to accommodate the higher frequencies present.
Speed
No. It is the change in velocity (not speed) during a given interval of time. It can be an increase or a decrease although a decrease is also called a deceleration.The distinction between velocity and speed can best be illustrated by an object going round in a circle at a constant speed. It is changing direction all the time so that its velocity is constantly changing. It is constantly accelerating even though it is travelling at constant speed.
