Answer:

Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. ... Acceleration is defined as the change in the velocity vector in a time interval, divided by the time interval.

Answer:

Acceleration is the rate of change of velocity.

Explanation:

Acceleration= change in velocity/time (final velocity-initial velocity/time)

Acceleration is a vector quantity, this means it has both magnitude and direction.

SI unit: m/s2 (metres/second2)

EXAMPLE QUESTION

a car travelling at 70m/s slows down to 50m/s in 5 seconds. what is its acceleration?

ANSWER:

acceleration= change in velocity/time

50-70/5 because 50 is the final velocity and 70 is the initial velocity you have to minus them and divide them by 5 as 5 is the time.

50-70/5= -4

make sure to put the SI unit or your answer will be wrong

so the answer to this example question is -4m/s2

hopefully this helped
