CP1c Acceleration

Question 1

Acceleration (definition)

Answer 1

Acceleration is a change in velocity

Question 2

Acceleration (unit)

Answer 2

m/s2 (metres per second squared)

Question 3

Acceleration (calculation)

Answer 3

acceleration = change in velocity/ time taken
a = v-u/ t
acceleration = final velocity - initial velocity/ time

Question 4

Deceleration

Answer 4

When an acceleration causes an object to go slower. Acceleration will have a negative value. (REMEMBER: ONLY USE NEGATIVES IF THE QUESTION ASKS FOR THE ACCELERATION OF AN OBJECT - NOT THE DECELERATION)

Question 5

Acceleration (calculation) including distance

Answer 5

(final velocity)2 - (initial velocity)2 = 2 x acceleration x distance
V2-U2 = 2 x a x X

Question 6

acceleration due to gravity (g)

Answer 6

10 m/s2
