Constant acceleration equations

Question 1

What is ‘u’

Answer 1

initial velocity (m/s)

Question 2

What is ‘v’

Answer 2

final velocity (m/s)

Question 3

What is ‘a’

Answer 3

acceleration (m/s^2)

Question 4

What is ‘t’

Answer 4

time interval in seconds

Question 5

What is ‘s’

Answer 5

displacement (m)

Question 5

Explain a=v-u
____
t

Answer 5

acceleration is the final velocity minus the initial velocity over the time passed

Question 6

Explain v=u+at

Answer 6

final velocity is equal to the initial velocity + acceleration*time passed

Question 7

Explain s=1/2(u+v)t

Answer 7

displacement is half of (initial velocity plus final velocity) x time

Question 8

Explain s= ut+1/2at^2

Answer 8

displacement is initial velocity * time + 1/2accelerationtime squared

Question 9

Explain s= vt-1/2at^2

Answer 9

displacement is final velocity * time - 1/2accelerationtime squared

Question 10

Explain v^2=u^2+2as

Answer 10

final velocity squared is the initial velocity squared + 2accelerationdisplacement

Question 11

Can these equations be used if acceleration isn’t constant?

Answer 11

No
