speed

Question 1

what is the difference between speed and velocity?

Answer 1

speed - change of distance per unit time - scalar

velocity - change of displacement per unit time - speed in a given direction

Question 2

What does constant velocity mean?

Answer 2

object moves at the same speed without changing direction

Question 3

What is acceleration?

Answer 3

change of velocity per uit time

m s-2

Question 4

What is the velocity equation?

Answer 4

(v-u) / t

Question 5

How can acceleration be determined from a velocity time graph?

Answer 5

it is the gradient

Question 6

What is the equation for displacement and average velocity?

Answer 6

s = ( u + v )t / 2

Question 7

What is the equation for s w/o v?

Answer 7

s = ut + 1/2at2

Question 8

what is the equation for V w/o t?

Answer 8

v2 = u2 + 2as

Question 9

What does displacement = in a velocity time graph?

Answer 9

area under the line
