Kinematics in One Dimension

Question 1

Displacement

Answer 1

A vector that points from an object’s initial position to its final position and has a magnitude that equals the shortest distance (m)

Question 2

Is speed a scalar or vector?

Answer 2

Scalar

Question 3

Is velocity a scalar or vector?

Answer 3

vector

Question 4

Average speed

Answer 4

speed = distance / time

Question 5

Average Velocity

Answer 5

V = (X-Xo) / (t-to)

Question 6

Is acceleration a scalar or vector?

Answer 6

Vector

Question 7

What is acceleration?

Answer 7

Acceleration is the time rate of change of velocity

a = (V-Vo) / (t-to)

Question 8

Equation 1

Answer 8

V = Vot + at

Question 9

Equation 2

Answer 9

X = 1/2(V+Vo)t

Question 10

Equation 3

Answer 10

X = Vot + 1/2a(t-squared)

Question 11

Equation 4

Answer 11

(V-squared) = (Vo-squared) + 2ax
