Motion In One Direction

Question 1

Instantaneous Velocity

Answer 1

The velocity given at a specific instant/time

Question 2

Displacement

Answer 2

The change in position of an object

Question 3

Average Speed

Answer 3

The overall rate of motion over a time interval; the total distance travelled by an object over that time interval

Question 4

Average Velocity

Answer 4

The displacement of the object divided by the time interval taken to travel the displacement.

Question 5

Average Acceleration

Answer 5

Change in velocity of the time interval divided by the time interval change that is taken place.

Question 6

How do Velocity and Acceleration relate to how fast an object is moving?

Answer 6

If the directions of velocity and acceleration are the same, they are speeding up.

If they are opposite, they are slowing down.

Question 7

Unit Vector

Answer 7

Magnitude one and no units.

Question 8

Displacement Vector

Answer 8

Change in position vector of object

Question 9

Constant Speed Equations

Answer 9

d = vt
d = xf - xo

Question 10

Constant Acceleration Equations

Answer 10

xf = xo + vt
vf = vo + at
d = vot + 1/2at^2
xf = xo + vot + 1/2at^2
