Physics Quiz 1

Question 1

Scalar and Vector

Answer 1

Scalar = magnitude (amount)
Vector = magnitude and direction

Question 2

N,E, Up and Right

Answer 2

usually Positive

Question 3

S,W, Down, Left

Answer 3

usually Negative

Question 4

Displacement Formula

Answer 4

D = X(final) - X(Initial)
Total Displacement = D(1)+D(2)+D(3)+….

Question 5

Speed Formula

Answer 5

speed (m/s) = d/t

Question 6

Velocity Formula

Answer 6

velocity (m/s) = displacement/time

Question 7

Distance Time Graph

Answer 7

Slope = Speed
Steep Slope = High Speed

Question 8

Speed Time Graph

Answer 8

Slope = zero, uniform motion, constant speed
Area = distance

Question 9

Acceleration Formula

Answer 9

1) acceleration (m/s2) = [Velo(final) - Velo(initial)] divided by time

2) acceleration = velocity/time

Question 10

Displacement Time Graph

Answer 10

slope is curved
- gives instanteous velo (velocity at a certain point)

Question 11

Velocity Time Graph

Answer 11

(Uniform = can be negative or positive)
Slope = Acceleration or Deceleration
Area = Displacement

Question 12

Acceleration Time Graph

Answer 12

Area = velocity of object
