COLUMN A

COLUMN B

2.1

Displacement

2.2

Conservation of energy

C change in position from starting point to ending point in a straight line

2.5

Conductors

D allows electrons to pass through quite easily

E total path travelled

F position where two pulses meet out of phase

G energy cannot be created nor destroyed, it is merely converted from one form into another

QUESTION 3: TRUE OR FALSE

Indicate whether the following statements are TRUE or FALSE. Write only 'true' or 'false' next to the question number (3.1 - 3.5). Correct the statement if it is FALSE.

3.1

As a ball rolls down a uniform slope, the ball's successive displacement

increases in equal time intervals.

(2)

3.2

The acceleration of an object moving along a straight line can be determined

by calculating the area under a velocity versus time graph.

(2)

3.3

The speed of a pulse in a spring depends on the pulse length, tension in the

spring and the mass of the spring divided by the length of the spring.

(2)

3.4
