Reuired Practicals

Question 1

Force and extension

Answer 1

Measure spring length before extension

Add 10 grams no bounce record length

Repeat add mass

Calculate extension- mass of extension minus starting mass

Question 2

Acceleration

Answer 2

Draw straight lines 20cm apart perpendicular to bench edge

Attach a car to string and bench pulley

Attach weight on pulley hold it so it doesn’t pull the car but is extended

Release and time car to hit pulley

Question 3

Waves
