Topic 1: Measurement Part 1
1.What are systematic / random errors? How can they be eliminated?
Errors of measurement which result in all readings being consistent overestimates or underestimates of its true value.
Cannot be reduced by taking repeated readings.
Can be reduced or eliminated by careful experimental design or good experimental techniques.
Examples: apparatus (zero errors, poor calibration), poor experimental technique (consistent parallax error), external factors (air resistance, background radioactive count rate).
Small systematic errors mean good accuracy.
Errors of measurement which cause an unpredictable scatter of readings about a mean value.
Can be reduced by taking repeated readings and finding the average
Cannot be eliminated.
Examples: Inconsistent reaction time, random parallax error, environmental conditions (fluctuations in measurement), limited sensitivity of instruments.
Small random errors mean good precision.
Topic 1: Measurement Part 2
Distinguish between precision and accuracy.
A set of accurate readings is one where the readings are close to the actual value.
A set of precise readings is one that has a small spread or scatter of readings.
Topic 2: Kinematics Part 1
1. Define displacement, speed, velocity and acceleration.
Displacement – The linear / shortest distance in a given direction from a
Speed – The rate of change of distance.
Velocity – The rate of change of displacement.
Acceleration – The rate of change of velocity.
Topic 2: Kinematics Part 2
2. Derive the 4 kinematics equations which represent uniformly accelerated
motion in a straight line.
3. Describe qualitatively the motion of bodies falling in a uniform gravitational field with air resistance.
4. Explain why, for all real throws, the time taken to reach the maximum height must be shorter than the time taken to return to the starting point.

Water is pumped through a hosepipe at a rate of 90 kg per minute. It emerges from the hosepipe horizontally with a speed of 20 m s–1.
Which force is required from a person holding the hosepipe to prevent it moving backwards?
A 30 N
B 270 N
C 1800 N
D 10800 N
90 kg min-1 = 1.5 kg s-1
F = d(mv)/t
= v dm/t
= 30 N
