Physics quantities and
measuring techniques
For volume use measing
cylinder
Length use meter ruler
For time use stop clock or
stopwatch, analog or
digital(recommended)
Calculating average value of
distance
1. Measure distance multiple
times
2. Add results
3. Divide by n
A pendulum time period is
time taken to complete one
, oscillation
Scalar = magnitude only
Vector = direction and
magnitude e.g
1. Acceleration
,2. Velocity
3. Force
4. Displacement
5. Momentum
6. Weight
Resultant force is a single
force that has the effect of all
forces acting on an object
Velocity is the speed of
something in a given direction
of travel
Acceleration is a change in
Velocity
Acceleration = change in
Velocity over time taken
Deceleration is a decreasing
changing speed or negative
, Acceleration
Free fall is when an object
falls towards the Earth due to
gravity and is measured in g
and is
