Physical Quantities and Measurment

1. Subtopic : 1.1 Grade: 10E Physics Mcgraw hill
Physical Quantities and
Measurement Techniques

2. 1. Describe the use of rulers to measure length and measuring cylinders to measure volume
2. Describe how to measure a variety of time intervals using clocks and digital timers.
3. Determine an average value for a small distance and for a short interval of time by measuring
multiples (including the period of oscillation of a pendulum).
4. Understand that a scalar quantity has magnitude (size) only and that a vector quantity has
magnitude and direction.
5. Know that the following quantities are scalars: distance, speed, time, mass, energy and
temperature.
6. Know that the following quantities are vectors: force, weight, velocity, acceleration,
momentum, electric field strength and gravitational field strength.
7. Determine, by calculation or graphically, the resultant of two vectors at right angles, limited
to forces or velocities only

7. To measure the thickness of a single sheet of paper, for example, measure the
thickness of the whole book, count the number of pages and then divide the total
thickness of the book by the number of pages to find the average thickness of
one sheet of paper.
How would you try to find the thickness of a
single sheet of paper?
