Welcome to the GCSE Physics Ninja **Length, Time & Motion **course.

These video lessons are based on question-and-answer flashcards. You can either make your own or purchase the printable flashcards from the **shop**.

When you have completed this course, you will be able to...

- Become familiar with the quantities and units used to
**measure length, time**and**motion**. - Measure
**short time intervals**with reasonable accuracy. - Use a
**micrometer screw gauge**to measure very small lengths. - Measure and calculate the
**density**of a substance. - Understand how to interpret
**distance-time graphs**and**velocity-time graphs**. - Calculate
**distance travelled, speed and acceleration**of an object using a graph, or an equation. - Explain how objects can move in
**circular motion**. - Perform calculations on
**simple pendulums**. - Understand what
**vectors**are, and how to find a resultant vector graphically.
