Reflect and research
- It was once believed that there was an absolute reference frame called the “luminiferous aether”. What was the name of the experiment that disproved the existence of this frame of reference?
- Find the centripetal acceleration of the Earth around the Sun.
To try at home
- Describe and carry out a small experiment to confirm that the amount of time that it takes for a projectile to fall a certain distance does not depend on the horizontal component of its velocity.
To try in the lab
- Develop a proposal for measuring how fast you can throw a ball, and carry out the experiment.
- Develop a proposal for measuring how far you can jump with a running start (e.g. a long jump).
- Propose an experiment to determine the period of the sun’s rotational motion.
