Forces and Motion

Kepler's Laws

Aimed at pupils aged 14-18, this activity will focus on investigating Kepler's three laws of planetary motion, with a particular emphasis on Kepler's Third Law: The Law of Periods, which explains the relationship between the distance from an orbiting body to a system's centre of mass and its period of orbit.

Pupils 16-18 / more able students: The relationship will also be put to the test by calculating the mass of the host star of the stellar system TRAPPIST-1 using the known orbital periods of its exoplanets. 

Hunting For Asteroids

Aimed at pupils aged 11-14 this workshop encourages pupils to ‘blink’ between several images, taken by the Liverpool Telescope, in a bid to find asteroids. The activity can then be extended to them using the LT Image software functionality to calculate the speed of the asteroids, or simply a discussion on what asteroids are and how we track them.

If something is moving, it will keep going in the same direction, and at the same speed unless it is changed by a force, such as someone pushing or pulling it.

This is called momentum
