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.


Momentum using a Newton's Cradle

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
