Discover the dual nature of friction - a force that resists movement but is also essential for control. Understand its effects on surfaces, heat generation, and Newton's Third Law. Experience a simulation at an atomic level and solve anagrams related to teen activities.

Friction – A force which resists movement Can you think of two effects of Friction? • Solve the anagrams… • TEENAGERS heat • wears away FUSESCAR Generates heat Wears away surfaces Friction – A force which resists movement, but is also really useful to control movement too. Think of trying to move on ice…
