A worksheet packed with questions to suit all abilities on the subject of motion and balanced and unbalanced forces. From simple force diagrams to terminal velocity and maximum speed of cars, this is the ideal resource to consolidate student knowledge and test understanding of these key concepts. Aimed at ks3 students or year 11 students, it serves as a qualitative introduction to resultant forces and their effect on the motion of everyday, and some not everyday, objects. Challenging extension tasks are provided for more able students. Enjoy. A Science Geeks video included too!

A video plus a worksheet all about stopping distances, braking distances and thinking distances! Questions start off simply until they ultimately challenge high ability students to discover the square relationship between velocity and braking distance! There is also an accompanying 2 minute Science Geeks YouTube video available that provides students (and teachers) with all the basic knowledge they need to know. All images, photos and graphics are made or taken by M.E.Prince (that's me!). No copyright issues.

Brain busting training to get your students exam ready and fit to go.

Students move around a circus of simple investigations and answer questions at each station (simple technicians list provided)! The encounter lots of different forces and see them in action and try to understand if the forces are contact forces or forces acting at a distance. Magnetic forces, gravity, electrostatic forces, pushes and pulls and Buoyancy! Oh what fun we had! The worksheet for the activity is accompanied by a complete answer sheet to save you, my wonderful colleagues, valuable time. Word files and pdfs supplied so that you can edit or modify too!
