Push- Pull : Year 2 Physical Sciences
Forces are at work in everything we do -- we push to open doors, and pull to tie ropes. Gravity pulls on things to make them fall down or to keep them down. Scientists and engineers study forces to design better bridges and faster aeroplanes, and to reduce the forces that impact on people in car accidents.
