What is a Force. Def. - . cause physical change. Ex – Friction and gravity . Forces are measured in . Newtons. , N . Mass. Def. – How much matter an object has. Ex. – Weight . Free body diagrams . show the magnitude and direction of ALL of the forces acting on an object. . Generally we represent the object as a box with the force arrows coming out from the centre, in the direction they are acting.. (Forces , Motion and Energy) . Biographical Info About Newton: . Lived from 1642-1727 in England . Published first detailed mathematical model in physics . Discovered the spectrum of light . First to propose that light is composed of particles .

Static Equilibrium: We can use this fact to find the conditions for "static equilibrium": the condition an object is in when there are forces acting on it, but it is not moving. . The conditions for static equilibrium are easy to state: the sum of the (vector) forces must equal zero, and the sum of the torques must equal zero: . Bellringer 10/7 An astronaut with a mass of 85 kg is outside a space capsule when the tether line breaks. To return to the capsule, the astronaut throws a 2.0kg wrench away from the capsule at a speed of 14m/s. At what speed does the astronaut move toward Forces and Motion Chapters 11-12 Frame of reference A system of objects that are not moving with respect to one another To describe motion accurately and completely, a frame of reference is necessary.
