AQA AS Physics - Mechanics and Materials Exam Questions and Answers 100% Pass Scalar A unit with magnitude but no direction. Vector A unit with magnitude and direction. What are the two methods for adding vectors? Scale drawings and trigonometry. Free-body force diagrams Show all the forces acting on a body, each arrow shows the size and the direction of the force. Equilibrium The forces acting on a body are balances and it is not accelerating (it may be at rest or at a...

physics regents Question and answers already passed physics regents What is the difference between a vector and a scalar? - correct answer Vectors need both direction and magnitude (velocity, force etc.) while scalars only need magnitude (volume, time, area etc.) What is the one acceleration equation NOT on the reference tables? - correct answer d=1/2(Vi+Vf) t If a mosquito hits a truck, are their forces equal? - correct answer Forces are equal, but energy of the truck overcomes ...
