The force resisting the motion of the car and the trailer are 400 N and 100 N respectively.  \n(i) Determine the forward thrust applied to the car.  \n(ii) What is the magnitude of the tension in the bar between the car and the trailer?  \nSolution  \n(i) The sum of the forces in the horizontal direction must be zero because the car is in a constant motion. Therefore, if the resistance forces sum to 500 N the forward thrust of the car must be 500 N.  \n(ii) The trailer is pulling on the car with a force of 100 N, and the trailer is moving at constant velocity therefore the car must be pulling on the trailer with a force of 100 N. Thus the tension in the bar connecting the two is 100 N.  \nGRAPHS  \nPosition-Time Graph: A point at a certain time gives position and the gradient gives the velocity.  \nVelocity-Time Graph: Area under the curve gives the displacement, a point on the curve gives the velocity and the gradient of the curve gives the acceleration.  \nAcceleration-Time Graphs: The velocity is the area under the graph.  \n© the school [for](for excellence 2013 free online resources at www.tsfx.com.au)[ excellence](for excellence 2013 free online resources at www.tsfx.com.au)[ 2013](for excellence 2013 free online resources at www.tsfx.com.au)[ free](for excellence 2013 free online resources at www.tsfx.com.au)[ online resources at](for excellence 2013 free online resources at www.tsfx.com.au)[ www.tsfx.com.au](for excellence 2013 free online resources at www.tsfx.com.au)  \nNEWTON’S LAWS OF MOTION  \nAccording to Newton, Space, time and mass are absolute, remain same for any observer.  \n1. Inertia: The velocity of an object will remain constant unless a net force acts on the object. Constant velocity = no acceleration = net force 0  \n2. Force is equal to the change in momentum per change in time. For a constant mass, F=ma.  \n3. For every action, there is an equal and opposite reaction. Two forces: always exist in pairs – are equal in magnitude – act in opposite directions – act on separate objects!  \nEXAMPLE  \nBook sitting on a table not action/reaction pair. Earth is pulling the book and table pushing the book (forces on same object) . Pair: Earth pulls book and book pulls earth.  \nTYPES OF FORCES:  \nNormal Reaction: The upward push of the surface on an object.  \nWeight: The down push of an object on a surface.  \nDriving Force: The forward push of an object; much like thrust except driving force is used for vehicles.  \nResistance Forces: Any force that acts in opposition to motion.  \nINCLINED PLANES  \nPROJECTILE MOTION  \nHorizontal component: V 􀀠 U 􀀠 V cos􀁔 a 􀀠 0 s 􀀠 ut  \nVertical component: a 􀀠􀀐 10 u 􀀠 Vsin􀁔 s 􀀠 displacement  \nAir resistance: Always opposes motion, magnitude of resistance increases as projectile increases.  \n􀂚 Time always the same for both.  \n􀂚 Draw velocity vectors for components.  \nCIRCULAR MOTION  \nVelocity is always in direction at a tangent at given point. Centripetal Force (=Net force) and acceleration always towards the centre. If the speed is constant in circular motion then there must be acceleration.

Leaning into a curve increases the size of the centripetal force, allowing for a higher speed when cornering. A component of the normal reaction acts towards the centre, thus increasing the net force.  \ntan 􀁔 􀀠 v2 / gr g 􀀠 gravity r 􀀠 radius v 􀀠 velocity  \n© the school [for](for excellence 2013 free online resources at www.tsfx.com.au)[ excellence](for excellence 2013 free online resources at www.tsfx.com.au)[ 2013](for excellence 2013 free online resources at www.tsfx.com.au)[ free](for excellence 2013 free online resources at www.tsfx.com.au)[ online resources at](for excellence 2013 free online resources at www.tsfx.com.au)[ www.tsfx.com.au](f","cbCaijnwt3n720UV","https://ap.wps.com/l/cbCaijnwt3n720UV","pdf",816488,11,"English","# Motion\n## Constant velocity example\n## Motion graphs\n## Newton’s laws of motion\n# Forces and applications\n## Types of forces\n## Inclined planes, projectile motion\n## Circular motion and banked curves\n## Apparent weight in vertical motion\n# Momentum and work\n## Momentum and impulse\n## Conservation of momentum\n## Work and kinetic energy","[{\"question\":\"How do you determine thrust and tension when a car tows a trailer at constant speed?\",\"answer\":\"For constant motion, the horizontal net force is zero, so the forward thrust equals the sum of resistance forces.
