{{:forces:girl-motion-790x50.jpg|Forces & Motion Banner}} ====== Q7. Pushing Two Cars Up A Slope: ====== Pushing the car - The purpose of this task is to investigate forces acting on a car being pushed up a slope. ++++ Q7. CLICK HERE TO SEE / HIDE STUDENT FLIP RESOURCES:| This [[http://interactagram.com/physics/dynamics/MechanicalAdvantage/ramp/|slope simulation software]] shows that the same amount of force is required to raise an object up a slope, no matter whether the object is near the top or near the bottom of the slope. Also note that the force required to start an object moving is slightly more than the force required to keep it moving! **Use your mouse to click and pull down on the handle (hanging down from the pulley) and read the values from the [[http://en.wikipedia.org/wiki/Spring_scale|spring scale]].**

**Simulation: Force Required To Pull/Push Object Up A Ramp** Jack has to push a wheelbarrow up some steps. * How can Jack use half as much force to get his wheelbarrow to the top of the steps? * Explain your idea and why you think it will work. ---- ++++ ++++ Q7.
