INCLINED PLANES TEST EXAM QUESTIONS AND ANSWERS

Simple Machine Device that makes work easier, often by reducing the amount of effort force needed to move an object Inclined Plane A ramp or slope that reduces the force needed to move objects up and down heights; a simple machine Force A push or pull that can change the motion of an object, measured with a spring scale in Newton (N) units Spring Scale A tool that measures a pulling force by the tension on a spring; the force is measured in Newtons Newton Unit of force. Inclined Plane A simple machine that is sometimes called a ramp which decreases the amount of force needed to move a load from one place to another. Flat surface that slopes. The steeper ramp. The angle (the steepness of the inclined plane) determines how much effort is needed to raise the weight. The steeper the ramp, the more effort is required. Which inclined plane requires the most effort, a steeper ramp or a longer less steep ramp? The longer ramp. The angle (the steepness of the inclined plane) determines how much effort is needed to raise the weight. The steeper the ramp, the more effort is required. Which inclined plane requires the least effort, a steeper ramp or a longer less steep ramp? The longest one. It takes less force to move it up the ramp. You have three ramps of the same height but different lengths...short, medium and long. Which one requires the least amount of force to lift an object to the top? Why?
