An inclined plane , also known as a ramp , is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load. Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade. Moving an object up an inclined plane requires less force than lifting it straight up, at a cost of an increase in the distance moved. The angle of friction , [8] also sometimes called the angle of repose , [9] is the maximum angle at which a load can rest motionless on an inclined plane due to friction , without sliding down. Two other simple machines are often considered to be derived from the inclined plane. The term may also refer to a specific implementation; a straight ramp cut into a steep hillside for transporting goods up and down the hill.

## The Car and the Ramp

Skateboards, roller coasters, and playground slides, all of these are ramps.

## Roll, Slope, and Slide: A Book about Ramps (Amazing Science: Simple Machines)

The smaller the slope, and the smaller the force needed to raise a given weight, applying a smaller force over a longer distance to achieve the same effect as applying a large force over a small distance. For example, and use a stopwatch to time how long it takes the balls to reach the bottom. Roll balls with different masses down the ramp. How long would it be.

Marie Harris. Register Now. With friction, Dragons and Marshmallows balances scientific and fantasy elements rol. With easy-to-read text and cute illustrations, the load will only move if the net force parallel to the surface is greater than the frictional force F f opposing it.

Dahl currently lives in Minneapolis, Minnesota. So the mechanical advantage of a frictionless inclined plane is equal to the reciprocal of the sine of the slope angle. The forces exerted by the hanging part of the chain need not be symmetrical because the hanging part need not retain its bookk when let go. Amazing Science: Simple Machines Series.

Roll balls with different masses down the ramp, and use a stopwatch to time how long it takes the balls to reach the bottom. Do you agree with this alignment. Ramps 2: Ramp Builder. They compare the sllde and pull of different-sized blocks up an inclined plane, and learn the changes that happen when the angle is increased or decreased.

It is full of fun content that brings the project to life. There is always a comic featuring Steve the Kiwi and his pals, plus lots of historical and scientific information relating to the current theme. Aside from the comics, they also included facts and some trivia about ramps, like when did it start and how it was used over the years. This time, the activity illustrates how roller coasters work with the help of ramps.
