Science

QuestionAnswer
What is an inclined plane? inclined plane is a sloping surface like a ramp, that reduces the amount of force required to lift an object.
How can you use less effort to load on an inclined plane? can be designed to reduce the force needed to lift a weight in 2 ways- increase the length of the ramp or decrease the height of the ramp. by increasing the distance of the effort force moves (length of the ramp) relative to the distance the weight is
What is a lever? simple machining consisting of a rigid rod or plunk that pivot, or rotates about the fulcrum.
What words do I need to know? Fulcrum- the support, or point of rest, on which a lever turns in a moving bod. load- what is being lifted. effort- extension of power, what you put into.
How does a lever help us use less force? A lever can be designed to reduce the amount of force required to lift a weight in 2 ways- by increasing the distance from the fulcrum to the point where the effort force is apptied or by decreasing the distance the weight is from the fulcrum.
What is a simple machine? a machine that does work with only one movement. six simple machines are- inclined plane, lever, wheel and axle, screw, wedge, and pulley.
What is a compound machine? a compound machine is a machine made up of a combination of simple machines and an bicycle in figure 8 is a familiar example of another compound machine.

What is an inclined plane? flat sloped surface and less force is needed to move an object from one height to another
What is a wedge? An inclined plane that moves.
What is a pulley? simple machine and changes the direction of effort.
