Types of Simple Machines
A flat, slooped, surface, such as a ramp, is a simple machine called what?
What is an "incline"?
Many machines transfer mechanical energy from one "what" to another?
What is "object"?
The work a person does on a machine is called what?
What is the "input"?
Newton's laws of motion describe how "what" acts on objects?
What are "forces"?
A grooved wheel that has a rope or cable wrapped around it is called a "what"?
What is a "pulley"?
An inclined plane wrapped around a cylinder is called a what?
What is a "screw"?
A bottle opener transfers energy from a person's "what" to a "what"
What is "hand" and "bottle cap"?
The work the machine does on an object is called what?
What is the "output"?
Newton's third law describes how when you exert a force on a simple machine, such as using a hammer as a lever, the hammer exerts a "what" that is equal in size and opposite in direction on you?
What is a "force"?
A single pulley changes the direction of the input "what"?
What is the "force"?
A simple machine that pivots around a fixed point is called what?
What is a "lever"?
Machines that do work using one movement are called what?
What are "simple machines"?
A machine makes work easier by changing "what" about how the object moves?
What is the "distance"?
According to Newton's first law, the motion of an object changes when the forces that act on the object are "what"?
What is "unbalanced"?
What type of machine is made up of two or more simple machines working together?
What is a "complex machine"?
A shaft attached to a wheel of a larger diameter so that both rotate together is called what?
What is a "wheel and axle"?
Simple machines do not change the amount of work required to do a task; however they do change the way what is done?
What is "work"?
A machine make work easier by changing the amount of "what" required to do the work?
What is the "force"?
According to Newton's second law, the change in motion of an object is the same direction as the "what" force on the object?
What is the "net"?
Complex machines require more than one "what" to accomplish a task?
What is a "movement"?
