### 100

Efficiency and a comparison of mechanical advantage and ideal mechanical advantage gives you an idea of this.
What is how much energy is lost due to friction in a machine?

### 100

A simple machine consisting of a bar that rotates around a fixed point called a fulcrum is this.
What is a lever?

### 100

The number of times a machine multiplies input force is known as this.

### 100

This is the rate at which work is done.
What is power?

### 200

A type of lever there the fulcrum is located on the far side of the input force area, has an ideal mechanical advantage less than 1, and does not result in a change in the direction of force is this.
What is a third class lever?

### 200

This is the SI unit for power.
What is Watt?

### 200

A simple machine that consists of two connected rings or cylinders, one inside the other, which both turn in the same direction around a single center point is this.
What is a wheel and axle?

### 200

The SI unit for work is this.
What is Joule?

### 200

When the force is applied to the wheel of a wheel and axle machine, the axle has this amount of output force relative to the input force.
What is more?

### 300

A type of lever where the fulcrum is between the input and output force areas, and results in a change in the direction of the force is this.
What is a first class lever?

### 300

Compound machines tend to have a lower efficiency than simple machines due to this.
What is friction?

### 300

This is a device that makes work easier by changing a force.
What is a machine?

### 300

This value associated with a compound machine is the product of all the simple machines incorporated into the compound machine.

### 300

When the force is applied to the axle of a wheel and axle machine, the wheel has this amount of output force relative to the input force.
What is less?

### 400

This is the use of force to move an object.
