A basic device that can change the amount or the direction of force, or both at once is a ___________.
___________ results when a force produces a movement in the direction of the force.
A simple machine made up of a bar and a fulcrum is a ______________
A _____________ is made up of an inclined plane wrapped around a pole.
To raise a heavy load, you could use a system made up of one fixed ___________ and several moveable ones.
The part of a lever around which the bar moves is the_____________.
A large wheel connected to a smaller wheel is a ____________.
A flat surface that has one end higher than the other is a/an ______________.
In a lever, the force that is used to move the bar is called the:A. effort forceB. resulting forceC. fulcrumD. machine
When you push or pull a lever you put a force, called the ______________ on one side of the bar.A. resulting forceB. workC. effort forceD. efficiency
When you turn a doorknob, you are using:A. a wheel and axleB. a pulleyC. a fulcrumD. an inclined plane
A simple machine always:A. doubles lifting forceB. moves around a fixed pointC. moves an object in the same directionD. changes the size or direction of a force
When you use a lever to open a can of paint, the outer rim of the can is the:A. fulcrumB. resulting forceC. effort forceD. wedge
A fixed pulley is similar to a class one lever because it:A. changes the size of the effort forceB. changes the weight of the effort forceC. changes the position of its fulcrumD. changes the direction of the effort force
A wheel and axle increases the:A. resulting forceB. fulcrumC. effort forceD. friction
A wedge:A. reduces resulting forceB. decreases total workC. pushes things apartD. pulls objects
____________ is how well a machine changes effort into useful force.A. workB. efficiencyC. simple machineD. effort force
The main difference between a wedge and an inclined plane is how they are used
For a screw: the long ramp of the inclined plane is wrapped into a space that is a different height as the inclined plane but has almost no width.
A screw is like an inclined plane because it requires a longer movement but it makes a larger resulting force.
An inclined plane increases the amount of force needed to raise or lower an object to a given height.
A wheel and axle makes your effort force into a larger resulting force.
The top of the broom is the:A. effort forceB. fulcrumC. resulting forceD. simple machine
The bottom of the broom is the:A. effort forceB. resulting force C. simple machineD. fulcrum
The boys arm is the:A. effort forceB. resulting forceC. fulcrumD. simple machine
How is a seesaw an example of a definition of work?HINT: tell what happens on a seesaw that shows it is work
