What is mechanical advantage?
A measure of how much a tool strengthens a force
A measure of speed
A measure of distance
A measure of time
What is the function of an axle in a wheel?
It provides decoration.
It allows the wheel to turn.
It increases the weight of the wheel.
It stops the wheel from moving.
What is required for a pulley to do work?
A magnet
A rope, chain, or belt
A battery
A spring
What happens when more pulleys are added to a system?
The work requires more force
The work requires less force
The work becomes impossible
The work requires the same force
What is an inclined plane?
A flat surface that is higher on one end
A curved surface used for decoration
A flat surface that is lower on one end
A vertical surface used for climbing
How do inclined planes make work easier?
By increasing the distance over which a force is applied
By decreasing the distance over which a force is applied
By increasing the force needed to move an object
By making the surface slippery
What is the primary use of wedges?
To lift objects
To split things (separate two objects)
To measure angles
To create friction
What effect does the wide end of a wedge have?
It reduces force at the small tip
It creates greater force at the small tip
It balances the force equally
It eliminates force at the small tip
What is a screw?
A flat surface
A lever
An inclined plane wrapped around a shaft or cylinder
A pulley
What happens when the path of a screw is longer?
More force is required
Less force is required
The screw does not move
The screw becomes a lever
