A pulley can be seen in the Gym. A pulley can be seen on the well - which is used to draw water. A pulley can sometimes be seen on the elevator, which is used to pull the car.
A fixed pulley can be used for certain reasons as for making things easier.
a flag pole is a pulley
which pulley changes the direction of force
yes
The matched subject because the experiment involves pairs which halves the df.
Used when you have an experiment with several related dependent measures. Also used to analyze data from a within subject design.

Rope and pulley.
A Pulley is basically a kind of lever that can be used to change the direction of a force. Properly used, a pulley or system of pulleys can multiply forces

I used a pulley to lift the large log.
To make a pulley project for fourth grade, you can use a simple setup with a pulley, rope, and a small lightweight object to lift. You can demonstrate how the pulley makes it easier to lift the object by distributing the force needed over multiple ropes. Have the students experiment with different numbers of pulleys and ropes to observe the differences in lifting efficiency. Encourage them to think about real-life applications where pulleys are used, such as in elevators or construction sites.
