A lever decreases the speed of an object.
Can you give an example of a lever?
A seesaw.
A bicycle.
A hammer.
A pulley.
What is a pulley used for?
To create friction for better grip.
To store energy for machines.
To lift heavy objects more easily.
To measure weight accurately.
How does a pulley make work easier?
A pulley only works in a vertical direction and cannot change force direction.
A pulley makes work easier by changing the direction of force and reducing the effort needed to lift heavy objects.
A pulley eliminates the need for any force when lifting objects.
A pulley increases the weight of the load being lifted.
What are wheels and axles used for?
Wheels and axles are used for decoration in vehicles.
Wheels and axles are used to enable movement and reduce friction in vehicles and machinery.
Wheels and axles are primarily used for storing energy.
Wheels and axles are used to increase weight in machinery.
Can you name a vehicle that uses wheels and axles?
Bicycle
Airplane
Skateboard
Train
What is the effort in a lever?
The effort in a lever is the weight of the lever itself.
The effort in a lever is the distance from the fulcrum to the load.
The effort in a lever is the force applied to lift or move a load.
The effort in a lever is the amount of friction present in the system.
What is the load in a lever?
The load in a lever is the pivot point around which it rotates.
The load in a lever is the distance from the fulcrum.
The load in a lever is the force applied to the lever arm.
The load in a lever is the weight or resistance being lifted.
How many types of levers are there?
5 types of levers
4 types of levers
3 types of levers
2 types of levers
What is the difference between a fixed and movable pulley?
A fixed pulley is used only for heavy loads, while a movable pulley is for lighter loads.
Both fixed and movable pulleys are used to lift loads in the same way.
A fixed pulley can move with the load while a movable pulley is stationary.
A fixed pulley is stationary while a movable pulley moves with the load.
