Inclined Planes

What is a flat surface tilted at an angle, also known as a ramp?

• Inclined plane

• Wheelchair

• Staircase

• Screw

How does an inclined plane make work easier?

• By reducing the distance the load travels

• By increasing the effort needed to move a load

• By reducing the effort needed to move a load

• By increasing the distance the load travels

Where are inclined planes often used for moving heavy loads?

• In multi-story car parks

• In swimming pools

• In playgrounds

• In libraries

What makes staircases work similarly to ramps?

• Their material

• Their shape

• Their color

• Their function

What is another example of an inclined plane in a special winding pattern around a cylindrical shaft?

• Wheel

• Screw

• Lever

• Pulley

What happens when a screw is turned into material like wood or metal?

• It doesn't affect the force needed to drive it in

• It breaks the material

• It reduces the force needed to drive it in

• It increases the force needed to drive it in

Where are screws commonly used for connecting materials strongly and stably?

• In painting

• In building furniture

• In gardening

• In cooking

What is the purpose of a ramp?

• To reduce the effort needed to move a load

• To make work easier

• To make work harder

• To increase the distance the load travels

What is the purpose of a staircase?

• To make work harder

• To reduce the effort needed to move a load

• To increase the distance the load travels

• To allow movement to higher or lower positions more easily

What is the purpose of a screw?

• To reduce the force needed to drive it in

• To increase the distance the load travels

• To make work harder

• To reduce the effort needed to move a load
