What is the common object used in all scenarios to move the boxes?

• A wheel

• A rope

• A pulley

• A lever

Which force acts on all objects at all times?

• Gravitational force

• Electromagnetic force

• Magnetic force

• Nuclear force

In which direction does frictional force act when the box is pulled to the right?

• Downwards

• To the left

• Upwards

• To the right

What effect do wheels have on the frictional force between the box and the floor?

• No effect

• Reduce friction

• Increase friction

• Double the friction

What is the role of oil when applied at the bottom of the box?

• Prevents movement

• Makes the surface rougher

• Acts as a lubricant

• Increases friction

How does oil on the rope affect the ability to grip it?

• Has no effect

• Makes it easier to grip

• Makes it harder to grip

• Increases the rope's strength

Which scenario is identified as the most difficult for moving the box?

• Using a rope rubbed with oil

• Using a rope with wheels

• Using a rope with oil at the bottom of the box

• Using only a rope

What is the primary factor that makes it difficult to pull the box?

• Gravitational force

• Frictional force

• Magnetic force

• Air resistance
