Understanding the Effect of Surface on Force

The video tutorial explores how different surfaces affect the force needed to move a basket. Using a spring scale, the experiment measures the force in newtons required to move the basket across a table and a carpet. The results show that more force is needed on the carpet. The hypothesis that a softer surface like a rug requires more force is confirmed. The video concludes with an analysis of the data collected from multiple trials on both surfaces.

What tool is used to measure the force needed to move the basket?

• A ruler

• A spring scale

• A thermometer

• A stopwatch

What is the range of the spring scale used in the experiment?

• 0 to 5 newtons

• 0 to 15 newtons

• 0 to 20 newtons

• 0 to 10 newtons

How much force was required to move the basket across the table?

• 1.5 newtons

• 3 newtons

• 4 newtons

• 2 newtons

How many trials were conducted on the table surface?

• Four

• Three

• Two

• One

What was the force required to move the basket on the carpet?

• 5.5 newtons

• 3.5 newtons

• 2.5 newtons

• 4.5 newtons

How many trials were conducted on the carpet surface?

• Four

• Three

• One

• Two

What was the hypothesis regarding the force needed on different surfaces?

• The force would be the same on both surfaces.

• Less force would be needed on the rug.

• More force would be needed on the table.

• More force would be needed on the rug.

What was the recorded force for the table surface?

• 1.5 newtons

• 2.5 newtons

• 3.5 newtons

• 4.5 newtons

What conclusion was drawn about the force needed on different surfaces?

• Less force is needed on the rug.

• More force is needed on the rug.

• More force is needed on the table.

• The surface does not affect the force needed.

Why does the rug require more force to move the basket?

• Because the rug is harder.

• Because the rug is softer.

• Because the rug is smoother.

• Because the rug is longer.
