Forces and Friction Quiz

Which force acts perpendicular to the slope in the force diagram?

• Tension

• Friction

• Normal Reaction

• Weight

What is the role of friction in the context of the block being pulled up the slope?

• It acts to maintain the block's constant speed.

• It acts to accelerate the block.

• It acts to increase the tension in the cable.

• It acts to decelerate the block.

What is the angle used to resolve the weight component acting down the slope?

• 10 degrees

• 12 degrees

• 20 degrees

• 15 degrees

How is the frictional force calculated in this scenario?

• By dividing the tension by the weight component.

• By subtracting the weight component from the tension.

• By multiplying the weight by the sine of the angle.

• By adding the tension and weight components.

What is the final calculated value of the frictional force to two significant figures?

• 1.0 x 10^3 N

• 1.1 x 10^3 N

• 1.2 x 10^3 N

• 1.3 x 10^3 N
