Why are Standard Operation Procedures important in a manufacturing plant?

• Standard Operation Procedures increase errors, decrease safety, and hinder quality control in a manufacturing plant.

• Standard Operation Procedures provide consistency, quality control, efficiency, error reduction, and safety in a manufacturing plant.

• Standard Operation Procedures provide chaos, inconsistency, and inefficiency in a manufacturing plant.

• Standard Operation Procedures are unnecessary, time-consuming, and irrelevant in a manufacturing plant.

Imagine you're trying to push a heavy box across the floor. What kind of friction are you initially encountering?

• Static friction is the force that must be overcome to initiate relative motion between two surfaces in contact.

• Static friction is the force that is not affected by the weight of the object.

• Static friction is the force that increases as motion continues.

• Static friction is the force that keeps an object in motion.

Imagine you're pushing a heavy box across the floor. What role does Kinetic Friction play in this scenario?

• Kinetic friction is the force that helps the box move smoothly without any resistance.

• Kinetic friction is the force that attracts the box towards the floor when they are in motion.

• Kinetic friction is the force that increases the speed of the box in motion.

• Kinetic friction is the force that opposes the relative motion between the box and the floor when they are moving past each other.

If you load more cargo onto a truck, how does this affect the force needed to keep the truck moving at a constant speed?

• The force needed to keep the truck moving at a constant speed becomes negative.

• The force needed to keep the truck moving at a constant speed remains the same.

• The force needed to keep the truck moving at a constant speed increases.

• The force needed to keep the truck moving at a constant speed decreases.

How do you make a car accelerate faster?

• Keep the force (gas pedal pressure) constant and increase its mass (add more cargo).

• Decrease the force (gas pedal pressure) or increase its mass (add more cargo).

• Decrease the force (gas pedal pressure) and decrease its mass (remove cargo).

• Increase the force (gas pedal pressure) or decrease its mass (remove cargo).

What does it mean when a car is experiencing negative acceleration while moving forward?

• Changing direction.

• Slowing down in the direction of its motion.

• Moving at a constant speed.

• Speeding up in the direction of its motion.

When pushing a shopping cart with groceries, the force applied to the cart is measured in what?

• A unit of force called a Newton

• A unit of measurement called Force

• A type of fruit that can be made into a snack.

• A brand of computer
